STUDY ON IMMUNE GENETIC ALGORITHM FOR SHIPBOARD POWER SYSTEM SERVICE RESTORATION

To deal with the problems of shipboard power system(SPS) service restoration, a new immune genetic algorithm(GA) is presented in this paper, which introduces new immune operators. The population's diversity is judged and adjusted rapidly and exactly by calculating the locus information entropy. The effects of control parameters, the strategies of extracting a vaccine using the system information and inoculation, the mechanism of immune selection to converting the multi-object problem to single-object calculation for SPS service restoration are all given. The methods of constructing immune operators and parameters selection are also provided. Theoretical analysis and illustrative examples show that the algorithm can improve GA performance, accelerate convergence, avoid premature convergence, increase precision of restoration and the SPS multi-object service restoration is well realized.
