Research on optimal capacity configuration method of PV-energy storage-charging integrated system

The development of electric vehicles plays an important role in promoting the double carbon goal.However,the large-scale electric vehicle load connected to the power grid will affect the safe operation of the power grid.The PV-energy storage-charging integrated system is a green and intelligent charging mode for the reason that it can use photovoltaic system.Therefore, how to configure the capacity of the photovoltaic and energy storage system, And the selection of capacity optimization method is very important for the construction and development of optical storage and charging integrated system. Firstly, a brief overview of the composition of the integrated optical storage and charging system and the development status of the integrated optical storage and charging charging station is giver, and the distribution of typical domestic integrated optical storage and charging system demonstration projects is listed. Then the influencing factors of electric vehicle charging load and the electric vehicle load forecasting method based on Monte Carlo method is analyzed. Finally, the advantages and disadvantages of several typical optimization algorithms applied to the system capacity configuration are compared,in order to provide reference for the scientific and reasonable configuration of the capacity of the integrated optical storage and charging system.
