The term "microgrid" refers to the concept of a small number of DERs connected to a single power subsystem. DERs include both renewable and /or conventional resources [3]. The electric grid is no longer a one-way system from the 20th-century [4]. A constellation of distributed energy technologies is paving the way for MGs [5], [6], [7].
