[0033] Embodiment 1

[0034] Figure 1 This is a flow chart of a power system control method provided in the first embodiment of the present invention. This embodiment is applicable to the case of power system control. The method can be executed by a power system control device. The power system control device can be implemented in the form of hardware and / or software. The power system control device can be configured in electronic devices such as computers and control devices. Figure 1 As shown, the method includes:

[0035] S110, determining the estimated frequency data of each branch road in the target power system during the current period, and sending the estimated frequency data of each branch road during the current period to the corresponding branch road, so that the corresponding branch road is controlled according to the estimated frequency data.

[0036] Among them, the target power system refers to the power system to be regulated, including at least one branch road. Each day can be divided into multiple time periods. Preferably, each hour is regarded as a time period. Each day can be divided into 24 time periods, and the power system in each time period is regulated in turn. The estimated frequency data can be specifically understood as data for estimating the current or future frequency of each branch of the power system, which can be determined by a frequency estimation model or a preset frequency estimation algorithm. The estimated frequency data for each time period of the next day can be determined in advance and stored in a preset storage space. When the power system is regulated in the corresponding time period, the estimated frequency data for the corresponding time period can be retrieved.

[0037] Specifically, when it is detected that the power system needs to be regulated, or when the power system reaches the regulation time based on the preset regulation cycle, the estimated frequency data of each branch road in the current period can be read from the preset target storage space, or it can be calculated in real time through a preset algorithm or frequency estimation model, which can be set according to actual conditions. The acquired estimated frequency data of each branch road in the current period is sent to the corresponding branch road, and the control device set on each branch road performs frequency regulation according to the corresponding estimated frequency data.

[0038] In this embodiment, the frequency control of each branch is performed by determining the estimated frequency data of each branch so that the frequency data of each branch approaches the corresponding estimated frequency data, thereby ensuring that the frequency data of each branch meets the frequency control requirements and improving the stability of the power system.

[0039] Optionally, determining the estimated frequency data of the current time period for each branch road in the target power system includes: obtaining historical power consumption information of each branch road in the target power system, wherein the historical power consumption information includes historical frequency data and timestamps; for any historical time period, filtering out the historical frequency data of each branch road in at least one historical time period from the historical power consumption information based on the timestamp, and determining the average frequency data of each branch road in the historical time period based on the historical frequency data of each branch road in at least one historical time period; determining the frequency correction data of each branch road in the historical time period based on the average frequency data of each branch road in the historical time period and the frequency data of the corresponding historical time period of the previous day of the current time period; determining the estimated frequency data of the corresponding time period of the current day for each branch road based on the frequency correction data of each branch road in the historical time period and the daily average frequency data of the corresponding branch road; selecting the estimated frequency data corresponding to the time period matching the current time period of each branch road, and setting the estimated frequency data matched to each branch road as the estimated frequency data of the current time period of the corresponding branch road.

[0040] Specifically, the historical power consumption information of the target power system is retrieved from the historical data storage space or server, and the power consumption information includes but is not limited to historical frequency data and timestamps. The historical frequency data of each branch in at least one historical period is filtered out from the historical power consumption information according to the timestamp, and the historical power consumption information is statistically analyzed. For each historical period, the historical frequency data of the historical period of each day is extracted to determine the average frequency data of each branch in the historical period. For the average frequency data of the kth period of the i-th branch, the average frequency data of the kth period is obtained. The calculation formula is as follows:

[0041]

[0042] Among them, i is the branch number, k is the time period number, z represents the number of days of historical data, and n is the maximum value of days, which can be 1, 2, 3, ..., n, and can be set according to the actual situation. is the frequency data of the kth period on the zth day.

[0043] The average frequency of consumption of each branch road in each time period represents the power consumption trend of each branch road in the corresponding time period. In order to evaluate the estimated frequency data of each time period of the day, it is necessary to consider the frequency data of the corresponding time period in the previous day or the previous few days. The difference between the average frequency data of each branch road in the historical time period and the frequency data of the corresponding historical time period of the day before the current time period can be calculated, and the difference is set as the frequency correction data of each branch road in the historical time period. Then, the sum of the frequency correction data and the average frequency data of the daily consumption of the corresponding branch road is used as the estimated frequency data of the corresponding time period of the corresponding branch road, so as to obtain the estimated frequency data of each branch road in each time period of the current day. By matching the current time period with the estimated frequency data of each branch road in each time period of the current day, the estimated frequency data corresponding to the time period matching the current time period of each branch road is determined, that is, the estimated frequency data of the current time period of each branch road is obtained.

