Description

Technical Field

[0001] The present application relates to the technical field of resource response control, and in particular to a resource response control method, device, equipment and storage medium. Background Art

[0002] A virtual power plant is a power coordination management system that uses advanced information communication and software systems to aggregate and coordinate optimization of resources such as energy storage systems, controllable loads, and electric vehicles. As a special power plant, it participates in the electricity market and power grid operation. The most attractive feature of a virtual power plant is its ability to aggregate resources to participate in the operation of the electricity market and ancillary service market, and provide management and ancillary services for distribution and transmission networks.

[0003] Virtual power plants usually access a variety of different resources, aggregate all of these resources and participate in the grid ancillary service market. However, the adjustable capabilities of different resources vary in different scenarios, and some resources may not be able to participate in ancillary services every time. Virtual power plants do not carry out precise regulation and control, and it is difficult to fully and accurately respond to grid dispatching needs, affecting the completion of dispatching plans issued by the grid dispatching platform, and the normal operation of resources is also affected.

[0004] The above contents are only used to assist in understanding the technical solution of the present application and do not constitute an admission that the above contents are prior art. Summary of the invention

[0005] The main purpose of this application is to provide a resource response control method, device, equipment and storage medium, aiming to solve the technical problem in the prior art that virtual power plants cannot accurately control resource responses and are difficult to complete scheduling plans.

[0006] In a first aspect, the present application provides a resource response control method, the method comprising the following steps:

[0007] Upon receiving the scheduling demand from the scheduling platform, at least one adjustable resource for the target demand day is determined based on the response assessment results of the access resources;

[0008] Aggregating the load forecast curves of the adjustable resources into a total load curve, and uploading the total load curve to the scheduling platform;

[0009] Receiving the dispatching plan curve fed back by the dispatching platform according to the total load curve, and decomposing the dispatching plan curve to determine the response plan curve corresponding to each adjustable resource;

[0010] The response plan curve is sent to corresponding adjustable resources, so that each adjustable resource responds on the target demand day based on the response plan curve.

[0011] In this solution, the access resources are assessed, the adjustable resources and non-adjustable resources on the demand day are distinguished according to the assessment results, the adjustable resources are aggregated, and the corresponding data are reported to the dispatching platform. After receiving the dispatching plan issued by the dispatching platform, the plan is accurately decomposed into the corresponding adjustable resources for response, ensuring that each adjustable resource can respond normally within its capacity and participate in the power grid ancillary services on the demand day, realizing precise regulation of resource response, and being able to accurately respond to power grid dispatching needs, improve the response volume, and the dispatching plan can be completed accurately and smoothly.

[0012] In some embodiments, the step of determining at least one adjustable resource for the target demand day based on the response assessment results of the access resources includes: obtaining the response assessment results of the access resources on historical demand days, the response assessment results being either biased or unbiased; determining the number of assessment deviations of the access resources based on the response assessment results of the access resources on historical demand days; and determining at least one adjustable resource for the target demand day among the access resources based on the number of assessment deviations of the access resources.

[0013] By analyzing the historical response of the access resources, it is determined whether there are deviations in the historical demand days. After receiving the invitation, the virtual power plant can find the adjustable resources that can respond on the demand day according to the number of deviations. It can quickly and accurately distinguish between the adjustable resources and non-adjustable resources on the demand day, so that the adjustable resources can be aggregated to participate in the grid ancillary services on the demand day, and the non-adjustable resources will not participate in the grid ancillary services on the demand day, ensuring that the non-adjustable resources can operate normally and stably, realizing precise regulation of resource response, and improving the accuracy of the response.

[0014] In some embodiments, the step of determining at least one adjustable resource for the target demand day in the access resources based on the number of assessment deviations of the access resources includes: based on the number of assessment deviations of the access resources, screening out access resources whose number of assessment deviations is less than or equal to a deviation number threshold as the adjustable resources for the target demand day.

[0015] By setting a deviation number threshold, access resources with deviation times less than or equal to the threshold are used as adjustable resources on demand days. Resources that have failed to participate in grid auxiliary services normally for multiple times can be accurately eliminated, and resources that can participate in grid auxiliary services normally can be retained, thereby accurately distinguishing between adjustable resources and non-adjustable resources on demand days, and then aggregating adjustable resources to participate in grid auxiliary services on demand days, achieving precise regulation of resource responses and improving the accuracy of responses.

[0016] In some embodiments, the step of obtaining the response assessment results of the access resources on the historical demand days includes: obtaining the historical power operation curve and the historical response plan curve of the access resources on the historical demand days; assessing the power response of the access resources on the historical demand days based on the historical power operation curve and the historical response plan curve of the access resources on the historical demand days, and obtaining the response assessment results of the access resources on the historical demand days.

[0017] By analyzing the historical power operation status of each access resource and the corresponding response plan, the historical response completion status of each access resource is determined and the corresponding assessment results are generated. After receiving the invitation, the virtual power plant can accurately distinguish between the adjustable resources and non-adjustable resources on the demand day according to the assessment results, so as to accurately adjust the resource response and improve the accuracy of the response.

[0018] In some embodiments, the step of assessing the power response of the access resource on the historical demand day based on the historical power operation curve and the historical response plan curve of the access resource on the historical demand day to obtain the response assessment result of the access resource on the historical demand day includes: determining the historical power difference of the access resource on the historical demand day based on the historical power operation curve and the historical response plan curve of the access resource on the historical demand day; when the historical power difference of the access resource on the historical demand day meets the deviation condition, determining that the response assessment result of the access resource on the historical demand day is deviated; when the historical power difference of the access resource on the historical demand day does not meet the deviation condition, determining that the response assessment result of the access resource on the historical demand day is unbiased.

