Description

Technical Field

[0001] This invention belongs to the field of power automation technology, and specifically relates to a method, device, equipment and medium for ramp-up coordination among multiple types of power market participants. Background Technology

[0002] There are different types of market participants in the electricity market. Considering the different operating characteristics of different types of participants, in order to effectively cope with the changes in the output of new energy sources in the electricity market, appropriate coordination methods need to be adopted during periods of large changes in the net load of the system, so that different types of market participants can cooperate organically to better solve the problem of power balance.

[0003] When ensuring power system balance, market participants can be mainly divided into three categories: The first category consists of conventional energy sources, primarily thermal power, which are not limited by power output or regulation time. The second category comprises new regulation resources, such as energy storage, flexible loads, electric vehicles, and virtual power plants. While these have good regulation capabilities, they are generally limited by power output and regulation time. If resources are not allocated rationally, excessive use of the second category can lead to power output constraints, while the power output of the first category cannot achieve system balance due to ramp-up constraints, resulting in wind and solar power curtailment or load shedding. Flexible resources constrained by power output can be traded as ordinary market participants during periods of low activity, but due to their charging and discharging efficiency, they generally only participate in the market during ramp-up or peak-shaving periods. Market participants constrained by power output find it difficult to provide sustainable power like conventional units, but if needed, their market share can rapidly increase or decrease to accommodate rapid changes in the output of high-proportion renewable energy sources. Please refer to [link to relevant documentation]. Figure 1 As shown, if the ratio of the first and second types of regulating resources is not properly managed, the shaded lines indicate that the energy provided by the second type of regulating resources will lead to wind and solar power curtailment or load shedding due to the depletion of the second type of regulating resources and the insufficient ramp-up rate of the first type of regulating resources. The third type of resources mainly consists of interruptible loads on the load side, with a lower priority, and are implemented when the power imbalance in the grid is too large and the reserves are insufficient. Summary of the Invention

[0004] The purpose of this invention is to provide a method, apparatus, equipment and medium for ramping up and coordinating various types of power market participants, so as to reduce the proportion of wind and solar curtailment or load shedding when a large proportion of new energy sources are connected to the grid.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a method for coordinated ramp-up among multiple types of electricity market participants, comprising:

[0007] Obtain the net load deviation P of the power grid systemn and the start time T of the load deviation start and the end time T end ;

[0008] At time T0, the first type of regulating resource is controlled to perform power ramp-up, and the power change rate of the first type of regulating resource is R. first Determine the end time T end At that time, the ramp power increment R of the first type of regulating resource first ×(T end Is -T0) less than P? n If R first ×(T end -T0)≥P n Control the second type of regulatory resources to coordinate with the first type of regulatory resources in an ascending manner; if R first ×(T end -T0)<P n Control the third type of regulatory resources to coordinate with the first type of regulatory resources in an uphill manner;

[0009] The step of controlling the second type of regulation resource to coordinate with the first type of regulation resource for ramping specifically includes: at time Tt, controlling the power regulation amount of the second type of regulation resource to compensate for the power deficiency of the first type of regulation resource, the power regulation amount of the second type of regulation resource at time Tt is: P second，t =P n -P first，t Where, T0 < T start ;T start ≤T t ≤T end The power regulation of the first type of regulating resource at time Tt is P. first，t =R first *(T t -T0);

[0010] The steps for controlling the third type of regulation resource and the first type of regulation resource to coordinate the ramping process specifically include: calling the constraint conditions to solve the pre-established coordination model to obtain the ramping coordination results of the third type of regulation resource and the first type of regulation resource;

[0011] The first type of regulating resource is conventional energy; the second type of regulating resource is new regulating resource; and the third type of regulating resource is interruptible load on the load side.

