| Abstract | Electricity access in Thailand achieved almost 100% household currently, remaining few remote or isolated areas due to the difficulty of grid connection as well as the high distribution system cost. In these areas, electricity distribution is made up of a microgrid system typically from fossil fuel resources such as diesel generator which has high fuel cost and cause air and noise pollution. To mitigate these issues, using renewable energy available in these areas to generate electricity can help to reduce LCOE and the pollution generated by diesel generators. In addition, according to Thailand’s Power Development Plan (PDP) and Alternative Energy Development Plan (AEDP), Thailand focuses on the promotion of microgrid systems in remote area in order to maximize resources usage in each area and aims to increase the share of final energy consumption to 30% of total energy consumption in 2036. Tao Island is one of the isolated areas located in Suratthani province which electricity is supplied by diesel generator. Therefore, the purpose of this study is to design the optimal renewable energy and energy storage system for the island with respect the technical and economic perspective by using the data collection and HOMER Pro to simulate among the various energy options. The potential as well as the constraints to apply renewable energy technologies at the island has been investigated to design the least cost energy system without energy shortage. The simulation result among five different case scenarios for electricity supply at the island for 17-years’ timeframe with average annual demand growth at 3.3%, the hybrid renewable energy along with battery storage system can reduce the electricity production cost from diesel generator. The optimal option consists of PV/WT/Biomass and lithium-ion battery storage at 27.4% renewable energy fraction operate together with diesel generator provides the lowest NPC at $90.86M, can reduce LCOE from $0.266/kWh in the diesel generator-based case to $0.213/kWh or 20% reduction. Moreover, the emission reduction from the optimal system can reduce CO2 emission 144,228.03 tons compared to the based case (DG only) at the end of project lifetime. |
