  Power packet dispatching system has been proposed for smart power management
in the form of discretized packet. In this paper, we discuss the routing
optimization of power packets on the network of power routers. We propose a
cost metric for the power packet delivery by circuit analysis of the router
network. Using the metric, we formulate the optimization problem as a general
shortest path problem from a source node to a load node. The result of
numerical simulations shows that the proposed algorithm can allocate
distributed power sources to load demands and identify the optimal path for the
power delivery.
