[0030] Example 1
[0031] Figure 1 The present invention provides a flowchart of a power load control method according to Embodiment 1. This embodiment is applicable to load regulation of distributed power sources to achieve a power supply balance. The method can be executed by a power load control device, which can be implemented in hardware and / or software. The power load control device can be configured in a computing device capable of executing the power load control method.
[0032] like Figure 1 As shown, the method includes:
[0033] S110. Obtain the predicted power generation corresponding to the target distributed power source, and collect the actual power generation corresponding to the target distributed power source.
[0034] In power systems, to facilitate power supply management across different areas when supplying electricity to electrical equipment, load control terminals are typically used to manage distributed power sources in those areas. For example, taking a new type of load management system as an example, there can be multiple load control terminals associated with this system, and multiple distributed power sources associated with each terminal. The electrical equipment managed by each distributed power source can be pre-defined. The target distributed power source can be understood as one of the distributed power sources associated with a load control terminal. It should be noted that, to ensure the target distributed power source can provide sufficient power to the associated electrical equipment, the daily power supply required by the target distributed power source can be predicted, resulting in a predicted power generation capacity corresponding to the target distributed power source. This ensures that the new load management system sends the corresponding predicted power generation capacity to the target distributed power source. The actual power generation capacity can be understood as the power generation capacity actually supplied by the target distributed power source to each electrical device.
[0035] It should be noted that the predicted power generation can be based on the historical power generation of the target distributed power source, predicting the power generation required by the target distributed power source the following day. For example, the power generation required by the target distributed power source tomorrow can be predicted based on the actual power generation of the target distributed power source today; that is, the predicted power generation required tomorrow is the predicted power generation corresponding to the target distributed power source.
[0036] Specifically, based on the historical power generation provided by the target distributed power source to related electrical equipment, the predicted power generation that the target distributed power source needs to provide to the related electrical equipment the following day can be predicted. Simultaneously, based on power generation data acquisition equipment, the actual power generation corresponding to the target distributed power source can be collected to determine the risk level corresponding to the target distributed power source. Furthermore, the current actual power generation can be used as predictive data to determine the predicted power generation.
[0037] Optionally, the process involves obtaining the predicted power generation corresponding to the target distributed power source and collecting the actual power generation corresponding to the target distributed power source, including: receiving meteorological forecast data sent by the load management system; performing pre-power prediction on the meteorological forecast data based on the power output characteristic model to obtain the predicted power curve corresponding to the target distributed power source; and acquiring the actual power generation corresponding to the target distributed power source at at least one moment based on the power acquisition device.
[0038] The load management system can be understood as a system responsible for providing and monitoring electricity consumption in various regions, such as the power management system of a power plant. Meteorological forecast data can be understood as forecast data corresponding to weather data. The load management system can obtain meteorological forecast data from various meteorological release software or meteorological bureaus and send the received meteorological forecast data to the corresponding load control terminals. The power output characteristic model can be understood as a model used to process the meteorological forecast data. Based on the power output characteristic model, a predicted power curve can be obtained. The predicted power curve can be understood as a curve showing the predicted power generation at each time point corresponding to the target distributed power source, including the predicted power generation at at least one time point.
[0039] Specifically, after receiving meteorological forecast data from the load management system, the data is processed based on the power output characteristic model in the load control terminal to obtain a predicted power curve corresponding to the target distributed power source. This predicted power curve is then used to determine the predicted power generation of the target distributed power source at each time point the following day. Simultaneously, the actual power generation of the target distributed power source at each time point can be obtained using power acquisition equipment.
[0040] It should be noted that since the predicted power generation is based on historical power generation data, it usually differs from the actual power generation. To make the predicted power generation more reliable, the predicted power generation for the next day can be determined based on the actual power generation at the current moment. Furthermore, in daily life, significant weather changes can reduce the power generation capacity of generators connected to the load management system. This can lead to a large discrepancy between the predicted and actual power generation, posing a risk to the target distributed power source's ability to supply power to various electrical devices, and potentially even causing large-scale power outages. Therefore, determining the predicted and actual power generation of the target distributed power source is essential.
[0041] S120. Based on the predicted power generation and the actual power generation, determine the risk level corresponding to the target distributed power source.
