    Abstract
    Plug-in hybrid electric vehicles (PHEVs) present environmental and energy security advantages versus conventional gasoline vehicles. In the near future, the number of PHEVs will likely grow significantly in the world. In spite of the aforementioned advantages, the connection of PHEVs to the power grid may create a series of new challenges for electric utilities. If PHEV penetration exceeds a certain amount it can endanger power system security. In this research, a new charging control scheme which includes both the customer and grid acquiescence is presented. Optimal charging algorithm is developed which minimizes the electrical charging payment of customers. The optimization problem in this...

    , Article IEEE Transactions on Vehicular Technology ; Vol. 63, issue. 7 , September , 2014 , p. 3028-3037 ; ISSN: 189545 Moeini-Aghtaie, M ; Abbaspour, A ; Fotuhi-Firuzabad, M ; Sharif University of Technology
    Abstract
    Societal concerns over global warming issues and dependence on fossil fuels have caused the vehicle market share of plug-in hybrid electric vehicles (PHEVs) to grow. A large penetration of PHEVs, however, would likely put higher stress on power systems. To lessen the PHEVs' harmful impacts on the distribution grid, this paper proposes a two-stage charging control strategy modeled on a renewable-based energy hub. In the first stage, a home-based charging control method is formulated in which the charging cost of PHEVs is considered as an objective. Running this procedure by PHEV schedulers in houses, in the second stage of the proposed strategy, the PHEV coordinator agent (PCA) applies a...

    Microgrid Energy Management with Optimal Operation of Electric Vehicles Parkinglots Considering Technical and Social Aspect

    , M.Sc. Thesis Sharif University of Technology Helmzadeh, Shahrdad (Author) ; Hosseini, Hamid (Supervisor)
    Abstract
    The presence of electric vehicle (EV) parking in distribution or microgrids can become a challenging issue for the power grid. If parking operators charge EVs parked in their parking facilities without coordination with the distribution or microgrid operator, they can impose a heavy burden on the grid, resulting in increased costs and problems in the power network. This study aims to address energy management in EV parking facilities in the distribution network by proposing a two-level model. In this two-level model, the high-level problem is the distribution network, and the low-level problem is the parking facility. At the high-level, the distribution network operator tries to maximize... 

    Optimal allocation of PHEV parking lots to minimize distribution system losses

    , Article IEEE Eindhoven PowerTech, PowerTech 2015 ; 2015 ; 9781479976935 (ISBN) Mazidi, M ; Abbaspour, A ; Fotuhi Firuzabad, M ; Rastegar, M ; Sharif University of Technology
    Abstract
    To tackle the air pollution issues, Plug-in Hybrid Electric Vehicles (PHEVs) are proposed as an appropriate solution. Charging a large amount of PHEV batteries, if not controlled, would have negative impacts on the distribution system. The control process of charging of these vehicles can be centralized in parking lots that may provide a chance for better coordination than the individual charging in houses. In this paper, an optimization-based approach is proposed to determine the optimum PHEV parking capacities in candidate nodes of the distribution system. In so doing, a profile for charging and discharging of PHEVs is developed in order to flatten the network load profile. Then, this...
