Abstract

The invention discloses a virtual power plant peak regulation control method and system for distributed charging piles. The method employs a virtual power plant technology to aggregate charging piles into a whole, carries out power control on the charging piles through a virtual power plant so as to precisely match the load demands of a power grid, generates a peak regulation demand instruction by obtaining the peak regulation demand quantity of the charging piles in the next preset time period and the regulation margin of the charging piles in the virtual power plant so as to meet the peak regulation demand quantity and the regulation margin, determines the power regulation quantity of the charging piles according to the regulation margin and the peak regulation demand instruction, and establishesthe linear programming model of the virtual power plant by using the minimum power cost as the target so as to enhance the economical efficiency of the distributed charging piles participating in peak regulation, meet the economic operation requirement of the power distribution network and improve the power supply reliability of the charging piles, so that on the premise that the safety of the power grid is guaranteed, the spinning reserve requirement on the power generation side is reduced, and the influence on the load side is minimized.

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...
