OPTIMAL HARMONIC POWER-FLOW

A new Optimal Harmonic Power Flow (OHPF) method is proposed in this pa per. 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 sta ndard, etc. A two-level algorithm is used to solve the problem: the ma ster level determines the settings of compensators and taps; the slave level includes subproblems which involve cases of fundamental and har monic frequencies separately. The test results for two power systems s how the applicability of the proposed method.
