Optimal Capacity Allocation Method of Electric Vehicle Charging Station for Micro-grid with PV,Wind Turbine,Diesel Generation and Storage Batteries

The hybrid charging station model with multiple complementary energy sources is one of the effective ways to solve the problem of island electric vehicle charging.According to the characteristics of energy structure in the island area,the power distribution scheme considering the investment and operation cost and renewable energy utilization rate was proposed.The mathematical model was established with the constraint conditions of oil generator power,battery power,wind power,photovoltaic power and power balance of each part of the system.Nondominated sorting genetic algorithms-II(NSGA-II)with elite strategy was used to solve the model.Combining with a specific example,the Pareto optimal solution was obtained.Several groups of typical optimal dispatching schemes were selected to conduct power balance analysis and verified the validity of the established mathematical model,so as to provide theoretical basis and technical support for the construction and operation management of multi-energy compound electric vehicle charging station.