[0019] By analyzing the historical power operation status of each access resource and the corresponding response plan, the difference between the data is calculated to determine the historical response completion status of each access resource, so as to judge whether there is a deviation in the historical demand day. The virtual power plant can accurately distinguish between the adjustable resources and non-adjustable resources on the demand day according to the statistical number of deviations, so as to accurately control the resource response and improve the accuracy of the response.

[0020] In some embodiments, the step of decomposing the scheduling plan curve to determine the response plan curve corresponding to each adjustable resource includes: determining the adjustment difference and load power corresponding to each adjustable resource at each planning moment according to the scheduling plan curve, the total load curve and the load forecast curve; determining the response power corresponding to each adjustable resource at each planning moment according to the adjustment difference and load power corresponding to each adjustable resource at each planning moment; obtaining the response plan curve corresponding to each adjustable resource according to the response power corresponding to each adjustable resource at each planning moment.

[0021] By analyzing the dispatch plan curve, the total load curve and the load forecast curve of each adjustable resource, the adjustment amount and load power required for each adjustable resource at each moment are calculated, thereby calculating the response power of each adjustable resource at each moment, and obtaining the response plan curve of each adjustable resource. The virtual power plant can accurately decompose the dispatch plan issued by the dispatch platform to the corresponding adjustable resources for response, ensuring that each adjustable resource can respond normally within its capacity, further ensuring the precise control of resource response, and being able to accurately respond to the grid dispatch needs, improve the response amount, and the dispatch plan can be completed accurately and smoothly.

[0022] In some embodiments, the step of determining the response power corresponding to each adjustable resource at each planned moment based on the adjustment difference and load power corresponding to each adjustable resource at each planned moment includes: adding the adjustment difference and load power corresponding to each adjustable resource at each planned moment to obtain the response power corresponding to each adjustable resource at each planned moment.

[0023] By adding up the adjustment amount and load power required by each adjustable resource at each moment, the response power of each adjustable resource at each moment is calculated, so as to generate a response plan curve for each adjustable resource. In this way, the virtual power plant can accurately decompose the dispatch plan issued by the dispatch platform to the corresponding adjustable resources for response, thereby realizing precise control of resource response.

[0024] In some embodiments, the step of determining the adjustment difference and load power corresponding to each adjustable resource at each planned moment according to the scheduling plan curve, the total load curve and the load forecast curve includes: determining the load power corresponding to each adjustable resource at each planned moment according to the load forecast curve of each adjustable resource; determining the planned power difference corresponding to each planned moment according to the scheduling plan curve and the total load curve; determining the load power difference corresponding to each adjustable resource at each planned moment according to the load power corresponding to each adjustable resource at each planned moment and the historical minimum load power of each adjustable resource on the historical demand day; determining the adjustment difference corresponding to each adjustable resource at each planned moment according to the load power difference corresponding to each adjustable resource at each planned moment and the planned power difference corresponding to each planned moment.

[0025] By calculating the planned power difference and load power difference of each adjustable resource at each moment, the adjustment amount required for each adjustable resource at each moment is calculated using the planned power difference and load power difference of each adjustable resource at each moment, so as to calculate the response power of each adjustable resource at each moment according to the adjustment amount required by each adjustable resource at each moment and the load power, and generate a response plan curve for each adjustable resource. The virtual power plant will accurately decompose the dispatch plan issued by the dispatch platform to the corresponding adjustable resources for response, further ensuring the precise control of resource response and improving the accuracy of response.

[0026] In some embodiments, the step of determining the adjustment difference corresponding to each adjustable resource at each planned moment according to the load power difference corresponding to each adjustable resource at each planned moment and the planned power difference corresponding to each planned moment includes: determining the total load power difference corresponding to each planned moment according to the load power difference corresponding to each adjustable resource at each planned moment; obtaining the correspondence between the planned power difference, the load power difference, the total load power difference and the adjustment difference; determining the adjustment difference corresponding to each adjustable resource at each planned moment according to the planned power difference corresponding to each planned moment, the load power difference corresponding to each adjustable resource at each planned moment, the total load power difference corresponding to each planned moment and the corresponding relationship.

[0027] Through the planned power difference, load power difference and total load power difference, the adjustment amount required for each adjustable resource at each moment is accurately calculated, so as to further calculate the response power of each adjustable resource at each moment according to the adjustment amount required by each adjustable resource at each moment and the load power, and generate the response plan curve of each adjustable resource. In this way, the virtual power plant can accurately decompose the dispatch plan issued by the dispatch platform to the corresponding adjustable resources for response, thereby realizing precise control of resource response.

[0028] In some embodiments, the step of aggregating the load forecast curves of the adjustable resources into a total load curve includes: adding the load forecast curves of the adjustable resources on the target demand day to obtain the total load curve.

[0029] The overall total load curve is obtained by adding up the load forecast curves of each adjustable resource, so that the virtual power plant can report the total load curve to the power grid dispatching platform. After the power grid dispatching platform issues a dispatching plan based on the reported total load curve, the issued execution plan is accurately decomposed into the corresponding adjustable resources for response, thereby achieving precise control of resource response, being able to accurately respond to power grid dispatching needs, ensuring the response volume, and enabling the dispatching plan to be completed accurately and smoothly.

[0030] In some embodiments, before the step of aggregating the load forecast curves of the adjustable resources into a total load curve, the step also includes: obtaining power operation data of the adjustable resources; predicting the load of the adjustable resources on the target demand day based on the power operation data of the adjustable resources, and generating a load forecast curve for the adjustable resources.

