Control Strategies for Improving Energy Efficiency and Reliability in Autonomous Microgrids with Communication Constraints

Microgrids are a feasible path to deploy smart grids, an intelligent and highly automated power system. Their operation demands a dedicated communication infrastructure to manage, control and monitor the intermittent sources of energy and loads. Therefore, smart devices will be connected to support...
