In order to improve the power quality problems such as three-phase unbalance and low voltage of low-voltage distribution network caused by load fluctuation, the energy storage application of the distribution network side is promoted according to local conditions, and its application value on the distribution network side is exerted. Considering the operating characteristics of the low-voltage power distribution station area, the energy storage system control strategy applicable to the low-voltage power distribution station area is proposed. Through the phase-separated control of the energy storage system, the effect of improving the power supply characteristics of the distribution network is realized. Finally, a simple distribution network model is taken as an example to verify the simulation. The results show that the control strategy of the energy storage system in the low-voltage distribution area has strong feasibility and effectiveness.
