Isolated microgrid design problem considering resiliency indices

Abstract

In the last decade, the microgrid concept has been widely regarded as important issues in the literature as well as in the practice. Reducing greenhouse gases, reduction of transmission losses, enhancement in the passive defence strategies and increscent in the local reliability are the main interests in the using of microgrid systems. On the other hand, isolated microgrid systems have been broadly implemented in the remote sites where an interconnection with the main grid is not feasible due to either technical or economic constraints. In this paper, we investigate isolated microgrid design problem considering natural disaster. Indeed, the performance of Distributed Generation (DG) systems are evaluated in the disaster events according to the resiliency indices and finally the model is proposed to minimize the microgrid initial investment costs considering resiliency and reliability constraints.
