Extended Microgrid Using (DER) Distributed Energy Resources

Abstract

The electric power industry is in the midst of a critical period in its evolution. The re-regulation of the industry has resulted in the creation of self-locating merchant generation and wholesale electric power markets that are using the transmission system in ways for which it was not designed. This had resulted in a system operation closer to its edge. The retail customers have increasingly sophisticated energy service requirements that require much higher power quality than in the past. On way to approach these issues is to focus on robustness at the networked transmission and generation system while providing reliability locally. The distribution system should focus on providing the customer with the required level of power quality. Distributed energy resource (DER) is a way to enhance the distribution system's level of power quality.