[0042] The risk level can be understood as the level of risk associated with whether the target distributed power source can supply power to the electrical equipment. For example, if the target distributed power source suffers from severe power shortage and is unable to provide generating power to the associated electrical equipment, the corresponding risk level needs to be determined based on the severity of the power shortage. Risk levels include high-risk levels and moderate-risk levels.
[0043] Specifically, by comparing the predicted and actual power generation of the target distributed power source, it can be determined whether the target distributed power source can supply power to the electrical equipment normally. For example, if the predicted power generation is less than the actual power generation, it indicates that the load management system or load control terminal is sending less power to the target distributed power source, while the actual power consumption of the electrical equipment is higher. Therefore, the target distributed power source cannot supply power to the electrical equipment normally. Conversely, if the predicted power generation is greater than the actual power generation, it indicates that the load management system or load control terminal is sending more power to the target distributed power source, sufficient for the target distributed power source to provide the corresponding power to each electrical equipment. When the target distributed power source cannot provide sufficient power to the electrical equipment, the risk level of the target power source needs to be determined based on the predicted and actual power generation.
[0044] Optionally, based on the predicted power generation and the actual power generation, the risk level corresponding to the target distributed power source is determined, including: based on a power comparator, the difference between the predicted power generation and the actual power generation at the same time is processed to obtain the power difference to be used at the corresponding time; for each time, if the current power difference corresponding to the current time is greater than a first preset power difference, the risk level of the target distributed power source is determined to be a normal risk level; if the current power difference is greater than a second preset power difference, the risk level of the target distributed power source is determined to be a high risk level.
[0045] In this context, a power comparator can be understood as an instrument or device that compares the predicted power generation with the actual power generation. The power difference to be used can be understood as the difference between the predicted and actual power generation. The current power difference can be understood as the power difference obtained based on the predicted and actual power generation at the current moment. The first preset power difference and the second preset power difference can be understood as pre-set power difference thresholds, which can be used to distinguish different risk levels corresponding to the target distributed power source. It should be noted that the first preset power difference is less than the second preset power difference. In this technical solution, the first preset power difference corresponds to the ordinary risk level, and the second preset power difference corresponds to the high risk level.
[0046] Specifically, after determining the predicted and actual power generation corresponding to the target distributed power source, the power comparator in the load control terminal compares the predicted and actual power generation at the same time to obtain the difference in available power at that time. Based on the comparison result between the difference in available power and a power difference threshold, the risk level corresponding to the target distributed power source is determined. If the current power difference at the current time is greater than a first preset power difference, it indicates that the power difference between the two is small, and the corresponding shortfall in power generation provided by the target distributed power source to the electrical equipment is small, so the risk level of the target distributed power source can be determined as a normal risk level. Conversely, if the current power difference at the current time is greater than a second preset power difference, it indicates that the power difference between the two is large, and the corresponding shortfall in power generation provided by the target distributed power source to the electrical equipment is large, so the risk level of the target distributed power source can be determined as a high risk level.
[0047] S130. Based on the target load control method corresponding to the risk level, load regulation is performed on the target distributed power source to achieve a power supply balance state.
[0048] The target load control method includes load management system control method or load terminal control method, and different risk levels correspond to different load control methods.
[0049] Specifically, load control methods for the target distributed power source can include load management system control and load terminal control. Depending on the risk level, different load control methods can be used to control the load of the target distributed power source so that the target distributed power source can achieve a power supply balance state, that is, the power generation received by the target distributed power source can provide sufficient power generation to the associated electrical equipment.
[0050] Optionally, when the risk level is ordinary risk level, the grid frequency to be used corresponding to the target distributed power source is determined; if the grid frequency to be used is less than the grid frequency threshold, a load switch control command is sent to the target distributed power source so that the target distributed power source can regulate the corresponding load control switch based on the load switch command.
[0051] Here, the grid frequency to be used can be understood as the grid frequency calculated in real time by the load control terminal through the AC power supply. The grid frequency threshold can be understood as the frequency value used to determine whether the grid frequency to be used meets the load grid frequency standard. The load control switch command can be understood as the command used to start or stop the load control switch.
[0052] Specifically, when the risk level is ordinary risk level, the target distributed power source can be controlled using a load control terminal. In this case, it is necessary to determine whether the corresponding load control switches need to be shut down based on whether the grid frequency to be used by the target distributed power source is less than the grid frequency threshold. If so, the load control terminal can send load switch control commands to the target distributed power source, so that the target distributed power source shuts down the corresponding number of load control switches based on the load control commands.
