Abstract

This application discloses a virtual power plant peak regulation control method and system for distributed charging piles. This method uses the virtual power plant technology to aggregate the charging piles into a whole, and controls the power of the charging piles through the virtual power plant, so as to more accurately match At the same time, by obtaining the peak-shaving demand of the charging pile in the next preset time period and the adjustment margin of the charging pile in the virtual power plant, the peak-shaving demand command is generated to meet the peak-shaving demand and adjustment margin, The power adjustment amount of the charging pile is determined by the adjustment margin and the peak shaving demand command, and the linear programming model of the virtual power plant is established with the goal of minimizing the power cost, which enhances the economics of the distributed charging pile participating in peak shaving, and meets the requirements of power distribution. It also improves the power supply reliability of charging piles, thereby reducing the demand for spinning reserve on the power generation side and minimizing the impact on the load side under the premise of ensuring the safety of the power grid.

Description

technical field [0001] The present application relates to the technical field of virtual power plant dispatching, in particular to a virtual power plant peak regulation control method and system for distributed charging piles. Background technique [0002] At present, with the rapid development of modern urban distribution network, the network structure tends to be complicated. With the continuous increase of urban electricity load and the increasing load demand of the distribution network, it is necessary to supplement the load deficit through the spinning reserve on the power generation side. , Moreover, it is difficult to meet the economic operation requirements of the distribution network. Reducing the load demand through the traditional load side will seriously affect the reliability of power supply. [0003] At the same time, with the gradual increase in the number of charging piles, the total load of this part has affected the reliability of power supply. Due to th...
