Resilience enhancement of a multi-energy distribution system via joint network reconfiguration and mobile sources scheduling

This paper proposes a new resilience enhancement strategy for a multi-energy distribution system (MDS) through coordinated reconfiguration of the coupled-power-and-heat network, scheduling of mobile power sources (MPSs) as well as the dispatch of stationary distributed energy resources (DERs) including renewable energy generation and energy storage systems (ESSs). Firstly, a resilient-oriented joint network reconfiguration model is proposed for a radial MDS after the disaster. The heat network is formulated as a quasi-linear flow model which is independent of the flow rate and temperature for alleviating computation burdens and reconfiguration. Then, MPSs are dynamically dispatched in the MDS for power exchange with MPS stations, to support the restoration of both the power and heat loads. Thirdly, the whole restoration model is linearized as a mixed-integer linear program (MILP) problem with heterogeneous temporally-spatially, operational, and topology constraints. Finally, numerical case studies are done to validate the effectiveness of the proposed strategy.