[0053] It should be noted that a target distributed power source can be associated with multiple load control switches. Depending on the risk level, a corresponding number of load control switches can be turned off. For example, if there are three load control switches, and the target distributed power source can supply power normally, all load control switches associated with the target distributed power source can be turned on. When the risk level is normal, one load control switch can be turned off. When the risk level is high, two load control switches can be turned off.
[0054] Optionally, after regulating the target distributed power source according to the target load control method corresponding to the risk level, the method further includes: obtaining the undetermined regulation state corresponding to the target distributed power source, and feeding the undetermined regulation state back to the load management system so that the load management system can perform a status assessment based on the undetermined regulation state.
[0055] The "control status to be determined" can be understood as the state of whether the corresponding load control switch performs corresponding control according to the load control command after the target distributed power source is turned off or started. The control status to be determined includes control success status or control failure status.
[0056] Specifically, in order to ensure the effectiveness of the control of the target distributed power source, after the load control of the target distributed power source is performed, the control status to be determined can be obtained, and the control status to be determined can be used to determine whether the control of the target distributed power source is successful.
[0057] The technical solution of this embodiment obtains the predicted power generation corresponding to the target distributed power source and collects the actual power generation corresponding to the target distributed power source. The predicted power generation corresponding to the target distributed power source is determined through meteorological forecast data, and the actual power generation corresponding to the target distributed power source is collected based on power acquisition equipment. The risk level corresponding to the target distributed power source is determined based on the predicted power generation and the actual power generation. Based on the predicted power generation and the actual power generation, the risk level corresponding to the target distributed power source is determined. The risk level is further determined based on the relationship between the difference in available power and the first preset power difference and the second preset power difference. The target load control method corresponding to the target distributed power source is then determined based on the risk level. According to the target load control method corresponding to the risk level, the load of the target distributed power source is regulated to achieve a power supply balance. When the risk level is high risk, a load management system control method is used to regulate the load of the target distributed power source; when the risk level is ordinary risk, a load terminal control method is used to regulate the target distributed power source to achieve a power supply balance. This solves the problem of inaccurate and untimely regulation of the target distributed power source, and achieves the effect of accurately regulating the target distributed power source according to the actual situation.
[0058] Example 2
[0059] Figure 2 The flowchart of a power load control method provided in Embodiment 2 of the present invention is shown. Optionally, when the risk level is a normal risk level, the target distributed power source is regulated based on the target load control mode corresponding to the normal risk level.
[0060] like Figure 2 As shown, the method includes:
[0061] S210. Obtain the predicted power generation corresponding to the target distributed power source, and collect the actual power generation corresponding to the target distributed power source.
[0062] S220. Based on the predicted power generation and the actual power generation, determine the risk level corresponding to the target distributed power source.
[0063] S230. When the risk level is high risk level, determine the power supply status corresponding to the target distributed power source at the corresponding time based on the power difference of each power to be used.
[0064] The power supply status includes either an unbalanced power supply status or a balanced power supply status.
[0065] Specifically, the power supply status of the target distributed power source can be determined by the difference in the power available. When the risk level is high risk, the power supply status of the target distributed power source is usually unbalanced.
[0066] S240. When the power supply status is in a power supply imbalance state, determine the target load handling method corresponding to the target distributed power source, so as to perform load regulation on the target distributed power source based on the target load handling method.
[0067] In this technical solution, when the power supply status of the target distributed power source is unbalanced, the load management system can be used to regulate the target distributed system.
[0068] Optionally, determining the target load handling method corresponding to the target distributed power source includes: determining the load deficit ratio corresponding to the target distributed power source; determining the load to be reduced corresponding to the target distributed power source based on the load deficit ratio, and sending the load to be reduced to the target distributed power source so that the target distributed power source can regulate the associated load control switch.
[0069] The load deficit ratio can be understood as the proportion of power generation that is lacking when the target distributed power source cannot supply power to the electrical equipment normally. The load deficit ratio can be determined based on the ratio of actual power generation to predicted power generation. For example, if the predicted power generation is 100kW and the actual power generation is 70kW, then the load deficit ratio is 30%. The load to be reduced can be understood as the load determined based on the load deficit ratio, i.e., the power generation. For example, when the load deficit ratio is 30%, the target distributed power source should be controlled to provide 30% less power to the electrical equipment to ensure the normal operation of each electrical device and prevent power outages.
