Determination of locations and sizes for active power line conditioners to reduce harmonics in power systems

The APLC (Active Power Line Conditioner) is a type of active power filter that compensates the voltage waveform distortion caused by harmonics in power systems. This paper presents a new approach based on an optimization theory to investigate the determination of locations and sizes of APLCs. The objective is to minimize the new APLC injection currents and the voltage distortion while satisfying the harmonic standard. The test result for an 18-bus distribution system shows the applicability of the proposed method.
