Reliability Evaluation and Need Based Storage Assessment for Surety Microgrids

This paper presents a Monte Carlo simulation based approach to estimate the interruption duration distributions at the load buses in a micro grid for the determination of need based storage assessment. Energy limited nature of storage devices is considered for the reliability evaluation. Time variable load and generation profiles have also been incorporated in the method to obtain more practical distributions of interruption durations. The method is demonstrated on a ten bus test system and the results are explained.
