| Abstract:It shows a huge potential for flexible load access area grid to participate in power scheduling so as to improve the power system regulation capability, but it also brings additional complexity in system power scheduling control. In order to solve this problem, it is urgent to build an objective, fair, accurate and effective comprehensive evaluation system, which can guide flexible loads to participate in power scheduling, Firstly, aiming at the characteristics of regional flexible load participating in power dispatching, a comprehensive evaluation index system with flexible load as control object and optimal allocation of energy as objective is constructed. Secondly, combined weights that objectively evaluated are obtained by adjusting subjective weights which are determined by analytic hierarchy process using entropy weight. Then, the grey relational analysis method is used to evaluate the power scheduling participation degree of different kinds of loads, and the priority of each load under different scheduling modes is obtained. Finally, it is verified in a regional energy control center demonstration project, the evaluation system can guide the various types of load in the region to participate in power scheduling, reduce the peak power consumption and maintain reliable operation of the power system.
