    Abstract

    This paper proposes a DC microgrid system based on multiple locally available renewable energy sources in an off-grid rural community, based on a field study carried out in a rural, off-grid village in Nepal. The site has been assessed as suitable for solar and wind power. Using estimated solar data for the site’s location, wind data measured locally, household and population data and typical measured domestic demand profiles, a DC microgrid system model has been constructed. Power flow is controlled using modified DC droop control on each individual energy source to enable optimal power sharing with minimum power dissipation across distribution lines.