[0031] The load situation on the demand day is predicted by the load situation of the adjustable resources before the demand day, and the corresponding load forecast curve is accurately generated, so that the load forecast curves of all adjustable resources can be aggregated to obtain an accurate total load curve, so that the power grid dispatching platform can issue a dispatching plan according to the reported total load curve, so that the virtual power plant can accurately decompose the issued execution plan to the corresponding adjustable resources for response, realize precise regulation of resource response, and improve the accuracy of response.

[0032] In some embodiments, the step of obtaining the power operation data of the adjustable resource includes: receiving the real-time power of the adjustable resource, and determining the most recent received power of the adjustable resource within the preset period according to the real-time power of the adjustable resource within the preset period; using the most recent received power of the adjustable resource within the preset period as the operating power of the adjustable resource at the last moment of the preset period; and generating the power operation data of the adjustable resource according to the operating power of the adjustable resource at the last moment of the preset period.

[0033] By processing the received data at a regular interval and selecting the most recently received data at each processing as the power in the current cycle, the data of the adjustable resources within a day can be integrated into the successful operation status, which can reduce the amount of calculation while ensuring accuracy, and improve response efficiency and accuracy.

[0034] In a second aspect, to achieve the above-mentioned purpose, the present application further proposes a resource response control device, the resource response control device comprising:

[0035] A resource screening module is used to determine at least one adjustable resource for a target demand day based on a response assessment result of an access resource when a scheduling demand is received from the scheduling platform;

[0036] A plan reporting module, used for aggregating the load forecast curves of the adjustable resources into a total load curve, and uploading the total load curve to the scheduling platform;

[0037] A plan decomposition module is used to receive the scheduling plan curve fed back by the scheduling platform according to the total load curve, and decompose the scheduling plan curve to determine the response plan curve corresponding to each adjustable resource;

[0038] The resource response module is used to send the response plan curve to the corresponding adjustable resources, so that each adjustable resource responds on the target demand day based on the response plan curve.

[0039] In the third aspect, to achieve the above-mentioned purpose, the present application also proposes a resource response control device, which includes: a memory, a processor, and a resource response control program stored in the memory and executable on the processor, and the resource response control program is configured to implement the steps of the resource response control method described above.

[0040] In a fourth aspect, to achieve the above-mentioned purpose, the present application further proposes a storage medium, on which a resource response control program is stored, and when the resource response control program is executed by a processor, the steps of the resource response control method described above are implemented.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0058] At present, more and more new energy sources are being added to the power system, which has brought great impact and fluctuations to the power grid and added a lot of pressure to the power system. At this time, handling the power generation and consumption of new energy and the coordinated management of distributed energy are important issues that need to be solved. Virtual power plants usually play an important role in promoting the transformation to green energy.

[0059] A virtual power plant is a power coordination management system that uses advanced information communication and software systems to aggregate and coordinate optimization of resources such as energy storage systems, controllable loads, and electric vehicles. As a special power plant, it participates in the electricity market and power grid operation. The most attractive feature of a virtual power plant is its ability to aggregate resources to participate in the operation of the electricity market and ancillary service market, and provide management and ancillary services for distribution and transmission networks.

[0060] In actual applications, virtual power plants usually access a variety of different resources, aggregate all of these resources and participate in the grid ancillary service market, but the adjustable capabilities of different resources vary in different scenarios, and some resources may not be able to participate in ancillary services every time. For example: the number of electric vehicle charging users increases on weekends. At this time, charging piles usually do not participate in peak demand response in order to ensure customer needs, or in summer, factories need air conditioning to cool down, and some factory equipment may not be adjusted. The virtual power plant does not perform precise regulation on this, and it is difficult to fully and accurately respond to the grid dispatching needs, affecting the completion of the dispatching plan issued by the grid dispatching platform, and the normal operation of resources is also affected.

[0061] Therefore, the embodiment of the present application assesses the access resources, distinguishes the adjustable resources and non-adjustable resources on the demand day according to the assessment results, aggregates the adjustable resources, reports the corresponding data to the scheduling platform, and after receiving the scheduling plan issued by the scheduling platform, accurately decomposes the plan into the corresponding adjustable resources for response, ensuring that each adjustable resource can respond normally within its capacity and participate in the power grid auxiliary services on the demand day, thereby achieving precise control of resource responses, being able to accurately respond to power grid scheduling needs, and improving the response volume, so that the scheduling plan can be completed accurately and smoothly.

[0062] It should be noted that, since virtual power plants usually regulate power resources, the embodiments described in this application are applied to scenarios in which virtual power plants respond to and control connected power resources.

[0063] This application proposes a resource response control method to solve the technical problem that virtual power plants cannot accurately control resource response and are difficult to complete scheduling plans. Figure 1 , please refer to Figure 1 In this example, the resource response control method includes:

[0064] Step S10, upon receiving a scheduling requirement from the scheduling platform, determining at least one adjustable resource for the target demand day based on the response assessment result of the access resources.

[0065] It should be noted that the executor of this embodiment is a virtual power plant. A resource response control device can be set up in the virtual power plant. A resource response control program is run on the resource response control device. Accurate regulation of resource response is achieved through the resource response control program. It can also be other terminal devices with computing capabilities, and this embodiment does not impose any restrictions on this.

[0066] Access resources usually refer to the power resources that can be aggregated and accessed by the virtual power plant, such as charging piles, V2G, battery swap stations, factory equipment, air conditioning, lighting, electric heating equipment, energy storage equipment, etc., without specific limitations. The response assessment result refers to the result obtained after assessing the response of the resource, usually an assessment of the historical response, for example: assessing the response of the resource on previous demand days, without specific limitations. The assessment can be conducted in advance, and the response assessment result is directly obtained when the dispatch demand of the dispatch platform is received. The assessment can also be conducted after receiving the dispatch demand of the dispatch platform, and the response assessment result is generated after the assessment is completed.

