Research Of AFSA In The Application Of Distribution Network Planning

The dissertation systematically discusses the theory of artificial fish swarm algorithm (AFSA).The AFSA has some good abilities, which can overcome the local extremum, and get the general extremum. We can find satisfying domain of answer in an easy way, but we can't find the accurate optimal answer by using it. Considering its big objection in astringency and computing complicacy, this paper introduces some schemes, which we can improve on the AFSA by using them.Focuses on the improvement program of AFSA which adapt to the optimal planning on distribution network structure and distribution network switch. And the dissertation also introduces the realization process of modified AFSA application in distribution network structure optimal planning and switching optimization, designs program using Visual C# development platform and calculates the examples using AFSA and modified AFSA, the results indicate that the modified AFSA is superior than AFSA in calculate efficiency and global convergence.The researches indicate that the modified AFSA is efficiency and feasible application in distribution network optimal planning.
