Abstract:

To solve the multi-objective optimal power flow (OPF) problem, genetic algorithm (GA) was used to find the Pareto front, and fully reflect the interaction and deviation internal relation of different optimal objective functions. On this basis, Nash Bargaining Game was used to get the global optimal solution. This paper discussed the multi-objective OPF problem with considering the minimum generation cost (or coal consumption) and the minimum system loss simultaneously. This paper firstly verified that the problem could satisfy the Nash Bargaining axiom, secondly obtained the Pareto front by strong Pareto evolution algorithm 2 (SPEA2), which could ensure faster convergence rate and more uniform Pareto front, and then used Nash Bargaining to find the optimal solution and solve the possible contradiction between the different objective function. Case study on IEEE 14-bus system verified the effectiveness of the proposed algorithm.
