Abstract A hybrid energy system integrates renewable energy sources like wind, solar, micro-hydro and biomass, fossil fuel power generators such as diesel generators, and energy storage. Hybrid energy system is an excellent option for providing electricity for these remote and rural locations where access to grid is not feasible or economical. Reliability and cost-effectiveness are the two most important objectives when designing a hybrid energy system. One challenge is that the existing methods do not consider the time-varying characteristics of the renewable sources and the energy demand over a year, while the mean and variance of a power source of demand are different over the period, and multiple power sources can often times complement one another. A reliability analysis method is developed in this paper to address this challenge, and a numerical example is used to demonstrate the proposed method.
