Abstract

This paper proposes a probabilistic technique to evaluate the success of islanded microgrids taking into consideration the impacts of voltage and reactive power constraints and the special features and operational characteristics of both dispatchable and wind distributed generators in islanded microgrids. New adequacy and reliability indices are proposed to account for the effect of voltage and reactive power constraints. To facilitate these studies, the proposed technique employs a microgrid model that reflects the special characteristics of microgrid operation. Simulation studies have been carried out to validate the proposed technique. The simulation results show that voltage and reactive power constraints have considerable effects on the microgrids successful operation.
