Review of microgrid architectures - a system of systems perspective

To better cope with the challenges posed by the world today, the transition of systems engineering principles to complex, large scale, integrated and evolutionary system of systems (SoSs) has occurred. On the other hand, distributed generation has made its mark in the power distribution system, as a consequence of economic and environmental considerations. With the exponential advancement of technology, unconventional sources of generation, storage and microturbines have been enhanced. The microgrid has paved its way into distributed generation and looks promising for future prospects. A review of microgrid architectures and models is presented in this study. Various control schemes devised for microgrids are also reviewed. The concept of SoSs is introduced and its applications are discussed. A framework is proposed for microgrids from an SoS perspective and control paradigms based on SoS are explained in terms of microgrid control.
