Modelling of an expandable, reconfigurable, renewable DC microgrid for off-grid communities

摘要

This paper proposes a DC microgrid system, comprising multiple locally available renewable energy sources in an off-grid rural community, based on a commissioned field study carried out in a rural, off grid village in Nepal, which has solar and wind resource available. Using estimated solar data for the site's location, wind data measured locally, household and population data collected over the course of several months and typical measured domestic demand profiles, DC microgrid system models have been constructed using HOMER and Simulink software to represent the DC system proposed.
