基于大规模的风电并网稳定性仿真研究
|
摘要
针对大规模的风电并网稳定性WPGS问题进行研究。利用电力系统分析综合程序PSASP软件,对并入电网后的风电场系统稳定性指标,如节点电压水平和UQ灵敏度进行了仿真研究。采用EPRI-36节点的分布式电网系统,在考虑风电场装机容量、电网电压等级和接入位置等因素条件下,应用PSASP软件对其稳定性进行了仿真,分别从电压水平、灵敏度和PV曲线3个方面进行了研究。仿真结果表明,当这3种因素情况不同时,会产生不同的稳定性问题,所得结论基本与实际相符,从而验证了其仿真的正确性。
This paper studied large-scale wind power grid stability(WPGS). The power system analysis software package(PSASP) was used to make simulation study on stability indicators of the wind power farm system after grid connection, such as node voltage level and UQ sensitivity. PSASP was adopted to simulate the stability of EPRI-36 node distributed grid system, under consideration of installed capacity of the wind power farm, grid voltage level, access location and other factors, and a study was made in the respect of voltage level, sensitivity and PV curve. Simulation results indicate that different stability problems might arise if these three conditions differ from each other. The conclusions basically conform with actual conditions, thus verifying the correctness of the simulation.
