A multi-objective optimization method for precise load shedding control of power system based on POA-GWO-CSO algorithm
In order to solve a series of security problems such as system frequency and voltage offset caused by power shortage in power system,this paper proposes a multi-objective optimization method for precise load shedding control based on POA-GWO-CSO algorithm.Firstly,a multi-objective optimization model of precise load shedding control based on load classification is proposed from the aspects of safety and economy of power system,considering the constraints of stable operation of power system and output characteristics of distributed generation.In order to enhance the coordination relationship between global and local search in the traditional pelican optimization algorithm(POA),and to overcome the problems of premature convergence,insufficient optimization range and low accuracy of the optimization algorithm in dealing with complex problems.In this paper,the nonlinear inertia weight factor,the wolf group leader strategy in the grey wolf optimization algorithm(GWO)and the crisscross optimization(CSO)are introduced to update the position of the new individual of the pelican.Finally,based on the empirical analysis of the modified IEEE33 node,the improved POA-GWO-CSO algorithm proposed in this paper is used to solve the emergency load shedding model,and the system coordinated control of economy and stability is realized.
