Aiming at solving the problem of new energy and load uncertainty leading to a steep increase in demand for flexible reserve resources by integrated service providers (IESPs), coordinated optimized scheduling method multi-region considering is proposed. First, load, Latin hypercube sampling used generate scenarios, scenarios are reduced K-means clustering algorithm. Second, based on interaction relationship between active distribution network (ADN) IESPs, mixed game model ADN IESP alliance established. guides IESPs optimize their operation setting prices electricity reserves, fully tap own according set achieve power interoperability through multiple regions synergistically cope with uncertainties load. Finally, example results show that proposed this paper able realize allocation flexibility wider range, reduce pressure superior grid, improve profitability IESPs.

Island communities that depend on mainland grid connections face substantial risks when natural disasters sever undersea or overhead cables, often resulting in long-lasting outages. This paper presents a comprehensive and novel two-part methodological framework for enhancing the resilience of these through networked microgrids interconnect local renewable energy resources battery storage. The integrates techno-economic capacity optimization using HOMER Pro with agent-based simulation AnyLogic to determine cost-effective solar storage capacities model dynamic real-time dispatch under varying conditions. Six island across three Indonesian provinces serve as illustrative case studies, tested best-case worst-case disruption scenarios reflect seasonal extremes availability. Simulation results reveal isolated expansions PV can ensure critical residential loads, though certain islands limited continue experience shortfalls. By contrast, enable surplus power transfers between islands, significantly reducing unmet demand alleviating need large-scale, individual These findings demonstrate significant potential clustered microgrid designs improve reliability, lower operational costs, facilitate secure supply even during prolonged cable proposed offers scalable roadmap deploying resilient clusters remote regions, direct policy implications system planners stakeholders seeking leverage high-risk environments.

Hydrogen energy plays an increasingly vital role in global transformation. However, existing electric–hydrogen coupled integrated systems (IESs) face two main challenges: achieving stable operation when with large-scale networks and integrating optimal dispatching code physical systems. This paper conducted comprehensive modeling, optimization joint simulation verification of the above IES. Firstly, a low-carbon economic model IES considering carbon capture power plants is established at layer. Secondly, by organizing selecting representative data dispatch model, planning integration wind, photovoltaic (PV), diesel storage constructed The proposed coupling mainly consists following components: alkaline electrolyzer, high-pressure hydrogen tank compressor proton exchange membrane fuel cell. this achieved mode system can maintain control despite unpredictable changes renewable sources, showing strong resilience reliability. also integrate for operation, enhancing utilization absorption PV wind power. Co-simulation showed that optimized has 29.42% reduction total cost 83.66% decrease emissions. Meanwhile, proved system’s harmonic distortion rate controlled below 3% both grid-connected islanded modes, indicating good quality.
