Abstract
Combining PV power generation and industrial parks and using hybrid energy storage to smooth out fluctuations in PV industrial parks is an effective way to improve the level of PV power consumption, reduce energy consumption and pollution in industrial parks, and lower the cost of power purchase before industrial parks. In this paper, we propose a real-time control strategy to smooth out the fluctuation of PV industrial park by using hybrid energy storage system, which optimally allocates the load fluctuation to energy-based energy storage and power-based energy storage based on variational modal decomposition (VMD), and considers the charging and discharging efficiency and state of charge (SOC) of energy storage to smooth out the fluctuation of PV industrial park. Finally, the effectiveness of the proposed real-time control strategy of hybrid energy storage for PV industrial park fluctuation smoothing is verified by simulation, and the strategy is evaluated economically based on the current spot market in Guangdong.
