      Abstract: In order to solve the contradiction between the maximum consumption of new energy and the

reserved power flow margin of operation section,a day-ahead coordination optimization method for complex

cascaded power grid based on key section identification was proposed to achieve the orderly coordination among the three objectives of improving the efficiency of power grid operation,promoting the consumption of new energy and ensuring the safe and stable power grid operation. An evaluation index of high-risk over-load operation section in cascaded power grid was proposed by considering two main uncertainties of new energy and power load to identify the key sections which restrict the consumption of new energy. On the basis of insisting on global coordination and optimization,the power flow regulation resources for operation sections of each dispatch mechanism are reasonably reserved according to the distribution of key sections. The optimization model takes the maximization of new energy consumption and power system operation benefit as the optimization goal and considers the constraints including the sufficient adjustment capacity for key sections. The results show that this method can effectively realize the orderly connection of the goals of safety,economy and cleanliness,and effectively upgrade the clean energy absorption capacity of the connected power grid system by improving the power flow safety of the operating section.
