基于粗糙集理论与CLSDE算法的环境经济调度优化模型
An Environmental Economic Dispatch Optimization Model Based on Rough Set Theory and Chaotic Local Search Strategy Differential Evolution Algorithm
摘要
Abstract
In allusion to environmental economic dispatching optimization, a multi-objective optimization method that constructs evaluation function by rough set theory is proposed, and a solving algorithm based on chaotic local search strategy differential evolution (CLSDE) algorithm for the proposed model is put forward. The constraint degrees of economic dispatching and environmental dispatching function are determined by rough set theory to decide the weight values of objective functions in the proposed optimization model. The CLSDE algorithm is used to solve the multi-objective optimization model of environmental economic dispatching (EED) and this algorithm only encodes the variables in the objective functions; the variables in constraint condition functions are produced at random. After the evolution of each generation is completed, the chaotic local searching is performed to optimal individual, thus both the weak local searching ability of differential evolution algorithm and the difficulty of choosing penalty parameters in the penalty function method can be overcome. The standard IEEE 30-bus system is used to test the proposed method and simulation results show that the CLSDE algorithm is feasible and effective for the solution of environmental economic dispatching, using the proposed method the fuel cost can be reduced while the pollution gas emission is not increased, herefore the environmental economic generation dispatchingcan give consideration to both economic benefit and environmental benefit of generation dispatching.关键词