[0012] A further improvement of this invention is that, in the step of controlling the second type of regulating resource to coordinate with the first type of regulating resource during ramping, the power change rate of the second type of regulating resource is R. second ;

[0013] The rate of change of power R of the first type of regulating resource firstThe rate of change of power R of the second type of regulating resource second The following constraints must be met:

[0014] (T end -T start )×R first ×T end / 2≤E sec (1)

[0015]

[0016] In the formula, E sec This indicates the energy upper limit of the second type of regulatory resource;

[0017] R second ≤P second,max / T start +R first (3)

[0018] In the formula, P second,max This indicates the maximum power of the second type of regulating resource;

[0019] R second ≤(P first,max -p first ) / T start (4)

[0022]

[0023] A further improvement of this invention is that the first type of regulating resource is thermal power.

[0024] A further improvement of the present invention is that the second type of regulating resource is one or more of energy storage, flexible load, electric vehicle, and virtual power plant.

[0025] A further improvement of this invention is that: in the step of calling the constraint conditions to solve the pre-established coordination model and obtain the ramp-up coordination results of the third type of adjustment resources and the first type of adjustment resources, the pre-established coordination model is:

[0033] b) Target system deviation power limit constraint

[0034]

[0035] c) The adjusted frequencies at each key time point are greater than the minimum frequency constraint required for grid operation.

[0036] After a power imbalance occurs in the power grid system, the third type of regulation resources are put into operation, and the first type of regulation resources begin to ramp up.

[0037] p j,t =R first,j t (10)

[0038] In the formula, R first,j This represents the ramp rate of the first type of regulating resource j;

[0039] The following inequality must be satisfied when adjusting the power:

[0040]

[0041] Where H represents the inertia of the power grid system, f l The grid frequency at critical moment t represents the frequency of the power grid at that moment. l p represents the time at which the critical moment l occurs. i,l p represents the power of the third type of regulating resource i at critical moment l; j,l This represents the power of the first type of regulating resource j at critical moment l.

[0042] A further improvement of the present invention is that: in the step of calling the constraint conditions to solve the pre-established coordination model and obtain the ramping coordination results of the third type of adjustment resources and the first type of adjustment resources, the solution is performed by CPLEX to obtain the ramping coordination results of the third type of adjustment resources and the first type of adjustment resources.

[0043] Secondly, the present invention provides a ramp-up coordination device for multiple types of electricity market participants, comprising:

[0044] The data acquisition module is used to obtain the load deviation P of the new energy output. n and the start time T of the load deviation start and the end time T end ;

[0045] The judgment and control module is used to control the first type of regulating resource to perform power ramping at time T0. The power change rate of the first type of regulating resource is R. first Determine the end time T end At that time, the ramp power increment R of the first type of regulating resource first ×(T end Is -T0) less than P? n If R first ×(T end -T0)≥P n Control the second type of regulatory resources to coordinate with the first type of regulatory resources in an ascending manner; if R first ×(T end -T0)<P n Control the third type of regulatory resources to coordinate with the first type of regulatory resources in an uphill manner;

[0046] The steps for the control module to coordinate the second type of regulation resource with the first type of regulation resource during ramp-up specifically include: at time Tt, controlling the power regulation amount of the second type of regulation resource to compensate for the insufficient power of the first type of regulation resource. The power regulation amount of the second type of regulation resource at time Tt is: P second，t =P n -P first，t Where, T0 < T start ;T start ≤T t ≤T end The power regulation of the first type of regulating resource at time Tt is P. first，t =R first *(T t -T0);

[0047] The steps for the control module to coordinate the third type of regulation resource with the first type of regulation resource for ramping include: calling the constraint conditions to solve the pre-established coordination model and obtaining the ramping coordination results of the third type of regulation resource and the first type of regulation resource;

[0048] The first type of regulating resource is conventional energy; the second type of regulating resource is new regulating resource; and the third type of regulating resource is interruptible load on the load side.

