【 摘 要 】

In this paper, a method of using battery as the complementary method of energy storage in photovoltaic power generation system is put forward to cut the peak and fill the valley of the output power of photovoltaic power generation, so as to improve the stability of power system and the integrality of power consumption, and thus stabilize the output power quality. The system can achieve the effect of complementary energy. Considering the change of light intensity, the charging and discharging mode of battery is changed by setting voltage threshold based on message driven strategy. The simulation results show that this method can stabilize the voltage, reduce the charge and discharge times of the battery, realize the complementary energy, and prolong the service life of the battery.
