The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0024] Example 1 Reference Figure 1 The first embodiment of the present invention provides a regional power peak-shaving resource coordination method based on cloud computing.
[0025] Step 1: A regional power consumption prediction model based on support vector machine (SVR) is constructed to predict regional power consumption in the future time period based on the historical power consumption data of the region.
[0026] The construction of the regional power consumption prediction model of the support vector machine SVR includes: using the mathematical model of the support vector machine SVR to predict the regional power consumption, setting the regional In time The power consumption is , the historical electricity consumption data is ,in is the input feature, n is the number of historical electricity consumption data, and the mathematical model of the support vector machine SVR is as follows: ; ; in, is the weight vector, For paranoid items, and Used to define the regression plane, and is the slack variable, is the maximum regression deviation, It is used to control the smoothness of the regression plane; is the input mapping function; is the transpose of the weight vector; is the regularization term in the support vector machine SVR objective function, is the time of the nth historical electricity consumption data.
[0027] Regional power consumption prediction model based on support vector machine SVR: ; Where N is the total number of regions, and is the Lagrange multiplier, is the kernel function, It is a region The power consumption predicted at time t. The regional power consumption prediction model based on support vector machine (SVR) can be used to predict the power consumption of the region by combining the input features of the future time period of the region.
[0028] The present invention adopts the support vector machine regression model SVR to predict regional electric power consumption. The SVR model has good generalization ability and nonlinear fitting ability, can effectively capture the changing trend of electric power consumption, and provide an important basis for subsequent power peak demand analysis.
[0029] Step 2: Based on the regional power consumption forecast results and the regional power generation power and power storage capacity, calculate the regional power peak demand, the power peak demand includes the remaining power peak time and the power peak power demand, and based on the regional power peak demand calculation results, divide the power consumption area in the future time period into power peak demand area, stable power consumption area and power surplus area.
[0030] Calculation area The peak load demand of electricity is At current time To the future time Predicted peak power consumption Larger than area Power generation in When , the calculation area At current time Predicted electricity consumption at future time point t : ; If the area At current time Predicted electricity consumption at future time point t Larger than area The storage capacity When the sum of the power generation is: , then the region There is a demand for power peak load regulation. Mark as power peak demand area and calculate the area Remaining power peak-shaving time : ; in, is the storage capacity of region i, It is a region At current time The power consumption at each moment.
[0031] The remaining power peak load time It is a region The remaining time during which the power generation and storage can guarantee stable power consumption in the region is required to be during the remaining power peak load time. Internal area Transmit power at a rate greater than the peak power demand, otherwise the region During the remaining power peak load period It will not be possible to ensure stable electricity supply in the area.
[0032] Then the area The peak power demand of : .
[0033] When the area At current time To the future time Predicted peak power consumption Larger than area Power generation in When and area At current time Predicted electricity consumption at future time point t Less than or equal to area The storage capacity When the sum of the power generation is: ; The power generation and storage within region i can meet its own electricity demand, and region i is divided into a stable power consumption area.
[0034] When the area At current time To the future time Predicted peak power consumption within Always smaller than area Power generation in Time, area At current time To the future time The power generated within the area is greater than the power consumed. There is no peak load demand and the area Divided into power surplus areas.
[0035] Based on the prediction results of regional power consumption, combined with the regional power generation and storage information, the regional power peak-shaving demand can be analyzed and calculated. Specifically, when the predicted regional power consumption peak exceeds the regional power generation, it means that the region may face the problem of insufficient power supply; at this time, it is necessary to calculate the predicted power consumption of the region in the future time period and compare it with the regional power storage and power generation; if the predicted power consumption is greater than the sum of the power storage and power generation, it indicates that there is a power peak-shaving demand in the region.
[0036] For areas with power peak-shaving needs, it is necessary to further calculate the remaining power peak-shaving time, that is, the remaining time that the region's own power generation and storage can maintain stable power consumption. The calculation of this time takes into account the region's storage capacity, predicted power consumption and real-time power consumption. During the remaining power peak-shaving time, sufficient electricity needs to be transferred in from other regions to meet the region's power demand.
[0037] In addition to the peak demand areas, it is also necessary to identify stable power consumption areas and power redundancy areas; the characteristic of stable power consumption areas is that the predicted power consumption is less than or equal to the sum of power storage and power generation, indicating that the power supply in the area can meet the power demand. In the power redundancy area, the predicted power consumption is always less than the power generation, indicating that there is a power surplus in the area, which can be used as a supplier of peak power.
[0038] Step 3: construct a regional power peak-shaving resource pool based on regional power peak-shaving resources, wherein the regional power peak-shaving resources include power generating sets and power storage equipment in the region.
