Enhancing the Resilience of Urban Energy Systems in Multi-Energy Micro-grid Via Preventive and Corrective Intelligent Strategies

With the increase of occurrence frequency and severity of power outages, the urban micro-grid is gradually established to resist the impact of emergency events. The multienergy micro-grid (MEMG) can further enhance resilience of urban energy systems, however, the cooperative operation of multi-energy sectors to enhance the resilience needs further optimization in the MEMG. In this paper, the normal operating mode of the multi-energy micro-grid and island operation mode under disaster conditions have been modeled, aiming to minimize costs through the coordinated optimization of operating equipment such as distributed generation (DG), combined heat and power (CHP), storage and so on. Furthermore, we have designed an intelligent overall operational strategy that includes preventive and corrective controls. This strategy optimizes the dispatch of local resources, reducing the curtailment of essential loads during disasters, thereby enhancing the resilience of urban energy systems.
