Abstract

Considering the problem of voltage sag when the AC line of the distribution network has a short-circuit fault, an energy storage system control strategy to improve transient voltage stability of distribution network is proposed in this paper. Firstly, the influence on the voltage of the distribution network under the short-circuit fault for the distribution network is analyzed, and the ability of energy storage to participate in voltage regulation of the grid is analyzed. Secondly, considering the actual operation mode of the energy storage system, an energy storage reactive power control strategy including plant level and local control is proposed. The plant-level control uses the constant voltage control method, and the local level adopts the reactive power-voltage coordinated control method. Reactive power output is adjusted by bus voltage changes to improve transient voltage stability. Finally, the simulation analysis of the CEPRI36V7 power grid model in the Power System Analysis Software Package (PSASP) is carried out to verify the effectiveness of the proposed energy storage control strategy.

提高配电网暂态电压稳定性的储能控制策略

针对配电网交流线路发生短路故障时的电压暂降问题，提出了一种提高配电网暂态电压稳定性的储能系统控制策略。首先分析了配电网短路故障对配电网电压的影响，并分析了储能参与电网调压的能力。其次，结合储能系统的实际运行模式，提出了电站级和局部控制相结合的储能无功控制策略。厂级控制采用恒压控制方法，局级控制采用无功-电压协调控制方法。通过母线电压变化调节无功输出，提高暂态电压稳定性。最后，在电力系统分析软件包(PSASP)中对CEPRI36V7电网模型进行了仿真分析，验证了所提储能控制策略的有效性。
