ABSTRACT With increasing renewable energy penetration and more frequent extreme weather events, fault occurrences in distribution networks (DNs) have risen significantly, highlighting the urgent need to enhance distribution system resilience. However, existing fault recovery strategies are constrained by the lack of a coordinated scheduling mechanism across multiple resource types. To address this limitation, this paper proposes a source–grid–load (SGL) coordinated resilience enhancement strategy that leverages the spatiotemporal flexibility of data centre (DC) resources. A comprehensive SGL scheduling framework is established: on the source side, a mobile emergency generator (MEG) dispatch model is developed for rapid active power support; on the grid side, a coordinated optimisation model for network reconfiguration and islanding is formulated to enhance topological adaptability; on the load side, a DC workload migration model is proposed to flexibly regulate demand. A multiobjective optimisation problem is then constructed to minimise load shedding and DC operating costs, which is linearised and convexified for tractable solving. Case studies conducted on modified IEEE 33‐bus and PG&E 69‐bus systems under various fault scenarios validate the proposed method. Comparative results show that the SGL‐coordinated strategy significantly improves DN resilience and operational efficiency.