[0070] Specifically, when the risk level of the target distributed power source is high-risk, it indicates that the power supply status of the target distributed power source is unbalanced. In this case, the load deficit ratio corresponding to the target distributed power source can be determined based on the load control terminal, and the load deficit ratio can be sent to the load management system so that the load management system can regulate the target distributed power source. Specifically, the load to be reduced corresponding to the target distributed power source can be determined based on the load deficit ratio, and the load to be reduced can be sent to the target distributed power source so that the target distributed power source can control the corresponding number of load control switches to close according to the load to be reduced.
[0071] The technical solution of this embodiment obtains the predicted power generation corresponding to the target distributed power source and collects the actual power generation corresponding to the target distributed power source. The predicted power generation corresponding to the target distributed power source is determined through meteorological forecast data, and the actual power generation corresponding to the target distributed power source is collected based on power acquisition equipment. The risk level corresponding to the target distributed power source is determined based on the predicted power generation and the actual power generation. Based on the predicted power generation and the actual power generation, the risk level corresponding to the target distributed power source is determined. The risk level is further determined based on the relationship between the difference in available power and the first preset power difference and the second preset power difference. The target load control method corresponding to the target distributed power source is then determined based on the risk level. According to the target load control method corresponding to the risk level, the load of the target distributed power source is regulated to achieve a power supply balance. When the risk level is high risk, a load management system control method is used to regulate the load of the target distributed power source; when the risk level is ordinary risk, a load terminal control method is used to regulate the target distributed power source to achieve a power supply balance. This solves the problem of inaccurate and untimely regulation of the target distributed power source, and achieves the effect of accurately regulating the target distributed power source according to the actual situation.
[0072] Example 3
[0073] In a specific example, taking a high-penetration distributed power source as the target, a load control system adapted to the access management of high-penetration distributed power sources is described. (See [link to relevant documentation]). Figure 3The load control system includes a new type of load management system master station, load control terminals, distributed power sources, and intelligent control switches. The load management system master station connects to the load control terminals via a wide area communication network. The load control terminals connect to the distributed power sources and intelligent control switches via a local communication network. The wide area communication network includes channels such as a 230MHz dedicated power line, a mobile virtual private network (VPN), and a public mobile communication network, responsible for establishing a secure channel between the new type of load management system master station and the load control terminals. The local communication network includes Ethernet, fieldbus, etc. The new load management system master station includes a distributed power management module, an adjustable load management module, and a load control execution module. The distributed power management module of the load control system master station collects the daytime power generation of the target distributed power source at different times, and 15-minute real-time power generation data. The adjustable load acquisition module of the load control system master station collects 15-minute real-time power consumption data of the adjustable load within the user's system. The load control strategy algorithm module of the load control system master station receives load adjustment instructions from the dispatch center, decomposes the instructions, and finally sends adjustment instructions to the user's load control terminal. The load control terminal includes a distributed power management module, an adjustable load management module, a load control instruction receiving module, and a load control strategy management module. The distributed power management module of the load control terminal can predict the output of distributed power sources and collect real-time power generation data. The load control terminal's adjustable load management module can collect operational data of adjustable loads and send control commands to the intelligent control switch. The load control command receiving module of the load control terminal can receive load control commands from the load control system's master station via a wide area communication network. The load control strategy management module of the load control terminal can configure the control combinations and timing of adjustable loads. Distributed power sources refer to distributed generation facilities connected to the user's internal feeder network that cannot be managed by dispatching, including distributed photovoltaic, wind power, and self-provided generator sets, whose grid connection points have measuring devices. Intelligent control switches include intelligent circuit breakers, electrical equipment control protocol converters, and other devices, which connect to the load control terminal via a local communication network and can automate the switching and regulation of electrical equipment.
