Research on Regional Vehicle-to-Grid Operation Mode and Optimal Share Planning Model Integrating It Into Electric Power System

Large-scale development of electric vehicles(EV) makes positive contribution in following aspects: ensuring energy securiy,facilitating the formation of new economic growth point and energy-saving and pollutant emission reduction.In this paper the regional vehicle-to-grid operation mode is researched;a regional technical management mode for EV and a market operation mode for EV are constructed;and an optimal planning for grid-connected scale of EV is put forward.According to existing power network structure an intelligent charaging method is proposed,and through a simulation example,a comparative research on the scale of grid-connected EV is performed for three cases: the blind charging,namely the charaging following one’s inclinations,the charging response to TOU pricing and intelligent chargeing.Research results show that under the prerequisite of ensuring power system security and stability,the largest scale of grid-connected charging of EV can be achieved by the proposed modes.Thus,both rationality and advancement of the constructed modes and the proposed optimal planning for grid-connected scale of EV are verified.
