Optimization strategy for PV-powered EV charging stations relying on V2G
Scientists in China have created an optimization technique for an electric vehicle charging station that uses PV, battery storage, and a vehicle-to-grid operation. Considering the uncertainty of PV generation and the randomness of EV load, the system uses two-level optimization, day-ahead and intra-day.
Stochastic optimization for PV-powered EV charging stations
Scientists have developed a new optimization approach that combines both day-ahead optimization and real-time optimization to improve operations of PV-driven EV charging stations. The framework is based on the autoregressive moving average and the Latin hypercube sampling models.
