A FUZZY OPTIMIZATION ALGORITHM OF MULTIOBJECTIVE OPTIMAL POWER FLOW

Fuzzy set theory and nonlinear primal-dual path following interior point method is used for solving multiobjective optimal power flow problem with soft constraints. By selecting suitable acceleration factor the convergence is improved. Furthermore, the results of multiobjective fuzzy optimization are compared with the ones of nonlinear optimal flow problem with single object function. The results of several test systems show that this proposed algorithm has stable convergence, good optimization accuracy, flexibility, strong ability to deal with variable and function inequality constrains, and is suitable for solving multiobjective optimization problem of large scale power system.
