The Development and Key Technologies of Smart Distribution Network Planning Converging High Penetration Level of EVs

As an effective way to solve energy problems and achieve sustainable development, electric vehicles (EVs) present broad application prospects. Without the help of effective distribution network planning and design methods, the development of EVs is impossible. However, due to the massive access of EVs, the planning and design of distribution network is quite different from the traditional power system. This paper presents the key steps of smart distribution network planning converging high penetration level of EVs on the technique side, reviews latest developments in the field of modelling methods, solving algorithms and evaluation methods, and emphatically discusses the coupling between the EVs' charging behavior and the planning of distribution network, as well as the main comprehensive evaluation methods. The future research direction of smart distribution network with high-penetration level of EVs is proposed.