[0049] A further improvement of this invention is that, in the step of determining whether the control module controls the second type of regulating resource to coordinate with the first type of regulating resource for ramping, the power change rate of the second type of regulating resource is R. second ;

[0050] The rate of change of power R of the first type of regulating resource first The rate of change of power R of the second type of regulating resource second The following constraints must be met:

[0051] (T end -T start )×R first ×T end / 2≤E sec (1)

[0052]

[0053] In the formula, E sec This indicates the energy upper limit of the second type of regulatory resource;

[0054] R second ≤P second,max / T start +R first (3)

[0055] In the formula, P second,max This indicates the maximum power of the second type of regulating resource;

[0056] R second ≤(P first,max -p first ) / T start (4)

[0057] In the step of controlling the second type of regulation resource and the first type of regulation resource to coordinate the ramping, under the constraints of formulas (1) to (4), the power of the first type of regulation resource and the second type of regulation resource at each time is obtained by solving.

[0058] A further improvement of this invention lies in: in the step of determining whether the control module controls the second type of regulating resource to coordinate with the first type of regulating resource for ramping, the power change rate R of the second type of regulating resource is... second for:

[0059]

[0060] A further improvement of the present invention is that: the first type of regulating resource is thermal power; the second type of regulating resource is one or more of energy storage, flexible load, electric vehicle, and virtual power plant.

[0061] A further improvement of this invention is that, in the step of determining the control module's call to solve the pre-established coordination model based on constraints to obtain the ramp-up coordination results of the third type of adjustment resources and the first type of adjustment resources, the pre-established coordination model is:

[0062]

[0063] In the formula, c j,p c i,p p represents the cost of the first type of regulating resource j and the power i of the third type of regulating resource. j,t p represents the adjustment power of the first type of regulating resource j at time t. i This represents the adjustment power of the third type of adjustment resource i;

[0064] The constraints include:

[0065] a) Output limit constraint

[0066] 0≤p i ≤p i,max (7)

[0067] 0≤p j,t ≤p j,max (8)

[0068] In the formula, p i,max p represents the maximum adjustable power of the third type of adjustable resource power i; j,max This represents the maximum adjustable power of the first type of adjustable resource j at time t;

[0069] b) Target system deviation power limit constraint

[0070]

[0071] c) The adjusted frequencies at each key time point are greater than the minimum frequency constraint required for grid operation.

[0072] After a power imbalance occurs in the power grid system, the third type of regulation resources are put into operation, and the first type of regulation resources begin to ramp up.

[0073] p j,t =R first,j t (10)

[0074] In the formula, R first,j This represents the ramp rate of the first type of regulating resource j;

[0075] The following inequality must be satisfied when adjusting the power:

[0076]

[0077] Where H represents the inertia of the power grid system, f l The grid frequency at critical moment t represents the frequency of the power grid at that moment. l p represents the time at which the critical moment l occurs. i,l p represents the power of the third type of regulating resource i at critical moment l; j,l This represents the power of the first type of regulating resource j at critical moment l.

[0078] A further improvement of this invention is that, in the step of determining the control module's call to solve the pre-established coordination model under constraints to obtain the ramping coordination results of the third type of adjustment resources and the first type of adjustment resources, CPLEX is used to solve the model and obtain the ramping coordination results of the third type of adjustment resources and the first type of adjustment resources.

[0079] Thirdly, the present invention provides an electronic device including a processor and a memory, wherein the processor is used to execute a computer program stored in the memory to implement the aforementioned method for coordinating the ramping of multiple types of electricity market participants.

[0080] Fourthly, the present invention provides a computer-readable storage medium storing at least one instruction that, when executed by a processor, implements the ramp-up coordination method for multiple types of electricity market participants.