[0044] S120. For each branch road, obtain the real-time load frequency data collected after the branch road is frequency-controlled according to the corresponding estimated frequency data, and obtain the time period information of the peak and valley types of electricity consumption of the branch road, and determine the load power consumption information of the branch road based on the real-time load frequency data, the estimated frequency data and the time period information of the peak and valley types of electricity consumption.

[0045] Among them, the frequency data on the load side is directly related to the stability of the power system, the quality of electric energy and the operating efficiency of the equipment. The load change will cause the corresponding change of the frequency. This change needs to be maintained by the frequency adjustment of the power system. Therefore, it is necessary to monitor the load frequency data in real time. Real-time collection can be performed through pre-installed frequency data acquisition equipment. The peak and valley type of electricity consumption can be specifically understood as a power price system that characterizes the distribution of power consumption periods, and can divide 24 hours a day into multiple periods such as peak, flat, and valley according to the load changes of the power grid, and formulate different electricity price levels for each period. This system is intended to encourage electricity users to reasonably arrange electricity consumption time, cut peaks and fill valleys, and improve the utilization efficiency of power resources. In this embodiment, the electricity consumption during the peak and valley periods of electricity consumption is specifically considered, and the peak and valley periods of electricity consumption of each branch can be determined by statistical analysis based on historical electricity consumption information. The load power consumption information can be specifically understood as information used to regulate each branch in the power system, which can be determined according to the preset load power consumption information determination strategy. The load power consumption information includes but is not limited to load proportion data and load power consumption period.

[0046] Specifically, after each branch road is regulated according to the corresponding estimated frequency data, the real-time load frequency data of each branch road is collected in real time through the frequency data collection equipment, and each branch road uploads the collected real-time load frequency data to the load analysis module. The load analysis module analyzes the real-time load frequency data and obtains the time period information of the peak and valley types of electricity consumption of each branch road at the same time. The load analysis module analyzes the real-time load frequency data, the time period information of the peak and valley types of electricity consumption and the estimated frequency data to determine the load power consumption information of the branch road.

[0047] Optionally, the method also includes: determining the frequency adjustment parameters of each branch road based on the estimated frequency data of the current time period of each branch road and the corresponding real-time load frequency data; adjusting the estimated frequency data of the next time period of the corresponding branch road based on the frequency adjustment parameters of each branch road, and obtaining the adjusted estimated frequency data of the next time period of each branch road, so as to control each branch road to perform regulation based on the adjusted estimated frequency data of the next time period.

[0048] Specifically, the estimated frequency data of the current time period of each branch road is compared with the corresponding real-time load frequency data to determine whether the estimated frequency data of the current time period and the corresponding real-time frequency data are the same. If they are not the same, the difference between the two is determined to obtain the frequency adjustment parameters of each branch road, and the estimated frequency data of the next time period of the corresponding branch road is adjusted based on the frequency adjustment parameters of each branch road to obtain the adjusted estimated frequency data of the next time period of each branch road, which is used for frequency control of each branch road in the next time period.

[0049] It is understandable that when the frequency adjustment instruction is issued to each branch road, each branch road has different demands for electric energy. Therefore, the frequency consumed by some branches does not reach the estimated frequency at that moment, while the frequency consumed by some branches exceeds the estimated frequency at that moment. Therefore, it is necessary to obtain the real-time load frequency data of each branch road, and to correct the estimated frequency in the next time period to increase the load proportion of branches with excessive frequency consumption in the energy and power system, and reduce the load proportion of branches that have not reached the estimated frequency in the energy and power system.

