ABSTRACT

The membrane computing method is proposed to solve the power system dynamic economic dispatch problem in this paper. The unit generation power during 24 hours is taken as the membrane object. Based on the cell type nested membrane structure, a set of evolution rules including crossover, mutation, correction, reserve, transition, abstraction and target indication are established to optimize the dynamic economic dispatch of power system. The IEEE 39-bus system is used as the test example. The simulation results show that the optimization problem of dynamic economic dispatch can be solved effectively by the proposed membrane computing method, which can obtain a better optimal solution and has a more stable results comparing with the genetic algorithm and particle swarm algorithm. This proposed membrane computing method has a good application prospect in optimization.
