Abstract
In view of the model of single Copula function containing larger distortion defects in describing wind power correlation, a strategy of comprehensive Copula function model is put forward to depict the correlation structure, and EM method is used to estimate the value of the related parameters in the model.Two adjacent wind farms in a certain area of actual historical output data as the foundation, by comparing different combination functions of goodness of fit check, we select the most optimal comprehensive Copula function, and apply it in the probabilistic power flow calcula-tion of the system.The two probability density curve of the branch active power and the node voltage is made.By comparing with single Copula function of income curve, the effectiveness and feasibility are verified in modeling of wind farm output.关键词
