Power System Distribution Network Planning Based On Hybrid Algorithm

An efficient optimization project for distribution network structure can save investment and the line losses, as well as improve the quality of electric power, which is currently one of the important tasking of the departments of power system. This paper uses investment cost, loss of network, reliability and the environmental effect and so on multi-objective functions to establish mathematics model. Through the fuzzy algorithm and the rough collection method to determine the link between the objective functions, so as to obtain the relative important weight factors attribute to various objectives. And then the pursuit of multi-objective optimization transforms to seek the optimal level of satisfaction of the overall goals. The union improvement PSO algorithm and the Powell optimization algorithm to optimize distribution network planning, and the production of the lots of infeasible solutions have been restored selectivity, to balance the exploitation and local search abilities. The example shows that the method is feasible and effective.
