The relationship between centralized photovoltaics and energy storage

Frontiers | Multi-objective optimization strategy for the distribution

The energy storage system (ESS) can effectively suppress the power output fluctuation of the PV system and reduce the PV curtailment rate through charging/discharging states. In order to improve the operation capability of the distribution network and PV consumption rate, an optimal multi-objective strategy is proposed based on PV power prediction.
