Automatic optimization algorithm of county power network based on load balancing and feasible set

Aiming at the problem of slow convergence rate of the traditional genetic algorithm and the oneness property of the fitness function. In this paper, we combine the structural property of county power network with genetic algorithm, and propose a new automatic optimization scheme for the county power network operation mode for the purpose of load balancing. By analyzing the structure of a substation, the classification is accomplished according to the main electrical wiring during the coding process, meanwhile, infeasible operation modes are eliminated, and then feasible operation mode is taken as the optimization variable. Finally, the construction scheme of the minimum load balance index of the optimal solution is adopted as the optimal solution. The example shows that the proposed algorithm not only can effectively reduce search spaces, but also with the decrease of the load balance index, the load imbalance is obviously improved, and the network loss is reduced correspondingly.
