Optimal harmonic power flow

A new Optimal Harmonic Power Flow (OHPF) method is proposed in this paper. This new OHPF is designed to minimize the MW losses and the total harmonic voltage distortion while satisfying the power flow equations, harmonic power flow equations, security constraints and harmonic standard, etc. A two-level algorithm is used to solve the problem: the master level determines the settings of compensators and taps; the slave level includes subproblems which involve cases of fundamental and harmonic frequencies separately. The test results for two power systems show the applicability of the proposed method.
