Method for configuring intelligent charging system for electric vehicles in expressway service areas

Abstract

The invention discloses a method for configuring an intelligent charging system for electric vehicles in expressway service areas, comprising: constructing a time series model of electric vehicle charging load reflecting the characteristics of working days, holidays, and different seasons based on historical data statistics; assessing the maximum installed capacity and time series generation capability of distributed photovoltaics in service areas through spatial identification and meteorological data analysis; setting three types of configuration scenarios based on known charging demand and photovoltaic resources; conducting dynamic simulation of various configuration schemes under multiple preset scenarios to obtain key performance indicators of system operation; quantitatively evaluating the simulated system operation performance from multiple dimensions such as reliability, economy, and energy efficiency; and applying multi-objective decision-making methods to screen out the overall optimal system configuration scheme based on comprehensive evaluation results. The invention realizes prediction of charging demand, optimized utilization of renewable energy, dynamic regulation of grid load, and closed-loop optimization of charging scheduling.