[0081] Compared with the prior art, the present invention has the following beneficial effects:

[0082] This invention provides a method, apparatus, equipment, and medium for ramp-up coordination among various types of electricity market participants; the method includes: obtaining the load deviation P of renewable energy output. n and the start time T of the load deviation start and the end time T end At time T0, the first type of regulating resource is controlled to perform power ramp-up, and the power change rate of the first type of regulating resource is R. first Determine the end time T end At that time, the ramp power increment R of the first type of regulating resource first ×(T end Is -T0) less than P? n If R first ×(T end -T0)≥P n Control the second type of regulatory resources to coordinate with the first type of regulatory resources in an ascending manner; if R first ×(T end -T0)<P nThis invention controls the coordination between the third type of regulation resources and the first type of regulation resources to manage the ramp-up process. Addressing the practical situation of large-scale renewable energy integration, this invention categorizes market participants based on whether they are subject to power constraints. By coordinating research on the potential of power-constrained market participants in improving traditional grid regulation, and considering the physical constraints of different market participant types, it proposes a universal coordination method that incorporates multiple market participants. This method can be applied in electricity spot trading, enabling market coordination where new energy, traditional energy, and energy storage coexist. This aims to reduce the proportion of wind and solar power curtailment or load shedding under the actual situation of large-scale renewable energy integration. Attached Figure Description

[0090] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0091] The following detailed description is exemplary and intended to provide further detailed explanation of the invention. Unless otherwise specified, all technical terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention.

[0092] Example 1

[0093] For Category I regulating resources with relatively low ramp-up rates, effective coordination with Category II market players is needed to improve their ramp-up capabilities. The basis for Category II regulating resources to improve the ramp-up rate of Category I regulating resources is to utilize their ramp-up capabilities until conventional units can catch up to the new power point, such as... Figure 2 As shown. The thin slanted shading line represents the energy provided by the second type of regulating resource, and the thick black solid line represents the operation of the first type of regulating resource. Three factors limit the equivalent ramp rate: 1) the available energy that the second type of regulating resource can charge or discharge; 2) the maximum power that the second type of regulating resource can provide; 3) the power generation limit of the first type of regulating resource. The constraint caused by the energy capacity of the second type of regulating resource can be expressed by equation (1), which means that the area of ​​the thin slanted triangle is less than the sum of the available energy of the second type of regulating resource, and gives the corresponding maximum ramp rate:

[0094] (T end -T start )×R first ×T end / 2≤E sec (1)

[0095]

[0096] In the formula, T end and T start R indicates the start and end times of a transaction. first R second E represents the rate of power change of the first type of regulating resource and the second type of regulating resource. sec This indicates the energy limit for the second type of regulatory resource.

[0097] Meanwhile, Equation (3) shows the limiting results of the power output of the second type of regulating resource and the corresponding maximum ramp rate. This indicates that the power provided by the second type of regulating resource should never exceed its maximum power output limit.

[0098] R second ≤P second,max / T start +R first (3)

[0099] In the formula, P second,max This indicates the maximum power of the second type of regulating resource.

[0100] Furthermore, the constraint arising from the maximum power generation limit is calculated in equation (4). Due to the energy capacity limitation of the second type of regulating resource, the final equivalent output should not exceed the maximum output of the first type of regulating resource.

[0101] R second ≤(P first,max -p first) / T start (4)

[0102] Therefore, the ramp rate of the second type of regulating resource is limited by equations (1) to (4) to obtain the power of the first and second types of resources at each time.

[0103] therefore:

[0104]

[0105] Example 2

[0106] Please see Figure 3 As shown, this invention provides a method for coordinating the ramp-up of various types of electricity market participants, allocating regulation resources into three categories: a first category of regulation resources, a second category of regulation resources, and a third category of regulation resources. The first category of regulation resources is thermal power; the second category of regulation resources is one or more of energy storage, flexible loads, electric vehicles, and virtual power plants; the third category of regulation resources is load-side resources, such as interruptible loads, which are generally only interrupted in emergencies due to insufficient reserves and cannot be sustained. The method specifically includes the following steps:

[0107] S1. Obtain the net load deviation P of the power grid system. n and the start time T of the load deviation start and the end time T end ;

