Abstract—Isolated areas are usually located a distance away from the main power grids where supplies of electricity rely on diesel generators. Although the initial investment cost of diesel generators is usually low, the fuel cost can be very high over a period of time. Consequently, renewable energy sources such as photovoltaic systems (PV) and micro-hydro generators are used in conjunction with diesel generators to reduce fuel cost. However, poor management and coordination of the energy sources may not solve the issue of high fuel consumption. In order to address this effectively, an innovative energy storage system is developed to coordinate with various energy sources to reduce the fuel consumption to a minimum. The energy storage system is controlled by a fuzzy controller which is able to extend the shut-down period of diesel generators and hence minimize fuel consumption. The performance of the energy storage system, as verified in MATLAB/Simulink, indicates that fuel consumption is reduced by 8 %.