[0074] It should be noted that this technical solution can be applied to the aforementioned load control system, such as... Figure 4 As shown, Figure 4 This is a flowchart illustrating a power load control method provided in this embodiment. The load management system master station can send meteorological forecast data to the load control terminal via a wide area communication network. After receiving the meteorological forecast data, it performs power prediction based on the power output characteristic model to obtain the day-ahead predicted power curve P. F(That is, predicting the power curve), to predict the required power generation of the target distributed power source the following day based on the predicted power curve. Simultaneously, the actual power generation P of the target distributed power source is obtained based on the power acquisition equipment. G After obtaining the actual generated power corresponding to the target distributed power source, the actual generated power P is transmitted via a wide area communication network. G The load control system master station is sent to the load control terminal; the day-ahead forecast power curve P is sent to the load control terminal every 15 minutes. F The power generation P of distributed power sources G The difference is calculated by a comparator (i.e., a power comparator) to obtain the difference in usable power, which is used to determine the risk level corresponding to the target distributed power source. If the risk level is a normal risk level, the load control terminal calculates the grid frequency in real time through the AC power supply. When the grid frequency drops to the configured action threshold (i.e., the grid frequency threshold), it sends a load switch control command to the target distributed power source, enabling the target distributed power source to regulate the corresponding load control switches based on the load switch command, such as controlling the corresponding number of load control switches to close. If the risk level is determined to be a high risk level based on the difference in usable power, it is determined whether there is a risk of power imbalance in the target distributed power source. If so, the load management system master station performs intraday load forecasting. For example, if there is insufficient power supply capacity due to abnormal weather changes, the distributed power source user load control ratio is determined according to the load deficit ratio, and this ratio value is sent to the distributed power source user load control terminal. The load control terminal determines the load Pc to be reduced (i.e., the load to be reduced) based on the issued load control ratio and the power generation output difference, and sends the load to be reduced to the target distributed power source, enabling the target distributed power source to regulate the associated load control switches.
[0075] The technical solution of this embodiment obtains the predicted power generation corresponding to the target distributed power source and collects the actual power generation corresponding to the target distributed power source. The predicted power generation corresponding to the target distributed power source is determined through meteorological forecast data, and the actual power generation corresponding to the target distributed power source is collected based on power acquisition equipment. The risk level corresponding to the target distributed power source is determined based on the predicted power generation and the actual power generation. Based on the predicted power generation and the actual power generation, the risk level corresponding to the target distributed power source is determined. The risk level is further determined based on the relationship between the difference in available power and the first preset power difference and the second preset power difference. The target load control method corresponding to the target distributed power source is then determined based on the risk level. According to the target load control method corresponding to the risk level, the load of the target distributed power source is regulated to achieve a power supply balance. When the risk level is high risk, a load management system control method is used to regulate the load of the target distributed power source; when the risk level is ordinary risk, a load terminal control method is used to regulate the target distributed power source to achieve a power supply balance. This solves the problem of inaccurate and untimely regulation of the target distributed power source, and achieves the effect of accurately regulating the target distributed power source according to the actual situation.
[0076] Example 4
[0077] Figure 5 This is a schematic diagram of the structure of a power load control device provided in Embodiment 4 of the present invention. Figure 5 As shown, the device includes: a power generation determination module 310, a risk level determination module 320, and a load control module 330.
[0078] Among them, the power generation determination module 310 is used to obtain the predicted power generation corresponding to the target distributed power source and to collect the actual power generation corresponding to the target distributed power source.
[0079] The risk level determination module 320 is used to determine the risk level corresponding to the target distributed power source based on the predicted power generation and the actual power generation; wherein, the risk level includes a high risk level or a normal risk level;
[0080] The load regulation module 330 is used to regulate the load of the target distributed power source according to the target load control method corresponding to the risk level, so as to make the target distributed power source achieve a power supply balance state; wherein, the target load control method includes the load management system control method or the load terminal control method.
[0081] The technical solution of this embodiment obtains the predicted power generation corresponding to the target distributed power source and collects the actual power generation corresponding to the target distributed power source. The predicted power generation corresponding to the target distributed power source is determined through meteorological forecast data, and the actual power generation corresponding to the target distributed power source is collected based on power acquisition equipment. The risk level corresponding to the target distributed power source is determined based on the predicted power generation and the actual power generation. Based on the predicted power generation and the actual power generation, the risk level corresponding to the target distributed power source is determined. The risk level is further determined based on the relationship between the difference in available power and the first preset power difference and the second preset power difference.
