Abstract

Abstract:

Based on the controllability of electric vehicles in time and mobility in space, it can guide the charging of electric vehicles(EV) when the output of new energy is relatively high, and put forward solutions to the power grid fluctuation caused by intermittent renewable energy. The time energy characteristics of EV charging behavior are analyzed by using the correlation model based on Copula function, and the correlation of charging behavior parameters is verified. The collaborative planning of CSDG and distribution network with distributed generation is studied, and a collaborative planning model of CSDG and distribution network based on two-stage optimization is proposed. On the basis of example analysis, the corresponding reference suggestions for the construction of charging facilities are put forward.

Key words: distributed generation, charging facilities, temporal and spatial characteristics, collaborative planning
