Dynamic Capacity Expansion Solution for EV Charging Stations: Leveraging Energy Storage Systems
Challenge Overview
Electric vehicle (EV) charging demands high power, significantly impacting the grid despite relatively low total energy consumption. As EV adoption grows and charging power escalates, stations seek to expand charging pile numbers and capacities, necessitating distribution capacity upgrades. Traditional approaches involve adding distribution transformers, which incur high costs and exhibit low utilization rates. The optimal solution lies in deploying energy storage systems for dynamic capacity expansion.
