Power Quality Improvement Based on Five-Level Shunt APF Using Sliding Mode Control Scheme Connected to a Photovoltaic
This paper presents a compensating system for the harmonic currents, the reactive power in three-phase distribution system by using a five-level inverter based shunt active power filter (SAPF) connected by a photovoltaic system. A controller based on the p-q theory is introduced for the SAPF. The distribution network which supplies non-linear load and employing five-level inverter based SAPF connected by a photovoltaic system is simulated by MATLAB/SIMULINK software. The performance of SAPF is analyzed by using the proposed control technique on the total harmonic distortion of source current, power factor and reactive power. Besides, it is illustrated by extensive simulation results, the effectiveness of five-level SAPF connected by a photovoltaic system.
