Abstract

Now a days with the large growth of industrialization the demand for power is increasing. The environmental pollution, global heat etc, have made us to think for alternative source of energy called renewable energy source. These include solar, wind, hydro-power which is replacing the fossil fuels like thermal, nuclear etc which have very harmful effects with the release of CO2, SO2 and other harmful wastes, toxic gases which effect the environment very badly. These renewable energy source, solar is the powerful energy we receive from sun with free of cost without making any harm for environment. Along with this, wind energy also contributes for solving the power problem. These two sources are integrated with the grid. The Power quality plays a major role, where intelligent converters play a major role in the integration of wind and solar energy with the grid. Along with converters application of Flexible Ac Transmission Systems (FACTS) into the grid also helps in reducing power quality issues. In this paper we have discussed some of the hybrid techniques to be interfaced with the grid so that the power quality issues can be reduced.
