Hybrid renewable energy system integration in the micro-grid: Indian context

Electricity production from renewable energy sources (RESs) can be attractive, efficient and pollution free idea for remote locations in India. For remote locations domestic load, RESs that can be solar, wind, small hydro and biomass considered for a trustworthy alternative to reducing the dependency on fossil fuels. Due to the variance in the electric output of RESs, these can't be operated smoothly without integration in the micro-grid. So, integration of RESs is necessary for system operators. Therefore, hybrid renewable energy system (HRES) can be counted to cope up with irregular electric supply and transmission lines problems in remote areas. Moreover, HRES integration into the micro-grid can reduce dependency on main-grid supply and also improve reliability of electricity. However, HRES can create problems when their execution is attempted to be realistic. So, hilly remote areas HRES integration into the micro-grid is a great challenge to Power Engineers. Therefore, a comprehensive analysis on HRES and micro-grid technical as well as commercial issues and challenges is presented in this article.