[0039] There is There is a demand for peak power regulation in the first region. There is a power surplus in the regions, and the current time To the future time In the segment, the power surplus area The power available for peak load regulation Surplus power of the generator set And the output power of the storage device sum: ; ; Calculate the power available for peak load regulation in all power surplus areas : ; in, Indicates the number of regions with power surplus; the power available for power peak regulation in all power surplus regions Form a regional power peak-shaving resource pool.
[0040] In order to achieve inter-regional power peak regulation, it is necessary to build a regional power peak regulation resource pool; the resource pool includes the generators and power storage equipment in each region. For regions with power redundancy, their surplus power generation and output power of power storage equipment can be included in the resource pool as power resources available for peak regulation; through the management and scheduling of the resource pool, the optimal allocation of power resources between regions can be achieved, and the overall peak regulation capacity of the power system can be improved.
[0041] Step 4: Based on the inter-regional power transmission paths and power peak-shaving resource reserves, and taking into account the inter-regional power transmission losses, a regional power peak-shaving resource coordinated scheduling model is constructed with the remaining power peak-shaving time and power peak-shaving power demand as constraints, and the power peak-shaving response power of the power surplus area to the power peak-shaving demand area is calculated.
[0042] Assume that the set of power surplus areas is A, and the set of power peak demand areas is B, then the power peak demand areas , power surplus area , define the power variable It is the power peak-shaving response power of power surplus area j to power peak-shaving demand area i.
[0043] The objective function of minimizing the power peak-shaving response power of the power surplus area to the power peak-shaving demand area is constructed as a regional power peak-shaving resource coordinated scheduling model to calculate the power peak-shaving response power of a single power surplus area to a single power peak-shaving demand area. : ; Calculation of power peak load response power in regional power peak load resource coordinated dispatch model based on constraint conditions .
[0044] The constraint condition includes that the peak-shaving power response power of the jth region in the regional peak-shaving resource pool does not exceed the peak-shaving power available for the jth region. ,Right now .
[0045] The constraint condition also includes that the sum of the power peak load response power obtained by the power peak load demand area i from the regional power peak load resource pool is , considering the power transmission efficiency , ;and .
[0046] The constraints also include considering the transmission time from the power surplus area to the power peak demand area. ,but: ; According to the regional power peak load resource coordinated dispatch model, the power peak load response power of a single power surplus area to a single power peak load demand area is calculated. .
[0047] On the basis of constructing a regional power peak-shaving resource pool, it is necessary to further establish a coordinated dispatch model for regional power peak-shaving resources; this model comprehensively considers factors such as inter-regional power transmission paths, power peak-shaving resource reserves, and power transmission losses. Taking the remaining power peak-shaving time and power peak-shaving power demand of the area with power peak-shaving demand as constraints, through mathematical modeling and optimization solution, the optimal response strategy for the power redundant area to provide power support to the power peak-shaving demand area can be calculated, that is, the power peak-shaving response power of each power redundant area to each power peak-shaving demand area. The goal of the coordinated dispatch model is to minimize the total amount of power peak-shaving response in the power redundant area as much as possible while ensuring the stability of power consumption in the power peak-shaving demand area, so as to achieve the optimal allocation of power resources between regions.
[0048] Step 5: The power surplus area dispatches power to the area with power peak load demand according to the allocated power peak load response power.
[0049] The power peak-shaving response power of the power surplus area to the power peak-shaving demand area is calculated , power surplus areas respond to power peak load The peak-shaving response is carried out for the area with peak power demand. After time t is reached, the regional power consumption is predicted again and the dispatch response power is calculated to ensure stable power consumption in the region.
[0050] According to the calculation results of the regional power peak-shaving resource coordinated dispatching model, the power redundant area needs to dispatch power to the power peak-shaving demand area according to the allocated power peak-shaving response power; comprehensively consider factors such as the real-time operating status of the power grid and the working status of power equipment to ensure the reliability and safety of power dispatching.
[0051] Through reasonable power dispatching, the power supply pressure in the power peak demand area can be effectively alleviated to ensure the normal power demand of users in the region; at the same time, the power peak response in the power redundant area can also help improve the overall operating efficiency of the power system and promote the optimal allocation of power resources among regions.

[0054] The power consumption prediction module adopts a regional power consumption prediction model constructed by a support vector machine (SVR) to predict regional power consumption in future time periods based on historical power consumption data of the region.
[0055] The peak-shaving demand calculation module calculates the regional power peak-shaving demand based on the regional power consumption prediction results and the regional power generation power and power storage capacity. The power peak-shaving demand includes the remaining power peak-shaving time and the power peak-shaving power demand. Based on the regional power peak-shaving demand calculation results, the power consumption area in the future time period is divided into power peak-shaving demand area, stable power consumption area and power surplus area.
