Small islands without grid connection as natural mini-grids are perfect examples for the shift of conventional power generation systems towards renewable energies.Within this work the energy supply system of the Caribbean island Petite Martinique (150 kW peak load, 820 MWh per year) is technological and economic optimized using diesel gensets, photovoltaic, wind power and energy storage systems. The final results show, that a system with a renewable share of almost 85 % is ideal. This system consists of 175 kW PV, one wind turbine (225 kW) and 200 kW / 400 kWh storage capacity saving each year 274,000 liter diesel.
