Power quality improvement in a grid integrated solar PV system

At present, Power Quality is one of the key elements, which influences the economy of a nation. Due to rising of population utility supplies excess power to meet the increasing demand of the consumers. To maintain the pollution and the global warming within the particular level alternate sources of energy have used which devolops the pollution less environment. To overcome those issues non-conventional energy come into picture. The whole performance of the electrical utility can be improved by the usage of non-conventional energy resources. There are different forms of Renewable Energy Resource (RES) are available. Among them solar energy is mostly used because it is abundantly available in nature. In addition it has lot of advantages such as no air pollution, no fuel cost, noiseless and low maintenance. Integrating solar power to the grid has adverse effect on the power quality in the grid. In a few PV based framework, the inverter is a key segment which is responsible for the control of power stream between the dc source, and loads or lattice. This paper describes the difficulties and issues in the area of power quality the due to the integration of solar power in to grid are to be analysed. The Shunt Active Power Filter (SAPF) with PI controller is to be designed to enhance power quality in the grid integrated solar system.
