Toward Resilient Solar-Integrated Distribution Grids: Harnessing the Mobility of Power Sources

In the past decades, weather- and cyber-driven high-impact low-probability (HILP) disasters have been observed more frequently. Mobile power sources (MPSs) including truck-mounted mobile emergency generators, mobile energy storage systems, and electric vehicles have a great potential for enhancing the power system resilience. This paper mainly focuses on investigating the potential roles of the MPS in facilitating a swift restoration of power distribution systems when facing HILP disasters. The distribution system reconfiguration through real-time topology changes is also taken into account to best utilize the network built-in flexibility and help power delivery during emergencies. A mixed-integer nonlinear programming model is proposed for deriving a solution for MPS dispatch and distribution system reconfiguration under a given repair strategy. The model is further linearized into a tractable mix-integer linear programming formulation. Eventually, the coordination of the proposed MPS and photovoltaic (PV) generation is investigated.