[0050] In this embodiment, the real-time load frequency data of each branch road is compared with the estimated frequency data of the current time period to determine whether to adjust the estimated frequency data of each branch road for the next time period. If adjustment is required, the frequency adjustment parameters are determined by the estimated frequency data of the current time period of each branch road and the corresponding real-time load frequency data, so as to adjust the estimated frequency data of the next time period of each branch road in real time, so as to meet the frequency control needs of each branch road in real time, improve the accuracy and real-time control of each branch road of the power system, and improve the real-time control and stability of the power system.

[0051] S130: Regulate and control the target power system based on the load power consumption information of each branch.

[0052] Specifically, when the load power usage information of each branch is obtained, one or more items of the load power usage information are used to generate corresponding control instructions for controlling each branch of the target power system.

[0053] The technical solution of this embodiment determines the estimated frequency data of the current time period of each branch road in the target power system, and sends the estimated frequency data of the current time period of each branch road to the corresponding branch road, so that the corresponding branch road is regulated according to the estimated frequency data; for each branch road, the real-time load frequency data collected after the branch road is frequency regulated according to the corresponding estimated frequency data is obtained, and the time period information of the peak and valley type of electricity consumption of the branch road is obtained, and the load power consumption information of the branch road is determined based on the real-time load frequency data, the estimated frequency data and the time period information of the peak and valley type of electricity consumption; the target power system is regulated based on the load power consumption information of each branch road. This solution regulates each branch road through the estimated frequency data, and then determines the load power consumption information of the branch road based on the real-time load frequency data, the estimated frequency data and the time period information of the peak and valley type of electricity consumption of the branch road, which is used to regulate each branch of the target power system, solve the problems of low utilization and poor stability of the power system, and improve the accuracy, stability and utilization of power system regulation.

[0054] Embodiment 2

[0055] Figure 2 It is a flow chart of a power system control method provided in the second embodiment of the present invention, and this embodiment is a further optimization of the method of the above embodiment. Optionally, the initial load share data of the branch road is adjusted based on the real-time load frequency data and the estimated frequency data to obtain the load share data of the branch road; and / or, the load power consumption time period of the branch road is determined based on the time period information corresponding to the peak and valley type of power consumption of the branch road and the time period information corresponding to the real-time load frequency data; based on the load share data in the load power consumption information of each branch road, the load share data of the corresponding branch road is adjusted to control the real-time load frequency data of each branch road in the target power system to tend to the corresponding estimated frequency data; and / or, based on the load power consumption time period in the load power consumption information of each branch road, the load power consumption time period of the corresponding branch road is set to control each branch road in the target power system to consume power in the corresponding load power consumption time period. Figure 2 As shown, the method includes:

[0056] S210, determining the estimated frequency data of each branch road in the target power system during the current period, and sending the estimated frequency data of each branch road during the current period to the corresponding branch road, so that the corresponding branch road is regulated according to the estimated frequency data.

[0057] S220. For each branch road, obtain real-time load frequency data collected after the branch road performs frequency control according to the corresponding estimated frequency data, and obtain time period information of the peak and valley type of electricity consumption of the branch road.

[0058] S230. Adjust the initial load share data of the branch road based on the real-time load frequency data and the estimated frequency data to obtain the load share data of the branch road; and / or determine the load power consumption time period of the branch road based on the time period information corresponding to the peak and valley type of power consumption of the branch road and the time period information corresponding to the real-time load frequency data.

[0059] Among them, the load share data of the branch road can be specifically understood as the share of the branch road load in the total load of the target power system. The initial load share can be specifically understood as a preset initial value, which can be predicted through the preset load curve of each branch road to determine the initial load share of the current period, or it can be determined based on the ratio of the load data of each branch road in the historical power consumption information to the total load data of the power system. The initial load share determined by the historical power consumption information can be pre-stored in a preset storage space. When applied, it can be directly read from the preset storage space according to the current period to shorten the acquisition time of the load share data and improve the rapidity of determining the load share data.

