Optimization of Spot Power Price in Coordinated Fast Charging Model of Electric Vehicles

Abstract

A real-time mechanism as a level of electricity price is proposed to dispatch electric vehicle fast charging load. Considering the peak load shifting effect of grid, the benefit of charging station and the desire of customer, the mathematics model is built. And a genetic algorithm is used to solve this problem. Finally, a simulation based on an areas predicted data of year 2020 is made to show that the proposed method can lower the peak-valley difference, promise charging station benefit as well as meet customers desire, and achieve a win-win result.