[0067] The dispatching platform is a power grid dispatching platform. In this embodiment, the dispatching demand of the dispatching platform can be a peak load demand or a frequency regulation demand, which is not specifically limited.

[0068] The target demand day refers to the date on which the dispatch plan is currently being arranged, that is, the date on which resource dispatch and demand response are most recently required. It is usually the day after the power grid dispatch platform issues the invitation. Assuming that the target demand day is D-day, the power grid dispatch platform will issue a dispatch demand to the virtual power plant on D-1. The virtual power plant will select the corresponding adjustable resources for response based on the response assessment results of the access resources on D-1.

[0069] Generally speaking, a virtual power plant will aggregate all access resources to participate in grid auxiliary services, but the adjustable capabilities of different resources vary in different scenarios, and some resources may not be able to participate in auxiliary services every time. These access resources that cannot participate in the grid auxiliary services on the target demand day are non-adjustable resources. Correspondingly, access resources that can participate in the grid auxiliary services on the target demand day are adjustable resources. In order to enable precise regulation, this embodiment uses the response assessment results of each access resource to distinguish between adjustable resources and non-adjustable resources, thereby aggregating adjustable resources to participate in the grid auxiliary services on the target demand day, and non-adjustable resources do not participate in the grid auxiliary services on the target demand day, ensuring that non-adjustable resources can operate normally and stably. In order to be able to respond to demand, at least one adjustable resource needs to be selected.

[0070] Step S20, aggregating the load forecast curves of the adjustable resources into a total load curve, and uploading the total load curve to the scheduling platform.

[0071] It should be noted that the load forecast curve refers to the predicted load curve, which is usually the load forecast curve of the adjustable resources on the target demand day. The load curve is also the curve of load power changing over time. The total load curve refers to the overall load curve, which is obtained by aggregating the load forecast curves of all adjustable resources. The scheduling plan curve refers to the curve of the planned scheduling power changing over time, that is, the curve composed of the planned scheduling power at each moment, which is usually the scheduling plan curve for the overall adjustable resources.

[0072] It is understandable that the virtual power plant needs to report the total load curve to the power grid dispatching platform. The power grid dispatching platform formulates a dispatching plan curve based on the reported total load curve and sends the dispatching plan curve to the virtual power plant.

[0073] Step S30, receiving the dispatching plan curve fed back by the dispatching platform according to the total load curve, and decomposing the dispatching plan curve to determine the response plan curve corresponding to each adjustable resource.

[0074] It should be noted that the response plan curve refers to the curve of the power that needs to be responded to over time, that is, the curve composed of the power that needs to be responded to at each moment. Since this embodiment selects adjustable resources for the final response, the virtual power plant needs to decompose the scheduling plan curve after receiving the scheduling plan curve, and decompose it into the response plan curve of each adjustable resource, so that each adjustable resource can respond within its capacity.

[0075] Step S40: Send the response plan curve to the corresponding adjustable resources, so that each adjustable resource responds on the target demand date based on the response plan curve.

[0076] It can be understood that the virtual power plant sends out the response plan curve of each adjustable resource so that each adjustable resource responds to the demand according to the received response plan curve.

[0077] In this embodiment, the access resources are assessed, the adjustable resources and non-adjustable resources on the demand day are distinguished according to the assessment results, the adjustable resources are aggregated, and the corresponding data is reported to the dispatching platform. After receiving the dispatching plan issued by the dispatching platform, the plan is accurately decomposed into the corresponding adjustable resources for response, ensuring that each adjustable resource can respond normally within its capacity and participate in the power grid auxiliary services on the demand day, realizing precise regulation of resource response, and being able to accurately respond to power grid dispatching needs, improve the response volume, and the dispatching plan can be completed accurately and smoothly.

[0078] In some embodiments, in order to accurately distinguish between adjustable resources and non-adjustable resources in access resources, historical response situations of access resources may be assessed.

[0079] As an example, see Figure 2 The step of determining at least one adjustable resource on a target demand day based on the response assessment result of the access resource includes:

[0080] Step S101, obtaining a response assessment result of an access resource on a historical demand day, where the response assessment result is either biased or unbiased.

[0081] It should be noted that historical demand days refer to dates on which resource scheduling and demand response have been carried out in the past. They can be all dates on which resource scheduling and demand response have been carried out in the past, or a part of them can be selected. For example, historical demand days that meet the scenario of the target demand day are selected. There is no specific limitation on this.

[0082] The response assessment result can be either biased or unbiased, that is, the response assessment result can be biased or unbiased. A biased response assessment result indicates that there is a problem with the response of the access resource on the corresponding historical demand day and a normal response was not performed. An unbiased response assessment result indicates that the access resource completed the response normally on the corresponding historical demand day.

[0083] Step S102, determining the number of assessment deviations of the access resource according to the response assessment results of the access resource on the historical demand day.

[0084] It should be noted that the number of assessment deviations, i.e., the number of times the response assessment results are deviated, is obtained by collecting statistics on the response assessment results of the access resources on historical demand days.

[0085] Step S103: determining at least one adjustable resource for the target demand day from the access resources according to the number of assessment deviations of the access resources.

[0086] Specifically, according to the response assessment results of the access resources on the historical demand days, the number of assessment deviations of the access resources is counted, so as to screen out suitable adjustable resources according to the number of assessment deviations of each access resource.

