Research On Coordination And Scheduling Of Electric-Hydrogen Vehicle Charging And Discharging Based On Price Game

In recent years,the shortage of fossil energy and environmental issues have become increasingly serious,making the development of clean energy vehicles more and more attention.Electric vehicles(EV)have already been widely used in cities.At the same time,the development of hydrogen vehicles(HV)has gradually taken shape,and the penetration rate in cities has continued to increase.However,the integration of large-scale electric vehicles and hydrogen vehicles(collectively referred to as electric-hydrogen vehicles,EV-HV)into cities has made the regulation of urban multi-energy systems more complicated,and also brought huge challenges to the stability of the power grid.However,because the EV-HV has the characteristics of charging and discharging energy,it can be used as a flexible adjustment resource,and the above problems can be solved through reasonable coordination and scheduling.Therefore,this paper studies the charging and discharging characteristics of EV-HV based on the price game model,and uses this as a basis to study how to coordinate the charging and discharging of EV-HV to participate in the coordinated and optimized dispatch of urban multi-energy systems.The specific research content is as follows:The load characteristics of EV-HV were analyzed,and the charging and discharging energy model of EV-HV was established.At the same time,the urban multi-energy system is connected to the EV-HV and the multi-energy system framework structure of the emerging subject,and the distributed power sources,energy conversion equipment,and storage equipment in the multi-energy system are modeled,and wind power generation is established.,Photovoltaic power generation,gas turbine,electricity storage,hydrogen storage and other models,lay the model foundation for the later research on the optimal dispatch of multi-energy systems based on EV-HV charging and discharging.The relationship between supply and demand balance after EV-HV is connected to the urban multi-energy system is studied.Based on the characteristics of urban energy supply and demand,an EV with electric hydrogen energy grid company as the main party of the game and EV-HV users as the game follower is established.-HV charging and discharging energy price game model.The game model aims to optimize the charging and discharging cost of EV-HV users to minimize the cost,using particle swarm optimization algorithm to solve its Nash equilibrium solution,and obtain the relationship between the charging and discharging energy price and the amount of adjustment that EV-HV can participate in when the game is in equilibrium.The effectiveness of the model is verified by simulation examples,and it is proved that using the characteristics of EV-HV charging and discharging can play the role of peak shaving and valley filling.At the same time,three different models of profit models have been established and analyzed through simulation.The profitability of different types of cars at each moment.Based on the research of EV-HV charging and discharging characteristics of price game,the optimal dispatch of multi-energy systems at this time is studied.A dual objective function model with the lowest operating cost of the multi-energy system and the smallest environmental pollution control cost was established.The dual objective function was processed by the analytic hierarchy process,and the beetle-particle swarm hybrid search algorithm(BAS-PSO)was used for this city.The energy system coordinated dispatch model is solved,and the system operation cost and the output of each unit in the two scenarios of the system without EV-HV and EV-HV are analyzed by simulation,and the optimal output of EV-HV after coordination and optimization is obtained;the final analysis The system operating cost and pollution control cost under different weights are analyzed,and the total cost of the system is analyzed.
