Research On Optimal Configuration And Planning Of Electric Vehicle Charging Stations Considering Multi-energy Complementarity

The environmental benefits of distributed energy and electric vehicles are obvious,and a new model of integration of new energy and electric vehicles is proposed,that is,the electric vehicle charging station with wind and solar energy storage.In this paper,the multi energy complementary optimal configuration and the location and capacity planning of EV charging stations are studied.The research contents are as follows:(1)The stochastic volatility of wind and solar resources output is studied,and HOMER software is used to simulate wind and solar power generation curves.Based on the typical structure of multi-energy complementary microgrid,the structure and operation mode of electric vehicle charging station considering multi-energy complementarity are studied.According to the charging characteristics of electric vehicle users,the distribution of electric vehicle charging demand in the urban transportation network is studied.(2)Aiming at the electric vehicle charging station with distributed power supply,a multi-energy complementary optimal allocation model considering the construction cost of charging station and the utilization rate of wind and solar energy is constructed.An energy exchange strategy considering the economic benefits of charging station is proposed,and the model is solved by using the improved multi-objective group search algorithm.(3)Proposed a charging station planning model that takes into account the charging station construction cost and the user's overall charging cost;the weighted Voronoi diagram is used to implement the site decision,and the charging station queuing model is the capacity constraint.An improved simulated annealing particle swarm optimization algorithm is used to solve the optimal layout model of electric vehicle charging stations.At the new site,the proposed multi-energy complementary optimization configuration model is used to solve the multi-energy complementary electric vehicle charging station optimization configuration results.Finally,based on the developed Foshan electric vehicle intelligent guidance and charging station planning simulation platform,the planning effect is displayed.The analysis results show that the proposed planning method for multi-energy complementary electric vehicle charging stations has certain guiding significance for the city's future charging facilities.
