Research On Comprehensive Optimal Pricing Strategy Of Electricity-transportation Interconnection System

Today,global energy and environmental problems are becoming more and more serious,and the emergence of electric vehicles is essential to promote the development of new energy.In the context of the Internet of Energy,the electric-transport interconnection system with electric vehicles as the link guides the travel mode of electric vehicle users by optimizing the electricity price strategy,thereby affecting the coordinated operation of the interconnected system.Aiming at the problem of comprehensive optimization pricing strategy of the electricity-transport interconnection system,this paper proposes two different pricing models.Pricing strategy model.The second is to conduct a system-level study on the power grid and transportation network,and propose an optimal node marginal price strategy model for the electricity-transport interconnection system.The main research contents are as follows:Firstly,analyze the operation mechanism of each component in the electric-transportation interconnection system.It mainly includes the traffic system flow allocation model and its classification mechanism;the application of the game competition mechanism in the study of the electric-transport interconnection system.Each participant in the interconnected system has game competition in order to achieve its own maximum benefit;the optimal power flow model of the power system is interconnected The system comprehensively optimizes the application of pricing strategies.Secondly,the interaction between the participants in the electricity-transport interconnection system is studied,and a fast charging station retailer non-cooperative game pricing strategy model is proposed,while considering the revenue sharing mechanism constraints of the power supply chain system and the user equilibrium transportation of the transportation system Distribution constraints.Newton-type iterative algorithm is used to solve the model.Simulation examples verify the effectiveness of the proposed non-cooperative game pricing strategy model in realizing multi-party interest balance under the guidance of fast charging stations in an electric-transport interconnection system.Finally,the system-level study of the power grid and transportation network in the electricity-transport interconnection system is conducted to achieve the minimum operating cost of the interconnection system.Based on the established equilibrium model of traffic users,the optimal power flow model of the distribution network is considered to establish the optimal node marginal pricing strategy model of the electric-transport interconnection system.Using the optimal response algorithm,iteratively solves the traffic allocation problem and the optimal power flow problem to make the interconnected system reach equilibrium,and obtain the optimal power price of the node,the optimal output of the unit,and the optimal traffic flow allocation.Give example simulation to verify the accuracy of the proposed model and method.