[0087] By analyzing the historical response of the access resources, it is determined whether there are deviations in the historical demand days. After receiving the invitation, the virtual power plant can find the adjustable resources that can respond on the demand day according to the number of deviations. It can quickly and accurately distinguish between the adjustable resources and non-adjustable resources on the demand day, so that the adjustable resources can be aggregated to participate in the grid ancillary services on the demand day, and the non-adjustable resources will not participate in the grid ancillary services on the demand day, ensuring that the non-adjustable resources can operate normally and stably, realizing precise regulation of resource response, and improving the accuracy of the response.

[0088] Furthermore, the higher the number of assessment deviations, the more times the resource has not participated in the grid ancillary services normally, that is, the greater the possibility that the resource cannot participate in the grid ancillary services on the target demand day.

[0089] As an example, based on the number of assessment deviations of the access resources, the step of determining at least one adjustable resource for the target demand day in the access resources includes: based on the number of assessment deviations of the access resources, screening out access resources whose number of assessment deviations is less than or equal to a deviation number threshold as adjustable resources for the target demand day.

[0090] It should be noted that the deviation number threshold is the set threshold of the assessment deviation number, for example: 10 times, which can be flexibly adjusted according to actual needs and is not specifically limited.

[0091] When the number of assessment deviations of an access resource is greater than the deviation number threshold, it is considered that the access resource cannot participate in the grid ancillary service on the target demand day, and the access resource is an unadjustable resource. When the number of assessment deviations of an access resource is less than or equal to the deviation number threshold, it is considered that the access resource can participate in the grid ancillary service on the target demand day, and the access resource is an adjustable resource.

[0092] It is understandable that if there are new access resources that have not participated in grid ancillary services, the new access resources do not respond to the assessment results, the number of assessment deviations is 0, and the new access resources are usually assumed to be adjustable resources. New access resources usually need to be tested for a period of time in order to generate corresponding historical data for assessment. The duration of the trial operation can be determined according to actual needs, for example: three months, and there is no specific limit on this. After the trial operation is completed, the resources will be put into formal operation.

[0093] By setting a deviation number threshold, access resources with deviation times less than or equal to the threshold are used as adjustable resources on demand days. Resources that have failed to participate in grid auxiliary services normally for multiple times can be accurately eliminated, and resources that can participate in grid auxiliary services normally can be retained, thereby accurately distinguishing between adjustable resources and non-adjustable resources on demand days, and then aggregating adjustable resources to participate in grid auxiliary services on demand days, achieving precise regulation of resource responses and improving the accuracy of responses.

[0094] In some embodiments, corresponding assessment results may generally be generated based on historical response completion status of access resources.

[0095] As an example, the steps of obtaining the response assessment results of the access resources on the historical demand days include: obtaining the historical power operation curve and the historical response plan curve of the access resources on the historical demand days; assessing the power response of the access resources on the historical demand days based on the historical power operation curve and the historical response plan curve of the access resources on the historical demand days, and obtaining the response assessment results of the access resources on the historical demand days.

[0096] It should be noted that the historical power operation curve refers to the curve composed of the power of the access resources at various times on the historical demand day, which reflects the actual power operation status of the access resources on the historical demand day. The historical response plan curve refers to the curve composed of the power that the access resources need to respond to at various times on the historical demand day.

[0097] Even if the access resource normally participates in the grid ancillary services on the historical demand day, the historical power operation curve and the historical response plan curve of the access resource on the historical demand day will not be exactly the same, and there will usually be certain differences. Therefore, it is necessary to further analyze the difference between the historical power operation curve and the historical response plan curve to determine whether there is a large deviation between the actual power and the required response power, so as to judge whether the response assessment result of the access resource on the historical demand day is biased or not.

[0098] By analyzing the historical power operation status of each access resource and the corresponding response plan, the historical response completion status of each access resource is determined and the corresponding assessment results are generated. After receiving the invitation, the virtual power plant can accurately distinguish between the adjustable resources and non-adjustable resources on the demand day according to the assessment results, so as to accurately adjust the resource response and improve the accuracy of the response.

[0099] In some embodiments, the power response of the access resource on the historical demand day is assessed based on the historical power operation curve and the historical response plan curve of the access resource on the historical demand day, and the step of obtaining the response assessment result of the access resource on the historical demand day includes: determining the historical power difference of the access resource on the historical demand day based on the historical power operation curve and the historical response plan curve of the access resource on the historical demand day; when the historical power difference of the access resource on the historical demand day meets the deviation condition, determining that the response assessment result of the access resource on the historical demand day is biased; when the historical power difference of the access resource on the historical demand day does not meet the deviation condition, determining that the response assessment result of the access resource on the historical demand day is unbiased.

[0100] It should be noted that the historical power difference refers to the difference between the corresponding values ​​in the historical power operation curve and the historical response plan curve at the same time. If the historical power difference values ​​at each moment are large, it means that the deviation between the historical power operation curve and the historical response plan curve is large, that is, the deviation between the actual power and the response power that needs to be achieved is large. At this time, it can be considered that the response deviation of the access resource on the historical demand day is large, and the access resource did not respond normally. The response assessment result is usually biased. If the historical power difference values ​​at each moment are small, it means that the deviation between the historical power operation curve and the historical response plan curve is small, that is, the deviation between the actual power and the response power that needs to be achieved is small. At this time, it can be considered that the response deviation of the access resource on the historical demand day is small, and the access resource responds normally, and the response assessment result is usually unbiased. If the historical power difference values ​​at each moment are large or small, it is usually impossible to directly judge the size of the response deviation at this time, so this embodiment sets a deviation condition.

