A WAVELET TRANSFORM AND DATA MINING TECHNIQUE BASED PROTECTION TECHNIQUE FOR MICROGRID

Abstract

With the emphasis on reducing carbon footprint and promoting the utilization of non renewable resources of energy in production of electricity, the micro grids have emerged as popular arrangement. Micro grids have empowered the users with flexibility in generating & controling electricity as per their requirements and have reduced their dependence on utility grid. Also they can now transfer surplus electrical energy to utility grid and can earn monetary gains. Photovoltaic systems have emerged as indispensable alternative over other distributed energy resources that can be inetrated in microgrids due to their simple design, easy to install and easy to maintain features. However the deep penetration of microgrid systems is posing threat to reliable & optimal operation of main utility grids.
