This article provides a comprehensive overview of hierarchical control methods that ensure efficient and robust control for MGs. Specifically, it focuses on the secondary controller approaches (centralized, distributed, and decentralized control) and examines their primary. . ifferent control architectures for the secondary control (SC) layer. The use of new SC architectures involving CI is motivated by the need to increase MG resilience and h ndle the intermittent nature of distributed generation units (DGUs). In our setting, the output voltage and frequency of the inverters is determined by a primary control scheme realized through. . A microgrid (MG) is a small-scale power system capable of operating independently or in conjunction with the main power grid. MGs can operate in two modes: grid-connected and. .