[0101] The deviation condition is a condition used to measure the deviation between the historical power operation curve and the historical response plan curve, for example: the variance is greater than the set variance threshold, the standard deviation is greater than the set variance threshold, and can be set according to actual needs, and there is no specific limitation on this. If the historical power difference of the access resource on the historical demand day does not meet the deviation condition, the corresponding response assessment result is no deviation; if the historical power difference of the access resource on the historical demand day meets the deviation condition, the corresponding response assessment result is deviation.

[0102] Exemplarily, assuming that the deviation condition is that the variance is greater than the set variance threshold, when the variance of the historical power difference value of the access resource on the historical demand day is greater than the variance threshold, it is considered that the historical power difference value of the access resource on the historical demand day meets the deviation condition, and the response assessment result of the access resource on the historical demand day is biased; when the variance of the historical power difference value of the access resource on the historical demand day is less than or equal to the variance threshold, it is considered that the historical power difference value of the access resource on the historical demand day does not meet the deviation condition, and the response assessment result of the access resource on the historical demand day is unbiased.

[0103] In specific implementation, the historical power operation curve of the access resource on the historical demand day can also be compared with the historical response plan curve and the historical load forecast curve to further ensure the accuracy of the assessment. The historical load forecast curve is a curve composed of the predicted power of the access resource at each moment of the historical demand day. If the deviation between the historical power operation curve of the access resource and the historical load forecast curve is small, and the deviation between the historical power operation curve and the decomposed historical response plan curve is large, it means that the access resource does not actually respond to the grid dispatch demand. The deviation between the historical power operation curve and the historical load forecast curve can also be measured using deviation conditions, which are not specifically limited.

[0104] By analyzing the historical power operation status of each access resource and the corresponding response plan, the difference between the data is calculated to determine the historical response completion status of each access resource, so as to judge whether there is a deviation in the historical demand day. The virtual power plant can accurately distinguish between the adjustable resources and non-adjustable resources on the demand day according to the statistical number of deviations, so as to accurately control the resource response and improve the accuracy of the response.

[0105] In some embodiments, the virtual power plant needs to decompose the received dispatch plan curve into each adjustable resource for response.

[0106] As an example, see Figure 3 The steps of decomposing the scheduling plan curve and determining the response plan curves corresponding to the adjustable resources include:

[0107] Step S301, determining the adjustment difference and load power corresponding to each adjustable resource at each planned time according to the scheduling plan curve, the total load curve and the load forecast curve.

[0108] It should be noted that the planned time refers to the key time of the target demand day, which can be a time set according to the cycle, for example: the planned time set at an interval of 15 minutes, the planned time set at an interval of 30 minutes, and there is no specific limitation on this. At this time, it can be considered that the data at the planned time represents the data situation in the corresponding cycle. For example, if the planned time is set at an interval of 15 minutes, the planned time is {00:15, 00:30, 00:45, 01:00, 01:15, ..., 23:30, 23:45}.

[0109] Step S302: determining the response power corresponding to each adjustable resource at each planned time according to the adjustment difference and load power corresponding to each adjustable resource at each planned time.

[0110] It can be understood that the adjustment difference refers to the amount that the adjustable resource needs to be adjusted at each planning moment, which is usually adjusted based on the load power. The corresponding response power of the adjustable resource at each planning moment is calculated by using the adjustment difference and load power corresponding to the adjustable resource at each planning moment, so that the response plan curve of each adjustable resource can be generated, and the decomposition of the scheduling plan curve is completed.

[0111] Step S303: obtaining a response plan curve corresponding to each adjustable resource according to the response power corresponding to each adjustable resource at each planned time.

[0112] It should be understood that after the virtual power plant receives the dispatch plan curve, it needs to decompose the dispatch plan curve. If the adjustable resources on the target demand day are A, B, and C, then when decomposing the dispatch plan curve, it only needs to decompose the dispatch plan curve into resources A, B, and C. The decomposed response plan curve will be sent to the corresponding adjustable resources. A, B, and C will respond according to the response plan curve on the target demand day to complete the dispatch requirements of the target demand day.

[0113] By analyzing the dispatch plan curve, the total load curve and the load forecast curve of each adjustable resource, the adjustment amount and load power required for each adjustable resource at each moment are calculated, thereby calculating the response power of each adjustable resource at each moment, and obtaining the response plan curve of each adjustable resource. The virtual power plant can accurately decompose the dispatch plan issued by the dispatch platform to the corresponding adjustable resources for response, ensuring that each adjustable resource can respond normally within its capacity, further ensuring the precise control of resource response, and being able to accurately respond to the grid dispatch needs, improve the response amount, and the dispatch plan can be completed accurately and smoothly.

[0114] In some embodiments, the adjustment amount required for each adjustable resource at each moment can be calculated using the planned power difference and the load power difference of each adjustable resource at each moment.

[0115] As an example, the steps of determining the adjustment difference and load power corresponding to each adjustable resource at each planned moment according to the scheduling plan curve, the total load curve and the load forecast curve include: determining the load power corresponding to each adjustable resource at each planned moment according to the load forecast curve of each adjustable resource; determining the planned power difference corresponding to each planned moment according to the scheduling plan curve and the total load curve; determining the load power difference corresponding to each adjustable resource at each planned moment according to the load power corresponding to each adjustable resource at each planned moment and the historical minimum load power of each adjustable resource on the historical demand day; determining the adjustment difference corresponding to each adjustable resource at each planned moment according to the load power difference corresponding to each adjustable resource at each planned moment and the planned power difference corresponding to each planned moment.

