Optimization Strategy of Electric Vehicle Charging Based on Electricity Price Demand Response

摘要

With the rapid development of electric-vehicles at home and abroad, as an electric load, electric-vehicles have an increasing impact on the power grid. Therefore, it is of great significance to study the charging optimization strategies of electric vehicles. This paper proposes an electric vehicle charging optimization strategy based on electricity price demand response. First, based on the driving characteristics of electric vehicles, the load model of electric vehicles in disordered charging mode is established. Then, considering the real-time electricity price, a multi objective charge-discharge model of electric vehicles under different weight combination modes is established. Finally, through a comparative example, the charging and discharging schemes of electric vehicles in different scenarios are analyzed and compared, and the effectiveness of the multi objective optimal control strategy for electric vehicles proposed in this paper is verified, which is conducive to coordinating the impact of load fluctuation regulation on consumer interests, to achieve optimization of multi-objective cars.
