Fuzzy control based APF with DG integration for power quality improvement in disribution system

摘要

Power quality is the major problem in the electrical distribution network, out of various power quality problems; harmonics problem is major in distribution network. Various FACTS controllers are proposed for mitigation of power quality problem in the distribution network for harmonic compensation Active power filter is proposed. Another major problem in the power system network is increasing load demand day by day to meet the increasing in load demands renewable energy sources (RES's) are inter connected to the distribution network. For integrating any type of renewable energy sources (RES's) we need a voltage source converter (VSC) one for power quality improvement, another for integration of DG. This work proposes a fuzzy controlled SRF theory based APF with DG integration In the proposed system the fuzzy control circuit will perform the function of harmonic elimination, so that the need for an APF (Active Power Filter). Implementation of a fuzzy logic controller by using voltage as feedback for significantly improving the dynamic performance of proposed APF module with good stability factor is to be achieved. The system of DG integration with APF controlled by Fuzzy is modeled using MATLABSimulink. The operating conditions are demonstrated to improve the power quality is simulated using MATLAB/SIMULINK.