[0116] It should be noted that the planned power difference refers to the difference between the power that needs to be scheduled on the scheduling curve at the same planning moment and the overall load power on the total load curve. The data corresponding to each planning moment in the load forecast curve is the load power. The historical minimum load power of the adjustable resource on the historical demand day refers to the minimum load power of the adjustable resource at the corresponding moment of the historical demand day. It is necessary to first determine the load power of the adjustable resource at the corresponding moment of all historical demand days and select the minimum value from them. The load power difference refers to the difference between the load power at the same planning moment and the historical minimum load power.

[0117] For example, assuming that the adjustable resource is , if resources can be adjusted At the planning time The load power is , adjustable resources Planning time on historical demand days The minimum load power is , then you can adjust the resources At the planning time Load power difference Load power and minimum load power The difference, that is ; If the scheduling plan curve is at the planning time The dispatch power is , the total load curve at the planned time The overall load power is , at this time the planned time Planned power difference For dispatching power and overall load power The difference, that is .

[0118] It can be understood that the adjustment difference corresponding to the adjustable resource at each planned moment is calculated based on the load power difference corresponding to the adjustable resource at each planned moment and the planned power difference corresponding to each planned moment.

[0119] By calculating the planned power difference and load power difference of each adjustable resource at each moment, and using the planned power difference and load power difference of each adjustable resource at each moment, the adjustment amount required for each adjustable resource at each moment is calculated, so that according to the adjustment amount required by each adjustable resource at each moment and the load power, the response power of each adjustable resource at each moment is calculated, and the response plan curve of each adjustable resource is generated. The virtual power plant can accurately decompose the scheduling plan issued by the scheduling platform to the corresponding adjustable resources for response, so that each adjustable resource can respond normally within the capacity range, further ensuring the precise control of resource response and improving the accuracy of response.

[0120] In some embodiments, the step of determining the adjustment difference corresponding to each adjustable resource at each planned moment according to the load power difference corresponding to each adjustable resource at each planned moment and the planned power difference corresponding to each planned moment includes: determining the total load power difference corresponding to each planned moment according to the load power difference corresponding to each adjustable resource at each planned moment; obtaining the correspondence between the planned power difference, the load power difference, the total load power difference and the adjustment difference; determining the adjustment difference corresponding to each adjustable resource at each planned moment according to the planned power difference corresponding to each planned moment, the load power difference corresponding to each adjustable resource at each planned moment, the total load power difference corresponding to each planned moment and the correspondence.

[0121] It should be noted that the load power difference of all adjustable resources at the same planning time is added together to calculate the total load power difference corresponding to each planning time. The corresponding relationship between the planned power difference, load power difference, total load power difference and adjustment difference, i.e., the calculation formula of the adjustment difference, is as follows:

[0122]

[0123] In the formula, Represents adjustable resources. Indicates A planned moment, Indicates The adjustable resource is in The adjustment difference corresponding to the planned time is Indicates The total load power difference corresponding to the planned time is: Indicates The adjustable resource is in The load power difference corresponding to the planned time is: , Indicates The planned power difference corresponding to the planned time.

[0124] It can be understood that the planned power difference corresponding to each planned moment, the load power difference corresponding to each adjustable resource at each planned moment, and the total load power difference corresponding to each planned moment are substituted into the above calculation formula to calculate the adjustment difference corresponding to each adjustable resource at each planned moment.

[0125] For example, assuming that the adjustable resource is , , If the planned time The planned power difference is , adjustable resources , , The load power differences are , , , then the planned time The total load power difference is , adjustable resources , , At the planning time The adjustment differences are:

[0126]

[0127]

[0128]

[0129] in, , , Represents adjustable resources , , At the planning time The adjustment difference.

[0130] Through the planned power difference, load power difference and total load power difference, the adjustment amount required for each adjustable resource at each moment is accurately calculated, so as to further calculate the response power of each adjustable resource at each moment according to the adjustment amount required by each adjustable resource at each moment and the load power, and generate the response plan curve of each adjustable resource. In this way, the virtual power plant can accurately decompose the dispatch plan issued by the dispatch platform to the corresponding adjustable resources for response, thereby realizing precise control of resource response.

[0131] As an example, based on the adjustment difference and load power corresponding to each adjustable resource at each planned moment, the step of determining the response power corresponding to each adjustable resource at each planned moment includes: adding the adjustment difference and load power corresponding to each adjustable resource at each planned moment to obtain the response power corresponding to each adjustable resource at each planned moment.

[0132] It can be understood that by adding the adjustment difference corresponding to each adjustable resource at each planned time to the load power, the response power corresponding to each adjustable resource at each planned time can be obtained, that is:

[0133]

[0134] In the formula, Represents adjustable resources. Indicates A planned moment, Indicates The adjustable resource is in The adjustment difference corresponding to the planned time is Indicates The adjustable resource is in The load power corresponding to each planning moment.

[0135] For example, if the resource can be adjusted At the planning time The corresponding regulation difference and load power are and , then you can adjust the resources At the planning time The corresponding response power is , if resources can be adjusted At the planning time The corresponding regulation difference and load power are and , then you can adjust the resources At the planning time The corresponding response power is .

[0136] In this embodiment, the adjustment amount and load power required for each adjustable resource at each moment are added together, and the response power of each adjustable resource at each moment is calculated to generate a response plan curve for each adjustable resource. In this way, the virtual power plant can accurately decompose the scheduling plan issued by the scheduling platform into the corresponding adjustable resources for response, thereby realizing precise control of resource response.

[0137] In some embodiments, the load forecast curves of the adjustable resources on the target demand day need to be aggregated into a total load curve for reporting, and the aggregation can be performed by addition.

[0138] As an example, the step of aggregating the load forecast curves of the adjustable resources on the target demand day into a total load curve includes: adding the load forecast curves of the adjustable resources on the target demand day to obtain the total load curve.

