Nowadays, Multi-Microgrids (MMGs) systems are emerging as one of the alternatives to enhance resiliency and sustainability of electrical energy systems. In spite of the obvious advantages of MMGs, it is necessary to focus on Energy Management System (EMS) in order to achieve optimal power scheduling and improve power system efficiency. Moreover, the power sharing challenges in MMGs and resiliency issues to maintain power supply for critical loads, especially during extreme event outages, still provide scope for further research. In this regard, a comparison between non-cooperative and cooperative MMGs based, respectively, on decentralized and centralized EMS topologies is presented in this paper. EMSs are developed specifically for a day-ahead optimal and cost-effective scheduling of MMGs. Special emphasis is placed on the minimization of the total operating cost and the resilient operation. Thereby, in cooperative MMGs, reward cost strategies are proposed to promote self-consumption and enhance resiliency. Simulations and analyses are carried out under different scenarios, including normal and outage conditions to highlight the benefits of cooperation between Microgrids (MGs). Ultimately, an evaluation metric is employed to quantify the performances of both MMGs regarding resilience and fault tolerance aspects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
