Abstract
Recently, with the growth and development of distributed generation (DGs) and energy storage systems (ESSs), as well as smart control equipment, microgrids (MGs) have been developed. Microgrids are comprised of a limited number of constitutive parts, including loads, DGs, ESSs, and electric vehicles (EVs). This paper presents a novel scheme to manage active and reactive powers, based on DGs, ESSs, and EVs to reduce the total operation cost including power generation and emission costs. Simultaneous management of active and reactive power makes it possible to consider grid operation constraints together. In the proposed schedule, the vehicles are assumed to be plug-in hybrid electric...

Microgrid Energy Management with Optimal Operation of Electric Vehicles Parkinglots Considering Technical and Social Aspect
, M.Sc. Thesis Sharif University of Technology ; 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...

Online multicriteria framework for charging management of PHEVs
, Article IEEE Transactions on Vehicular Technology ; Vol. 63, issue. 7 , September , 2014 , p. 3028-3037 ; ISSN: 189545 ; 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...
