Optimal Policy for Plug-in Hybrid Electric Vehicles Charging Station Scheduling Problem

Advances in the development of electric vehicles along with policy incentives will see a wider uptake of this technology in the transport sector in the coming years. However, the widespread adoption of electric vehicles will add a substantial energy load to power grids. As a result, many technical problems related to the impact of this technology on the power grid need to be addressed, especially the management and allocation of the energy to the plug-in hybrid electric vehicles (PHEVs), electric vehicles (PEVs). In this paper, we formulated the optimal power allocation to PHEVs/PEVs for the PHEVs/PEVs charging stations scheduling problem as a nonlinear resource allocation continuous problem. We used pegging algorithm to solve the optimal power allocation to the PHEVs/PEVs. A mathematical framework for the objective function (i.e., minimizing the average depth of discharge (DoD) at the next time step) was also given. The authors characterized the performance of optimal power allocation to PHEVs/PEVs problem and pegging algorithm using MATLAB simulation, and compared it with other charging methods.
