This paper proposes a coordinated topology reconfiguration method for power distribution networks (PDNs) and urban drainage networks (UDNs) to facilitate the load restoration and flood prevention with diversified mobile emergency resources (MERs) under rainstorm disasters. The proposed method synergistically controls the pumps-sluice clusters and drainage rescue vehicles (DRVs) to reconfigure the optimal draining route and flow direction of UDNs for resilience enhancement of PDNs with localized damages. Mobile emergency generators (MEGs) and renewable distributed generations (DGs) are optimally dispatched for supporting PDN reconfiguration to guarantee a reliable electricity supply for UDN drainage facilities under rainstorm-induced transportation interruptions and power outages. Then, a multi-network coupling model with hydrodynamic partial differential equations (PDEs) of pressure and free-surface flows is developed to describe the failure propagation across PDNs, UDNs and urban transportation networks (UTNs). Furthermore, an equivalent transfer matrix of dynamic UDN flows is derived based on Laplace transforms to cope with the PDE-constrained optimization problem for computational burden alleviation. Comparative results have illustrated the superior performance of the proposed method in reducing the critical load curtailment of PDNs and inundation depth of UTN roads.
