Improving the quality of energy using an active power filter with zero direct power command control related to a photovoltaic system connected to a network

Introduction. This article’s subject is a dual function energy system that improves the quality of electric with help an active power filter and uses new technique command named ZDPC (Zero Direct Power Command) on one hand, other hand it injects photovoltaic (PV) renewable to electrical networks in presence non-linear charges. The novelty work consists subtraction disturbances resulting from charges provided by based method. Methods. strategy combines classic PI controller for DC bus voltage regulation smart method maximum point tracking (MPPT) fuzzy logic. Purpose. elimination undesirable harmonics source currents makes current almost sinusoidal harmonic distortion rate close 1 %. injection PV into grid panel series chopper through two-state inverter. Results. simulated using MATLAB/Simulink software. results prove robustness feasibility control which simultaneously guarantees compensation currents, correction factor solar grid.
