Reliability Evaluation of Decentralized Multi Microgrid Distribution Networks

Abstract

This paper presents an algorithm for reliability evaluation of Microgrids based distribution networks (MDN) with Distributed Generation (DG) based on renewable energy sources (RES). In this approach, DG participates in the network operation coordination as an active agent and not as a decentralized generation under which the utility has no control. Stochastic models are considered for representing generation availability related to wind energy and solar energy. The use of storage is explored as a means of reducing supply intermittency by a specific model for representing the charge state. The influence of microgrids on distribution network reliability is evaluated by considering the probability of success of the islanding operation and the impacts of the storage systems on the power availability.