[0060] Specifically, according to the current time period of each branch, the corresponding initial load share is obtained from the preset storage space, and the real-time load frequency data of each branch is compared with the corresponding estimated frequency data. When the real-time load frequency data is lower than the estimated frequency data, it indicates the frequency angle of real-time consumption, and then the corresponding load share data needs to be reduced, that is, the corresponding initial load share needs to be reduced. In addition, the time period information corresponding to the peak and valley type of electricity consumption of each branch is obtained, and it is determined whether the time period information of the real-time load frequency data of each branch segment matches the time period information corresponding to the corresponding peak and valley type of electricity consumption. When the time period information of the real-time load frequency data of each branch segment coincides with the time period information corresponding to the peak of electricity consumption, the load power consumption time period can be adjusted to the time period corresponding to the valley of electricity consumption. When the time period information of the real-time load frequency data of each branch segment coincides with the time period information corresponding to the valley of electricity consumption, there is no need to adjust the power consumption time period of the branch road, so as to realize the reasonable arrangement of power consumption time, peak shaving and valley filling, and improve the utilization efficiency of power resources. It should be noted that one or more of the methods for determining the load share data and the load power consumption time period are automatically set according to the actual situation.

[0061] Optionally, the initial load share data of the branch road is adjusted based on the real-time load frequency data and the estimated frequency data to obtain the load share data of the branch road, including: calculating the difference data between the real-time load frequency data and the estimated frequency data of the branch road, matching the difference data based on a preset mapping relationship between the difference data and the load share adjustment data, and determining the load share adjustment data of the branch road; adjusting the load share data of the branch road based on the load share adjustment data of the branch road to obtain the adjusted load share data of the branch road.

[0062] Specifically, the mapping relationship between the preset difference data and the load share adjustment data is called, and the difference data between the real-time load frequency data and the estimated frequency data of the branch road is calculated. The difference data is matched in the preset mapping relationship between the difference data and the load share adjustment data to determine the load share adjustment data that matches the difference data. It should be noted that the load share adjustment data is positive and negative data. The load share adjustment data of the branch road and the load share data of the branch road are summed to obtain the adjusted load share data of the branch road.

[0063] It should be noted that obtaining the proportion of each branch road load in the total load of the energy and power system is to allow the power system to allocate power generation equipment and power supply equipment suitable for each branch road in advance, so as to avoid the inability to fully utilize the existing power generation equipment and power supply equipment. For example, a branch road needed to consume 1 million kilowatts at 10 am yesterday, and the power system allocated a batch of power generation equipment with a frequency of 5 million kilowatts to the branch road. This will cause the problem of not being able to fully utilize the power generation equipment. Therefore, in order to avoid this situation, it is necessary to estimate in advance the proportion of each branch road load in the total load of the energy and power system.

[0064] Optionally, the electricity consumption peak and valley types include a peak electricity consumption type and a valley electricity consumption type; the load electricity consumption time period of the branch road is determined based on the time period information corresponding to the peak and valley electricity consumption type of the branch road and the time period information corresponding to the real-time load frequency data, including: judging whether the time period information corresponding to the real-time load frequency data overlaps with the time period information of the peak and valley electricity consumption type of the branch road; if the time period information corresponding to the real-time load frequency data overlaps with the time period information of the peak and valley electricity consumption type of the branch road, setting the time period corresponding to the valley electricity consumption type of the branch road as the load electricity consumption time period of the branch road.

[0065] In this embodiment, the peak and valley types of electricity consumption of each branch road are specifically considered. By judging whether the time period information corresponding to the real-time load frequency data coincides with the time period information of the peak and valley types of electricity consumption of the branch road, it is specifically judged whether the time period information of the real-time load frequency data of each branch segment matches the time period information corresponding to the corresponding peak and valley types of electricity consumption. When the time period information of the real-time load frequency data of each branch segment coincides with the time period information corresponding to the peak electricity consumption, the load electricity consumption time period can be adjusted to the time period corresponding to the valley type of electricity consumption. When the time period information of the real-time load frequency data of each branch segment coincides with the time period information corresponding to the valley type of electricity consumption, there is no need to adjust the electricity consumption time period of the branch road.

[0066] S240. Adjust the load share data of the corresponding branch road based on the load share data in the load power consumption information of each branch road to control the real-time load frequency data of each branch road in the target power system to tend toward the corresponding estimated frequency data; and / or, set the load power consumption time period of the corresponding branch road based on the load power consumption time period in the load power consumption information of each branch road to control the power consumption of each branch road in the target power system during the corresponding load power consumption time period.
