Abstract: Considering the current challenges posed by energy structural transformation on remote islands, the technical and economic assessment of a hybrid renewable power system were performed considering the Huraa Island of Maldives as a case study. This work models and discusses possible hybrid power system configuration modes based on varying combinations of diesel power, solar photovoltaic (PV) power, wind power, and battery storage. For each mode, the effects of the installed capacity on renewable penetration (RP) and levelized cost of electricity (LCOE) were analyzed. Furthermore, the configuration modes were compared, and optimal operation schemes were developed by considering RP, LCOE, and CO2 emissions. The results suggest that the use of a high-rated PV power is optimal owing to its high RP and low LCOE. However, when wind power is available, a wind power rating of 1000 kW is an optimal solution, followed by a 500-kW rating; when battery storage is used, a battery capacity of 4000 kWh is ideal. Moreover, it is unnecessary to combine battery storage with these power schemes when an RP <53% is acceptable. The recommended maximum available RP is approximately 96% when using an 1800 kW PV, 1000 kW wind, and 4000 kWh battery storage system.
