Dynamic load restoration considering the interdependencies between power distribution systems and urban transportation systems
mobile emergency resources (MERs) can be dispatched via the transportation system (TS) for service restoration to critical loads in the power distribution system (PDS). In this case study
the efficiency of service restoration in the PDS is associated with the traffic efficiency of the TS
and vice versa
because the PDS and TS are mutually coupled through traffic lights and MERs. This paper proposes a service restoration method considering interdependency between the PDS and TS
which is formulated as a mixed-integer linear program (MILP). The objective includes maximizing the efficiency of both PDS restoration and TS. By solving the MILP
the dynamic load restoration and MER dispatch strategies can be obtained. For the PDS
the availability of MERs
including mobile sources and repair crews
relates to their dispatch in the TS
and their relationship is formulated as mathematical models. For the TS
the dynamic traffic flow is modeled using the cell transmission model and the effect of traffic lights is considered. Case studies validate the effectiveness of the proposed method.
