Electric Vehicles as a Key Component of Smart Grids

Electric vehicles serve as a critical element in smart grids, effectively addressing energy shortages and environmental pollution. Wireless charging technology enhances grid-vehicle interaction, enabling better peak shaving, valley filling, and renewable energy integration. Based on China's EV policy framework and wireless charging characteristics, this study employs Monte Carlo simulation to sample private EV travel distances. By analyzing battery charging patterns and driving habits, we derive initial state of charge, charging power, and charging start time to develop an accurate mathematical model for predicting wireless charging load. The model forecasts private EV charging loads for 2015 and 2020.
