Abstract

In recent years, interests on the microgrid have been growing because it is a small-scale power system including clean energy sources, such as solar power, wind power, and fuel cells, as its major energy sources. To meet the rating frequency, 50 or 60 Hz, is an important requirement for microgrid operation. The frequency is closely related to a balance between power supply and power demand. Especially, load shedding, which is an intentional load reduction, is used in order to maintain the frequency in the case of supply shortage in the islanded operation mode. For this reason, the fairness for load shedding is an important topic for the load-shedding problem. Recently, the load-shedding scheme using the bankruptcy rule has been proposed as a reasonable method. In this paper, the load-shedding schemes using four well-known bankruptcy rules are compared and discussed in the viewpoint of fairness. For this, the fairness index is customized to evaluate fairness of load-shedding schemes for islanded microgrid operation in a multiagent system.
