摘要
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.</span></span><span><span><span style="font-family:""> </span></span></span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;">The Net Present Cost (NPC), </span></span></span><span style="font-family:Verdana;"><span style="font-family:Verdana;"><span style="font-family:Verdana;">and</span></span></span><span><span><span style="font-family:""><span style="font-family:Verdana;"> the Levelized Cost of Electricity (LCOE), were the two crucial economic factors considered.
