“…Such environments can result in higher operating costs and a higher probability of damage to power equipment used in island microgrids [2]. In addition, the high percentage of renewable energy supply also makes the island power system more vulnerable and reduces the security of island microgrid operations [3]. However, given the importance of islands in marine resources and safety, it is crucial to ensure the safety and flexibility of island microgrid operation.…”

Island microgrids play a crucial role in developing and utilizing offshore renewable energy sources. However, high operation costs and limited operational flexibility are significant challenges. To address these problems, this paper proposes a novel dual−layer distributed optimal operation methodology for islanded microgrids. The lower layer is a distributed control layer that manages multiple controllable distributed fuel−based microturbines (MTs) within the island microgrids. A novel adaptive consensus control method is proposed in this layer to ensure uniform operating status for each MT. Moreover, the proposed method can achieve the total output power of MTs to follow the reference signal provided by the upper layer while ensuring plug−and−play capability for MTs. The upper layer is an optimal scheduling layer that manages various forms of controllable distributed power sources and provides control reference signals for the lower layer. Additionally, a two−stage twin−delayed deterministic policy gradient (MATD3) algorithm is utilized in this layer to minimize the operating costs of island microgrids while ensuring their safe operation. Simulation results demonstrate that the proposed methodology can effectively reduce the operating costs of island microgrids, unify the operational status of MTs, and achieve plug−and−play capability for MTs.

Purpose of Review As we transition to highly renewable energy systems, island energy systems face challenges different from those well-understood for continents. This paper reviews these challenges to guide energy systems modelling for islands. Recent Findings Only a single energy system model is found to be developed especially for islands. Challenges like land scarcity, climate risks, high seasonality of demand, isolation and remoteness, data scarcity, social and political vulnerability, and scarce funding are identified in recent literature. Notably, isolation and remoteness, social and political factors, and insufficient island funding are underrepresented in studies reviewed in this work. Summary This review identifies the specific challenges of island energy systems and compiles the methods employed by researchers to tackle them. We discuss these challenges in detail, highlight gaps, and provide suggestions to improve island energy systems modelling in the future.
