Trusted Data

Today's technologies, techniques, and systems leveraged for managing energy trading operations in electric vehicles fall short in providing operational transparency, immutability, fault tolerance, traceability, and trusted data provenance features. They are centralized and vulnerable to the single point of failure problem, and less trustworthy as they are prone to the data modifications and deletion by adversaries. In this paper, we present the potential advantages of blockchain technology to manage energy trading operations between electric vehicles as it can offer data traceability, immutability, transparency, audit, security, and confidentiality in a fully decentralized manner. We identify and discuss the essential requirements for the successful implementation of blockchain technology to secure energy trading operations among electric vehicles. We present a detailed discussion on the potential opportunities offered by blockchain technology to secure the energy trading operations of electric vehicles. We discuss several blockchain-based research projects and case studies to highlight the practicability of blockchain technology in electric vehicles energy trading. Finally, we identify and discuss open challenges in fulfilling the requirements of electric vehicles energy trading applications.

Dual Scale

With the development of technologies of large capacity batteries and electric vehicles, the number of electric-car will increase dramatically. As a result, disorderly charging will cause a significant impact on the safe and economic operation of power system. Charging load has its adjustability on dual scale of time and space. With this feature, load dispatch in both time and space for dual scale is possible which has a positive effect on the operation of power grid. This paper introduces some recent research achievements on orderly charge control, including electric vehicle charging demand characteristics and load model. Explores the orderly charging, especially the control effectiveness of V2G mode on cases of peak-shift, coordinated operation of new energy, frequency regulation and other aspects. Orderly control strategy for electric vehicles is also put forward. Finally, points out the deficiencies of current research and prospects for future.
