Optimum Power Control And Quality Management In Dg- Integrated System

Abstract

Our main focus of this paper is to control the active power supplied by distributed generation (DG) system while
reducing and compensating harmonics & reactive currents caused by the nonlinear loads using shunt active power filter
(APF). The APF control is basically based on load currents which sense the reference current estimate in a-b-c reference
frame. The active power transfer is the function of power angle and the reactive power transfer is the function of voltage
magnitude difference between the inverter voltages and the grid voltages. The widespread simulation for the study is carry
out with the help of MATLAB / Simulink to show the usefulness of algorithm. Various types of simulation results are
presented with integrated modes of operation for distributed generation system interfaced with grid.
