Abstract

Advances in renewable energy technologies and power electronics in addition to environmental and economic factors have motivated a paradigm shift in the design of future power delivery systems. This article empathizes the need to incorporate resilience elements within distribution systems design to enable autonomous adaptive operation through different cyber and physical disruptions. A cooperative game-theoretic approach is proposed to enable interconnected microgrids (MGs) to coordinate their aggregate energy requirements for an improved utilization of intermittent renewable energy resources and distributed storage systems. An adaptive distributed algorithm is developed for MG networks with physical constraints, line outages, and distributed energy resources with varying renewable penetration levels and energy mixes. The enhanced resilience is demonstrated through the study of the IEEE 34-node test feeder system, where cooperation achieves substantial gains and is able to naturally adapt to and recover from extreme disturbances.
