Novel analytical approach of reliability evaluation for a wind-diesel hybrid power system with a battery bank for power supply in the remote areas is discussed. This model computes a power output of wind-turbine generators (WTGs) for each discrete wind-speed frame, which is created by splitting the Weibull wind-speed distribution curve. The reliability analysis of the overall system is conducted by combining power outputs of the wind and diesel generation units with battery throughout all wind speed frames. Wind-diesel hybrid power systems considerably reduce the need for fuel storage, fuel consumption cost, and greenhouse gas emission as opposed to their conventional diesel-only counterpart. A short-term system reliability index can then be obtained by associating this model with the load-duration curves within each discrete time frame. This model can assist the electric utility system planning engineers and management to evaluate, upgrade, size, and optimize their hybrid power systems.
