Utilizing PHEVs for Peak-Shaving, Loss Reduction and Voltage Profile Improvement via V2B Mode

Plug-in hybrid electric vehicles (PHEVs), provide an option to use the stored energy in their batteries to support the electricity grid. The vehicle-to-grid (V2G) mode of PHEVs have been investigated in numerous recent studies from many aspects, while most of them have predicted a 10- to 15-year horizon for V2G to gain a wider acceptance of governments and stakeholders who are interested in changing existing electricity grid to a smart grid. Thus, electricity grid should be focused on a more practical examination and implementation before reaching that point. Vehicle-to-building (V2B) mode is a concept that could be broadly implemented on a horizon of less than 4 years. Disconnecting home or whole a facility from grid, is the greatest excellence of V2B. In this paper a real distribution network is modeled in order to analyze the constructive potential profits of PHEVs as dispersed energy storage, performing on V2B mode of operating. The proposed model is a real domestic distribution network with 990 customers, which the impacts of V2B mode of PHEVs from the aspects of power loss, delivered voltage profile and load peak shaving have been simulated.
