Research on the method for balancing fluctuant PV power based on hybrid energy storage system
摘要
Abstract
Aiming at the question of balancing the fluctuating photovoltaic grid-connected generation system, a hybrid energy storage-based grid-connected PV power system model is proposed to overcome the fluctuation of grid-injected power caused by the change of illumination intensity and temperature. An ultracapacitor-battery based energy storage control system is employed to smooth the fluctuation of grid-injected power caused by the change of various weather conditions. A new method to track the maximum power point is proposed to modulate the maximum output power of PV system more stably and instantly, and it can also improve the power generation efficiency. Finally, this model is tested by using Matlab/Simulink. The result proves that the hybrid energy storage-based control system can efficiently improve the stability of PV grid-injected power.关键词