[0108] At times S2 and T0, the first type of regulating resource is controlled to perform power ramp-up, and the power change rate of the first type of regulating resource is R. first Determine the end time T end At that time, the ramp power increment R of the first type of regulating resource first ×(T end Is -T0) less than P? n If R first ×(T end -T0)≥P n Control the second type of regulatory resources to coordinate with the first type of regulatory resources in an ascending manner; if R first ×(T end -T0)<P n Control the third type of regulatory resources to coordinate with the first type of regulatory resources in an uphill manner;

[0109] The step of controlling the second type of regulation resource to coordinate with the first type of regulation resource for ramping specifically includes: at time Tt, controlling the power regulation amount of the second type of regulation resource to compensate for the power deficiency of the first type of regulation resource, the power regulation amount of the second type of regulation resource at time Tt is: P second，t =P n -P first，t Where, T0 < T start ;Tstart ≤T t ≤T end The power regulation of the first type of regulating resource at time Tt is P. first，t =R first *(T t -T0);

[0110] The steps for controlling the third type of regulation resource and the first type of regulation resource to coordinate the ramping process specifically include: calling the constraint conditions to solve the pre-established coordination model to obtain the ramping coordination results of the third type of regulation resource and the first type of regulation resource.

[0111] like Figure 2 As shown, in the steps of coordinating the ramp-up of the second type of regulatory resource with the first type of regulatory resource, the thin shaded diagonal line represents the energy provided by the second type of regulatory resource, and the thick black solid line represents the operation of the first type of regulatory resource. Three factors limit the equivalent ramp-up rate:

[0112] 1) The second type of regulatory resource is the available energy that can be charged or discharged;

[0113] 2) The maximum power that the second type of regulating resource can provide;

[0114] 3) The power generation limit of the first type of regulating resources.

[0115] The constraint caused by the energy capacity of the second type of regulating resources can be expressed by equation (1), which means that the area of ​​the thin-slanted triangle is less than the total available energy of the second type of regulating resources, and gives the corresponding maximum ramp rate:

[0116] (T end -T start )×R first ×T end / 2≤E sec (1)

[0117]

[0118] In the formula, T end and T start R indicates the start and end times of a transaction. first R second E represents the rate of power change of the first type of regulating resource and the second type of regulating resource. sec This indicates the energy limit for the second type of regulatory resource.

[0119] Meanwhile, Equation (3) shows the limiting results of the power output of the second type of regulating resource and the corresponding maximum ramp rate. This indicates that the power provided by the second type of regulating resource should never exceed its maximum power output limit.

[0120] Rsecond ≤P second,max / T start +R first (3)

[0121] In the formula, P second,max This indicates the maximum power of the second type of regulating resource.

[0122] Furthermore, the constraint arising from the maximum power generation limit is calculated in equation (4). Due to the energy capacity limitation of the second type of regulating resource, the final equivalent output should not exceed the maximum output of the first type of regulating resource.

[0123] R second ≤(P first,max -p first ) / T start (4)

[0124] Therefore, the ramp rate of the second type of regulating resource is limited by equations (1) to (4) to obtain the power of the first and second types of resources at each time.

[0125] therefore:

[0126]

[0127] When the first type of regulatory resources cannot reach the target power in the next time period, the third type of regulatory resources are coordinated, and a coordination model for different types of market participants is established to ensure the safety of the power grid frequency.

[0128] Meanwhile, when a large power fault occurs, a third type of regulation resource, such as interruptible loads, can be used. This type of resource is characterized by rapid instantaneous power changes, so the frequency stability of the power grid needs to be monitored.

[0129] In one specific implementation, in the step of solving a pre-established coordination model by invoking constraints to obtain the ramp-up coordination results of the third type of adjustment resources and the first type of adjustment resources, the pre-established coordination model is:

[0130]

[0131] In the formula, c j,p c i,p p represents the cost of the first type of regulating resource j and the power i of the third type of regulating resource. j,t p represents the adjustment power of the first type of regulating resource j at time t. i This represents the adjustment power of the third type of adjustment resource i;

[0132] The constraints include:

[0133] a) Output limit constraint

[0134] 0≤p i ≤p i,max (7)

[0135] 0≤p j,t ≤p j,max (8)

[0136] In the formula, p i,max p represents the maximum adjustable power of the third type of adjustable resource power i; j,max This represents the maximum adjustable power of the first type of adjustable resource j at time t;

[0137] b) Target system deviation power limit constraint

[0138]

[0139] c) The adjusted frequencies at each key time point are greater than the minimum frequency constraint required for grid operation.

