Research on Optimal Control System of Orderly Power Consumption in Station Area Based on V2G Technology

Aiming at the problem of load fluctuation caused by disordered charging and discharging of plug-in hybrid electric vehicles (PHEV) in the power system of the substation, this paper studies the substation orderly power consumption optimization control system based on vehicle-to-grid (V2G) technology. This paper first analyzes the impact of PHEV on the grid load, and then proposes an orderly charging and discharging optimization control algorithm, which comprehensively considers multiple objectives such as grid load balance, charging and discharging costs, and user needs. In addition, this paper also discusses the charging and discharging control strategy of V2G charging piles, aiming to achieve efficient energy interaction between the grid and PHEV through intelligent scheduling. By establishing a mathematical model and simulation analysis, this study verifies the effectiveness of the proposed optimization control algorithm and control strategy in reducing the peak load of the grid and improving the operation efficiency of the grid. The research results provide new ideas for the orderly power consumption management of the substation power system, which is of great significance to promoting the development of smart grids.
