Abstract:
Smart distribution systems are critical cyber-physical energy systems that consists of multiple networked microgrids (MGs) with a distributed architecture. The main problem behind these cyber-physical energy systems is how to manage energy sources to have an efficient and economic energy supply. This paper proposes a cooperative energy management software (EMS) for networked microgrids (MGs) by explicitly modeling the cooperative behavior of MGs. The network of MGs is autonomously self-organized into multiple stable coalitions to achieve an efficient and economic energy exchange. The coalition consists of several MGs that exchange energy with a competitive energy prices to maximize their utility. We formulate the problem of energy management in networked MGs by a coalition formation game between MGs. We develop a merge-and-split-based coalition formation (MSCF) algorithm to ensure the stability of the formed coalitions and maximize the profits of MGs. Then, we design an intra coaliti
on energy transfer (ICET) algorithm for transferring energy between MGs within the same coalition to minimize power loss. The simulation results demonstrate a satisfactory performance in terms of profit maximization that exceeds 21% and in terms of power loss reduction that exceeds 51%, thanks to the proposed cooperative energy management software.
