Abstract :
Renewable energy is increasingly being treated as a promising solution to the global warming and other environment issues. Due to the intermittent nature of these energy resources, energy storage is required to provide certain wind generation capacity. An analytical procedure is presented in this paper to analyze the impacts of energy storage on reliability of power systems with wind turbine generators (WTGs). An operating strategy of energy storage is simulated. The Expected Energy Not Supplied (EENS) index is used to investigate the impacts of the rated capacity of energy storage and initial stored energy, and the number of WTGs on system reliability. Expected Energy Not Used (EENU) index is defined to present energy wasted from a wind farm.
