Abstract

A microgrid is an emerging frontier in meeting the challenges in providing reliable power supply to a small community. Microgrid operation is one of the important topics on microgrid. The goal of microgrid operation is to maintain power balance. In an islanded operation mode of a microgrid, when power imbalance occurs by supply shortage, load shedding is generally used. For an efficient and fair load shedding, some game theoretic approaches have been proposed. The load-shedding schemes consider that a power consumer uses a continuous range of values to present its power demand. However, in reality, some consumers use integer and discrete values and it limits power utilization. In this paper, we define a load-shedding problem with consideration of the discrete characteristic of power demands. To solve the load-shedding problem, we employ a game theoretic approach. In order to show the functionality and performance of our load-shedding scheme, we implement a microgrid operation system by using our scheme.
