Cooperative interaction method and system for electric vehicle charging station and photovoltaic power station

Abstract

The invention relates to a cooperative interaction method and system for an electric vehicle charging station and a photovoltaic power station. The method comprises the following steps: acquiring nodepower information of each photovoltaic power station, a user power utilization terminal and an electric vehicle accessed to the electric vehicle charging station in an area; establishing an electricvehicle-photovoltaic power generation collaborative interaction dynamic planning model according to the acquired information, wherein the electric vehicle-photovoltaic power generation collaborative interaction dynamic planning model comprises an objective function for realizing minimum energy system load variance in the region and a corresponding constraint condition; solving the electric vehicle-photovoltaic power generation collaborative interaction dynamic planning model through a particle swarm optimization algorithm based on hybridization; and formulating an energy collaborative interaction strategy in the regional energy system according to the obtained optimal solution. Compared with the prior art, energy cooperative interaction between the photovoltaic power station and the electric vehicle charging station is achieved, stable operation of a regional energy system is ensured, and meanwhile environmental protection benefits are considered.

Description

technical field [0001] The invention relates to the field of coordinated control of regional energy sources, in particular to a method and system for collaborative interaction between an electric vehicle charging station and a photovoltaic power station. Background technique [0002] Ensuring the security of energy use and dealing with greenhouse gas emissions and pollution mainly caused by the extensive use of fossil energy has become the core goal of the energy development strategies of major countries in the world. At present, to promote the transformation of the energy system to a clean and low-carbon direction, how to solve the randomness and uncertainty brought by the access of renewable energy to the load of the traditional grid, and how to effectively stabilize the load fluctuation have become problems that need to be solved now. [0003] At the same time, electric vehicles are gradually being used in modern society on a large scale. The large-scale development of el...
