Abstract

为改善因负荷波动带来的低压配电网三相不平衡和低电压等电能质量问题，因地制宜推进配电侧储能应用，充分发挥其在配电网侧的应用价值。考虑低压配电台区运行特性，提出适于低压配电台区的储能系统应用控制策略，通过对储能系统的功率控制，实现其改善配电网供电质量的效果。最后，以简单配电网模型为例进行仿真验证，结果表明，所提低压配电台区储能系统控制策略具有可行性和有效性。 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.
