Renewable energy micro-grid power system for isolated communities

Technological advancement in the renewable energy industry is increasing the feasibility of incorporating renewable energy sources into the power systems of isolated communities. Previous studies have demonstrated how renewable energy resources can be incorporated into remote area power systems, in order to reduce operating costs and harmful emissions. The variable nature of renewable resources, however, is still an obstacle that needs be overcome in order to provide a robust power system using solely renewable energy technology. Research on optimising power systems reliability, has led to multiple methods for improving the design of robust renewable energy systems. This paper proposes a stand-alone power system that uses wind and solar energy, as well as a hydrogen fuel cell back up supply. The energy sources are combined with specific control techniques in order to totally eliminate the need for a diesel generator. A requirement of this proposal is that all major elements be commercially available.
