The aim of this project is to improve the power quality for Distributed Generation (DG) with Active power filter. Power quality is the combination of voltage quality and current quality. Power quality is the set of limits of electrical properties that allows electrical systems to function in their intended manner without significant loss of performance or life. The electrical power quality is most concerned issue. The main problems are stationery and transient distortions in the line voltage such as harmonics, flicker, swells, sags and voltage asymmetries. Distributed Generation (DG) also called as site generation, dispersed generation, embedded generation, decentralized generation, decentralized energy or distributed energy, generates electricity from the many small energy sources. In recent years, micro electric power systems such as photovoltaic generation systems, wind generators and micro gas turbines, etc., have increased with the deregulation and liberalization of the power market. Under such circumstances the environment surrounding the electric power industry has become ever more complicated and provides high-quality power in a stable manner which becomes an important topic. This project deals with the performance of Shunt Active Power Filter (SAPF) for the power quality improvement based on the distributed generation. The real power supply is given by Distributed Generation for the compensation of the voltage related problems. The SAPF has the better performance in the elimination of the harmonics related problems in the distribution side. Here DG is assumed to include Wind power Generation and photovoltaic generation systems. Advantages of this system are constant power supply, constant voltage magnitude, absence of harmonics in supply voltage, un-interrupted power supply. The model system used in this Project work is composed of a Wind Turbine and PV Array. The performance of SAPF is modeled and simulated using MATLAB / SIMULINK.
