| 针对分布式电源接入配电网带来的电压静态稳定性问题，主要研究含分布式发电的有源配电网电压稳定性。首先提出了根据潮流解来计算整个配电网的电压稳定性指标方法以反映系统各节点的电压稳定性，然后考虑分布式发电作为一个负的负荷直接注入，分别建立了不同类型分布式电源在配电网潮流计算的模型。最后，以分布式电源中典型风电为例，对IEEE 33节点有源配电网进行仿真，分析了不同风机出力、风机接入及有功出力波动对有源配电网系统电压稳定的影响，仿真实验表明分布式电源的接入可以有效提高系统的电压稳定性。 |

| Aiming at the problem of steady state voltage stability caused by distributed generation access to distribution network, the voltage stability of active distribution network including distribution network is mainly investigated in the paper. To reflect system voltage stability of each node, a voltage stability index method is firstly proposed according to the results of power flow calculation for the whole distribution network. Considering distributed generation as a negative load direct injection, different models of distributed generation in power flow calculation are then established. Finally, taking the typical wind power of distributed generation for example, active distribution network of IEEE 33 node is simulated, and different fan efforts, fan access and active output fluctuation influence on the voltage stability of active distribution network system are analyzed in detail. The simulation results show that the distributed network with distributed generation can effectively improve the voltage stability. |
