With the continuous improvement of the intermittent new energy grid connection, the influence of solar energy and wind power generation on the power grid operation is becoming more and more random. In order to measure the correlation of wind power, the Copula theory is introduced into the scheduling strategy, and the correlation of Kendall rank correlation coefficient is adopted. At the same time, in order to coordinate the economy and reliability of the system, it is suggested that the fuzzy chance constraint is introduced to define the level of scenery complementary and credible, and reduce the blindness of the allocation of wind power and the decision of the reserve capacity. Finally, the robust optimization scheduling model is simplified into two sub programming problems. The optimal dual interior point method is used to solve the problem. The results show that the model is feasible, robust and economical.
