摘要：
As the correlation of multiple wind power outputs is of great significance for the economic dispatch analysis of wind farm power systems, the mix vine time-varying Copula (MVTV Copula) is proposed to construct the random scenarios of multiple wind power outputs.The economic dispatch model is built with the objective of minimizing unit fuel cost and dispatch cost. An IEEE-30 node system is referenced and the measured outputs of three neighboring wind farms in China are used to validate the proposed method. The simulation results show that the cost of the economic dispatch that ignores the correlation of wind power output is only 43.6% of the actual scheduling cost, while that of the model based on the MTVT Copula method is much closer to the actual scheduling cost, being 82% of the actual cost. It is proved that theoutput model of multiple wind farms is more consistent with the actual situation, which can well describe the relevant characteristics of multiple windfarm outputs, and the economic dispatch based on this method can yield ideal dispatch results.