[0139] It should be noted that this embodiment aggregates the load forecast curves of the adjustable resources on the target demand day in an additive manner.

[0140] For example, assuming that the adjustable resource is , , , if resources can be adjusted , , The load forecast curves are , , , then the total load curve obtained by aggregation is .

[0141] The overall total load curve is obtained by adding up the load forecast curves of each adjustable resource, so that the virtual power plant can report the total load curve to the power grid dispatching platform. After the power grid dispatching platform issues a dispatching plan based on the reported total load curve, the issued execution plan is accurately decomposed into the corresponding adjustable resources for response, thereby achieving precise control of resource response, being able to accurately respond to power grid dispatching needs, ensuring the response volume, and enabling the dispatching plan to be completed accurately and smoothly.

[0142] In some embodiments, the load forecast curve can be predicted based on the current power operation conditions.

[0143] As an example, before the step of aggregating the load forecast curves of the adjustable resources on the target demand day into the total load curve, the step also includes: obtaining the power operation data of the adjustable resources; predicting the load of the adjustable resources on the target demand day based on the power operation data of the adjustable resources, and generating the load forecast curve of the adjustable resources.

[0144] It should be noted that the power operation data refers to the current power operation status of the adjustable resources, that is, the power operation status one day before the target demand day. The power operation status one day before the target demand day is used to predict the load power of the target demand day, thereby obtaining the corresponding load forecast curve.

[0145] The load situation on the demand day is predicted by the load situation of the adjustable resources before the demand day, and the corresponding load forecast curve is accurately generated, so that the load forecast curves of all adjustable resources can be aggregated to obtain an accurate total load curve, so that the power grid dispatching platform can issue a dispatching plan according to the reported total load curve, so that the virtual power plant can accurately decompose the issued execution plan to the corresponding adjustable resources for response, realize precise regulation of resource response, and improve the accuracy of response.

[0146] In some embodiments, the step of obtaining power operation data of an adjustable resource includes: receiving the real-time power of the adjustable resource, and determining the most recent received power of the adjustable resource within the preset period based on the real-time power of the adjustable resource within the preset period; using the most recent received power of the adjustable resource within the preset period as the operating power of the adjustable resource at the last moment of the preset period; and generating power operation data of the adjustable resource based on the operating power of the adjustable resource at the last moment of the preset period.

[0147] It should be noted that real-time power refers to the real-time power data of adjustable resources, which can be collected by a data acquisition device and uploaded to the virtual power plant through a gateway. There is no specific limitation on this. The real-time power of adjustable resources is usually collected at a fixed time, that is, it is obtained according to a certain collection frequency. The collection frequency can be collected once per minute, which can be flexibly adjusted according to actual needs. There is no specific limitation on this. For example, assuming that the real-time power is collected once every minute, the virtual power plant receives the real-time power of the adjustable resources once every minute.

[0148] After receiving the real-time power of adjustable resources, the virtual power plant usually sorts out the data and integrates the data according to a certain period. The preset period is the set period for each data integration, for example: 15 minutes, which is usually greater than the collection frequency of real-time power. It can be flexibly adjusted according to actual needs and there is no specific limit on this. The data within each preset period will be integrated into a representative data and stored as the operating power of the data point at the last moment of each preset period.

[0149] The most recent received power refers to the most recent real-time power received within a preset period. In this embodiment, the most recent received power within each preset period is used as the operating power at the last moment of each preset period. Figure 4 , assuming there are multiple preset cycles , , , , then The nearest received power within The operating power at the moment will The nearest received power within The operating power at the last moment of all preset periods is aggregated to obtain the power operating data of the adjustable resources. When generating the load forecast curve, it is usually calculated point by point according to the preset period.

[0150] Exemplarily, assuming the preset cycle is 15 minutes, the virtual power plant performs a calculation every 15 minutes, takes the most recently received data within 15 minutes as the operating power at the last moment of the current 15 minutes, and stores it to obtain the final power operation data. The power operation data at this time can be considered as 15-minute data.

[0151] It is understandable that the planning time usually corresponds to a preset period, for example: the preset period is 15 minutes, there is a data point every 15 minutes, and the decomposed scheduling plan curve is also calculated point by point according to 15 minutes.

[0152] By processing the received data at a regular interval and selecting the most recently received data at each processing as the power in the current cycle, the data of the adjustable resources within a day can be integrated into the successful operation status, which can reduce the amount of calculation while ensuring accuracy, and improve response efficiency and accuracy.

[0153] Reference Figure 5 This embodiment proposes the following scheme to illustrate the implementation process of the resource response control method, specifically:

[0154] The power grid dispatching platform initiates a demand invitation to the virtual power plant one day before the target demand day; the virtual power plant determines the resource adjustment capacity on the day based on the assessment results of the accessed resources, distinguishes between adjustable resources and non-adjustable resources, and aggregates the load forecast curves of the adjustable resources for reporting; the power grid dispatching platform arranges the dispatch plan according to the reported load curve and issues the dispatch plan curve to the virtual power plant; the virtual power plant decomposes the dispatch plan curve and issues the decomposed plan curve to each adjustable resource; the adjustable resources receive the plan curve issued by the virtual power plant and make responses and adjustments on the target demand day.

The adjustable resources are aggregated to participate in the grid auxiliary services on the demand day, and the non-adjustable resources do not participate in the grid auxiliary services on the demand day, thereby ensuring that the non-adjustable resources can operate normally and stably, and the scheduling plan issued by the scheduling platform is decomposed into the corresponding adjustable resources for response, thereby realizing precise control of resource response, being able to accurately respond to the grid scheduling needs, ensuring the response volume, and the scheduling plan can be completed accurately and smoothly.
