Feasibility Analysis of an Islanded Microgrid in Tohatchi, New Mexico Using HOMER Pro
Abstract: Microgrids are becoming more popular in areas where there is still no connectivity to the main grid largely due to their remote geographical location. This paper focuses on the feasibility analysis, using the HOMER Pro simulation program, of an islanded micro-grid for the Navajo community in Tohatchi, New Mexico using different energy mixes of a Photovoltaics (PV) system, a Wind Energy system, a Battery Energy Storage System (BESS) and a Diesel Generator. The Net Present Cost (NPC), and the Levelized Cost of Electricity (LCOE), were the two crucial economic factors considered. Through the analysis, the system with the PV, wind turbines, battery, and a diesel generator was found to have the lowest LCOE and NPC. There was a reduction of 75% in the costs of the combined system as compared to the diesel-only base case. Also, this combined system provided the minimum emission levels. The analysis suggests that the integration of renewable energy using microgrids to help the access of energy for rural areas was possible. The analysis could very well be extended to any other community by considering the wind and solar resources present at that location.
