Research on Medium Voltage Distribution Network Planning Method Based on Improved Genetic Algorithm

In this paper, an improved multi population genetic algorithm is proposed to solve the multi-objective optimization problem with multiple groups (father, son, elite group). The parent and subpopulation are introduced into adaptive operators, and the parent and sub populations carry out information exchange at a certain frequency, and the best individuals are saved by the best individuals. The analytic hierarchy process (AHP) is used to make the fuzzy weight operator of the planners more accurate: the multi power sources are included in the distribution network planning, which is closer to the real power grid planning of large cities; the improved algorithm and scheme proposed above are applied to the medium voltage distribution network planning to realize the global optimization.
