摘要
以风电场实测出力数据作为等值建模的分群依据,建立风电场的等值模型,将等值模型与风场详细模型进行对比验证所提出分群方法的有效性,并将风场等值模型并入四机两区域系统,经过概率计算得到系统的分布特性。最终结果表明,风电场并入传统电网使得原系统的小扰动稳定概率降低。
The equivalent model of wind farm was established by taking the measured output data of wind farms as the basis of the clustering process.The effectiveness of the proposed clustering method was verified by comparing the aforementioned equivalence model with the detailed wind power model.The wind farm equivalent model was merged into the fourmachine two-regional system,thus the distribution characteristics of the system could be obtained by probability analysis calculation.The ultimate results showed that the access of wind farms to the traditional power grid could reduce the probability of small disturbance stability of the original system.
