Interconnected Microgrid Systems for Remote Areas

Chapter

Abstract

To reduce the frequency and necessity of load-shedding in a remote area microgrid during autonomous operation, islanded neighboring microgrids can be interconnected temporarily to support each other, if a proper overload management technique is in place and an extra generation capacity is available in the distributed energy resources in the neighboring microgrids. Otherwise, due to the unavailability of a utility feeder in remote areas, load-shedding is the only alternative to managing an overloaded microgrid. This way, the total demand of the system of coupled microgrids will be shared by all the distributed energy resources within these microgrids. To this end, a carefully designed overload management technique, protection systems, and communication infrastructure are required at the network and microgrid levels. In this chapter, first, the conditions and constraints based on which two neighboring microgrids are coupled are described. This is extended to develop an algorithm which identifies suitable microgrids to support the overloaded microgrid(s) when several neighboring microgrids exist in the distribution network.
