Research On The Control Strategy Of Electric Vehicle Shared Parking Space In Microgrid Environment

Sharing economy has triggered a series of revolutions in various industries,which improves the efficiency of asset utilization and reduces the redundancy of resources.Parking space sharing is a typical manifestation of sharing economy.With the rapid development of electric vehicle(EV),the problem of "difficult parking and charging" is gradually reflected,and parking space sharing is particularly important at this time.The sharing private parking space(SPPS)with EV charging capability brings a lot of storage resources with dynamic access behavior for the microgrid.To solve this problem,this paper proposes a market framework of EV and SPPS based on DSM(EVSPPS).This framework provides an opportunity for microgrid to participate in demand side management(DSM)using EV’s mobile storage devices.Microgrid optimizes the charging cost of EV by changing the charging and discharging behavior of EV,and the benefits are shared by microgrid and electric vehicle owners.This paper focuses on the research of the control strategy of the electric vehicles shared parking space to provide solutions for the new market framework.The main contents are as follows:First of all,combining the characteristics of EV energy storage and SPPS,a market framework of EVSPPS is proposed.The framework consists of two parts: EV’s demand side management and EVSPPS matching.Based on the market framework of electric vehicles and shared private parking spaces considering DSM,a matching model and DSM model are built.The DSM model optimizes the charging and discharging behavior of EV by combining the energy storage characteristics of EV’s battery,the initial electricity quantity and the time of entering and leaving the station;the matching model optimizes the charging and discharging behavior of EV by combining the time of entering and leaving the station and the parking fee of electric vehicle,as well as the idle time and rental fee of sharing private parking space.Secondly,it introduces the demand side management of electric vehicles,the control strategy of EV and SPPS matching.Two aspects of research work have been carried out: one is to develop evspps regulation and control strategy based on compensation matching mechanism from the perspective of microgrid benefits,taking the maximization of microgrid benefits as the objective function;the other is to considerthe benefits of microgrid and electric vehicle simultaneously,taking the satisfaction weighting coefficient of microgrid and electric vehicle as the objective function,adopting evspps regulation and control strategy based on improved ant colony algorithm.Finally,the research and verification work is carried out through the simulation and analysis of examples.Based on the market framework,this paper studies the control strategy of electric vehicle shared parking space in microgrid environment.The results show that the evspps control strategy based on compensation matching mechanism can make the microgrid gain better benefits in the market structure;with compensation matching mechanism can increase the EV parking opportunities;verify the feasibility of the new market structure.In addition,the EVSPPS control strategy based on the improved ant colony algorithm proposed in this paper can better meet the benefits of microgrid and electric vehicle.Through the case study,the feasibility of the market structure proposed in this paper is verified,and it brings convenience and benefits to microgrid,EV and SPPS.
