Assessment of the Impact of Plug-in Electric Vehicles on Distribution Networks

Abstract

Plug-in electric vehicles (PEVs) present environmental and energy security advantages versus conventional gasoline vehicles. In the near future, the number of plug-in electric vehicles will likely grow significantly in the world. Despite the aforementioned advantages, the connection of PEV to the power grid poses a series of new challenges for electric utilities. This paper proposes a comprehensive approach for evaluating the impact of different levels of PEV penetration on distribution network investment and incremental energy losses. The proposed approach is based on the use of a large-scale distribution planning model which is used to analyze two real distribution areas. Obtained results show that depending on the charging strategies, investment costs can increase up to 15% of total actual distribution network investment costs, and energy losses can increase up to 40% in off-peak hours for a scenario with 60% of total vehicles being PEV.Index Terms-Distribution investment, distribution network planning, electricity distribution, network energy losses, plug-in electric vehicles.

Sustainable Transportation with Electric Vehicles

“…The second method is to exploit the elasticity of charging load and existing communication networks to coordinate and control EV charging, i.e., to enable smart EV charging. This method postpones upgrading or building new charging infrastructure and thus substantially reduces the required reinforcement investment [15,16]. This article focuses on the latter method and studies smart EV charging.…”

An Adaptive Control of Smart Appliances with Peak Shaving Considering EV Penetration

“…The integration of renewable sources increases the generation capacity thus providing more capacity for EVs [6]. However, the impact of EV on distribution network depends on the share of the type of electric vehicle in the network as three types of green vehicles are available in the market: plug-in electric vehicle (PEV), pure battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV) [7]. In order to analyze the impact of electric vehicles on distribution network, the charging demand of EV under different scenarios has been analyzed [8].…”

The Concept of EV’s Intelligent Integrated Station and Its Energy Flow

“…The impact of EVs on distribution networks can be determined by following aspects: driving patterns, charging characteristics, charge timing, and vehicle penetration, etc. [30][31][32]. A significant number of researches have focused on the design and optimization of energy management strategies for EVs [33,34].…”
