基于遗传算法的风电场等值模型的研究
Study on equivalent model of wind farms based on genetic algorithm
摘要
Abstract
Based on the analysis of dynamic mathematic models of a wind turbine system with a squirrel cage induction generator(SCIG), an equivalent modeling method and parameters optimization model of a wind farm are proposed based on an improved genetic algorithm (IGA) by using the operational data ora SCIG wind farm with the detailed models. Regarding the two cases ora wind farm including SCIGs with identical parameters and SCIGs with different parameters, the dynamic and transient performances characteristics under the wind speed disturbance and the three-phase short circuit fault at the exit of wind farm are simulated and analyzed. The results are also compared with those by using the detailed model and the capacity weighted equivalent model of the SCIG wind farm. The results show that the proposed wind farm equivalent model has the same wind farm operation characteristics with the detailed model, and it has better representation of the dynamic and transient performances of the wind farms compared with the weighted equivalent model.关键词
