Abstract

The invention discloses a multi-objective optimization scheduling method for an electric vehicle charging station including a photovoltaic power generation system, and belongs to the technical field of smart power grids. Power purchase cost minimization and circulating electric quantity minimization of an energy storage system are used as objective functions, and a multi-objective optimization scheduling model of the electric vehicle charging station including the photovoltaic power generation system is built; the decision variable of the scheduling model and the constraint condition of the decision variable are determined; basic data are determined; solution is carried out through a multi-objective optimization algorithm to obtain a non-dominated solution leading surface, and then multiple Pareto optimal solutions are obtained; according to the low comprehensive cost of the main circulating electric quantity of the energy storage system and the power purchase cost, the charging station scheduling optimal scheme is selected at last. The multi-objective optimization scheduling method is suitable for the electric vehicle charging station including the photovoltaic power generation system of various cities with rich light sources; the scheduling scheme of the electric vehicle charging station including the photovoltaic power generation system is optimized; theoretical bases and technical supporting can be provided for the scheduling of the electric vehicle charging station including the photovoltaic power generation system; the operation economical efficiency of the charging station is improved.

Description

technical field [0001] The invention relates to a multi-objective optimal scheduling method for an electric vehicle charging station including a photovoltaic power generation system, and belongs to the technical field of smart grids. Background of the Invention [0002] With the widespread development of electric vehicles in countries around the world, the planning and construction of charging infrastructure has received more attention from the Chinese government. At present, the primary energy on the power generation side of my country's power system is still dominated by coal (accounting for about 75% to 80%). Electric vehicles are directly connected to the power grid for charging through the charging infrastructure. The actual indirect carbon emissions produced are less than those of traditional fuel vehicles. There is no obvious advantage, and it is difficult to reduce the dependence on fossil fuels. In this case, there are two ways to achieve low-carbon in the true sens...
