Simplified Approach to Evaluate the Reliability of Conventional Generation with Wind Power

Abstract

The purpose of this study is to develop a simplified method to evaluate the reliability of electric power output from a combined conventional and wind electric conversion system (WECS). It provides a simplified reliability model for the WECS output for the use in the reliability evaluation of a hybrid generation system. The method can be extended to include the effect of turbine design parameters and seasonal changes and can be used in reserve capacity planning.Findings and Conclusions: The approach centers around the determination of an effective Forced Outage Rate (FOR) for a WECS. Sensitivity of the FOR value for several key parameters is studied graphically. FOR values for WECS are significantly larger than those for conventional units. This increases loss of load probability value for the combined system. Study will be beneficial at the initial stages of generation planning with WECS.
