Abstract

This paper describes enhanced technique of power quality at utility end in a network framework associated with renewable source of energy for power generation. With advancement of new functionalities sunlight based vitality based Photovoltaic cells are forthcoming energy source with higher efficiency. With the increase in load demand, the Renewable Energy Sources (RES) are increasingly connected in the distribution systems which utilizes power electronic Converters/Inverters. The Photo Voltaic (PV) Panel is modeled based on associated equations. The utilization of non-linear loads in the power system will prompt the era of current sounds which thusly break down the power quality. The Problems like current unbalance current harmonics and also of injecting the energy generated by renewable energy source. The inverter is controlled on the basis of hysteresis control and thus it can be utilized as a power converter injecting power generated from RES to the grid. When the power generated from RES is more than the total load power demand, the grid-interfacing inverter with the proposed control approach not only fulfills the total load active and reactive power demand but also delivers the excess generated sinusoidal active power to the grid at unity power factor. This work is completed utilizing MATLAB/Simulink software. Keywords: active power filters, distributed generation, grid interconnection, grid interfacing inverter, photo voltaic cell