[0140] After a power imbalance occurs in the power grid system, the third type of regulation resources are put into operation, and the first type of regulation resources begin to ramp up.

[0141] p j,t =R first,j t (10)

[0142] In the formula, R first,j This represents the ramp rate of the first type of regulating resource j;

[0143] The following inequality must be satisfied when adjusting the power:

[0144]

[0145] Where H represents the inertia of the power grid system, f l The grid frequency at critical moment t represents the frequency of the power grid at that moment. l p represents the time at which the critical moment l occurs. i,l p represents the power of the third type of regulating resource i at critical moment l; j,l This represents the power of the first type of regulating resource j at critical moment l.

[0146] The above model is a quadratic programming problem, which can be solved using mature commercial optimization software such as CPLEX to obtain the adjusted output results of the first type and the third type of adjusted resources.

[0147] Example 3

[0148] Please see Figure 5As shown, this invention provides a ramp-up coordination device for multiple types of electricity market participants, allocating regulation resources into three categories: a first category of regulation resources, a second category of regulation resources, and a third category of regulation resources. The first category of regulation resources is thermal power; the second category of regulation resources includes one or more of energy storage, flexible loads, electric vehicles, and virtual power plants; the third category of regulation resources is load-side resources, such as interruptible loads, which are generally only interrupted in emergencies due to insufficient reserves and cannot be sustained. The device includes:

[0149] The data acquisition module is used to obtain the net load deviation P of the power grid system. n and the start time T of the load deviation start and the end time T end ;

[0150] The judgment and control module is used to control the first type of regulating resource to perform power ramping at time T0. The power change rate of the first type of regulating resource is R. first Determine the end time T end At that time, the ramp power increment R of the first type of regulating resource first ×(T end Is -T0) less than P? n If R first ×(T end -T0)≥P n Control the second type of regulatory resources to coordinate with the first type of regulatory resources in an ascending manner; if R first ×(T end -T0)<P n Control the third type of regulatory resources to coordinate with the first type of regulatory resources in an uphill manner;

[0151] The steps for the control module to coordinate the second type of regulation resource with the first type of regulation resource during ramp-up specifically include: at time Tt, controlling the power regulation amount of the second type of regulation resource to compensate for the insufficient power of the first type of regulation resource. The power regulation amount of the second type of regulation resource at time Tt is: P second，t =P n -P first，t Where, T0 < T start ;T start ≤T t ≤T end The power regulation of the first type of regulating resource at time Tt is P. first，t =R first *(T t -T0);

[0152] The steps for the control module to coordinate the third type of regulation resource with the first type of regulation resource for ramping include: calling the constraint conditions to solve the pre-established coordination model and obtaining the ramping coordination results of the third type of regulation resource and the first type of regulation resource;

[0153] The first type of regulating resource is conventional energy; the second type of regulating resource is new regulating resource; and the third type of regulating resource is interruptible load on the load side.

[0154] In one specific implementation, in the step of determining whether the control module controls the second type of regulating resource to coordinate with the first type of regulating resource for ramping, the power change rate of the second type of regulating resource is R. second ;

[0155] The rate of change of power R of the first type of regulating resource first The rate of change of power R of the second type of regulating resource second The following constraints must be met:

[0156] (T end -T start )×R first ×T end / 2≤E sec (1)

[0157]

[0158] In the formula, E sec This indicates the energy upper limit of the second type of regulatory resource;

[0159] R second ≤P second,max / T start +R first (3)
