Electric power traffic coupling system coordination game scheduling method based on EV vehicle owner willingness

Abstract

The invention provides an electric power traffic coupling system coordination game scheduling method based on EV vehicle owner willingness, and the method comprises the steps: (1), building a trafficnetwork model which comprises a traffic network topology model built based on a graph theory and an EV vehicle owner charging behavior model; (2) establishing a double-layer coordination game scheduling model of the power traffic coupling network, establishing an optimization model of an upper-layer power network by taking the lowest power distribution cost as an optimization target and considering network constraints, and establishing a non-cooperative game model of each charging station in a lower-layer traffic network by taking self-income maximization as a target; (3) solving the double-layer optimization model, solving the optimal power flow problem of the upper-layer power grid by adopting a second-order cone programming method, obtaining the node electricity price of the power gridby adopting a power flow tracking method, solving the non-cooperative game problem of the charging station in the lower-layer traffic network by adopting a greedy algorithm, and alternately iteratingoptimization variables of upper and lower-layer sub-problems until the problem converges, and and achieving unified scheduling and optimized operation of the system.

Description

technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to a coordination game scheduling method for electric traffic coupling systems based on the will of EV vehicle owners. Background technique [0002] In order to reduce dependence on fossil energy that is about to be exhausted and reduce greenhouse gas emissions, electrification in the field of transportation has received policy support from various countries and has become a research hotspot in recent years. In 2017, the UK government announced it would ban the sale of new petrol and diesel cars by 2040. In recent years, Norway has had the highest penetration rate of electric vehicles (EVs) in the world, accounting for 48% of new car sales in the first quarter of 2019. The United States, particularly California, is actively developing incentives to increase the market share of electric vehicles and promote investment in charging infrastructure. Some As...
