Abstract
Worldwide legislative, industrial, and technical progress is propelling PEV to dominate the future automobile market. While large-scale simultaneous charging of PEVs can place great pressure on the existing power infrastructure, the PEV, foreseeing the potential in energy delivery with its mobile and energy-storing features, can be utilized to flexibly mitigate grid overload issues. In this article, we discuss the energy management issue in a scenario with strong intersection between transportation and power systems due to enormous PEV deployment. To realize the energy-storing potentials of PEVs, they are used as energy storages to deliver energy among charging stations, referred to as MVESs. By conveying MVES roles in the transportation system, we introduce a joint model of power and transportation systems to quantify the MVES impacts on the on-road traffic. Then, an energy management framework is proposed to mitigate the overload issues with MVESs while guaranteeing time-efficient energy delivery in the transportation system. Modelling and optimization methods are introduced in detail. A case study is conducted to validate the effectiveness of the proposed framework. Finally, we discuss open research issues that can optimize future MVES energy management.
