  Mobile energy resources (MERs) have received increasing attention due to
their effectiveness in boosting the power system resilience in a flexible way.
In this paper, a novel mobility model for MERs is proposed, which can support
the routing of MERs to provide various services for the power system. Two key
points, the state transitions and travel time of MERs, are formulated by linear
constraints. The feasibility of the proposed model, especially its advantages
in model size and computational efficiency for the routing of MERs among many
nodes with a small time span, is demonstrated by a series of tests.
