A Practical Method for Optimized Reactive Power Sharing Among Passive Filters

Abstract

This paper presents a practical method for reactive power sharing among harmonics filters. The proposed method minimizes the total harmonic distortion of the current. The current is measured at the incoming bus to which harmonics filters are connected. The total harmonics distortion and individual harmonics of the voltage at the bus to which the harmonic filters are connected and the individual harmonics of the current measured at the mentioned measurement point are used as constraints of optimization. The Optimization Toolbox of MATLAB software is used in this paper. The simulation results show the efficiency and robustness of the proposed method.
