In 2011, at the beginning of the current electric vehicle (EV) market in the United States, the Electric Power Research Institute (EPRI) published a report [1] detailing certain aspects of the emergence of plug-in electric vehicles (PEVs), including the deployment of charging infrastructure, future impacts on the grid, and potential roles for electric utilities in supporting transportation electrification...
As plug-in electric vehicle (PEV) adoption ramps up, utilities need to maintain grid reliability and safety for adoptors and their residential neighborhood. Quantifying the relationship between electric system distribution equipment capabilities and expected residential PEV charging demand becomes an important utility planning function. PEVs are expected to charge at a rate of 3.3, 6.6, 7.2, 9.6,...
More than 110,000 PEVs are on the road in the United States, and the number of PEVs worldwide is rapidly growing. In parallel the U.S. is reaching the end of a large-scale PEV infrastructure investment. As this round of federal funding ends and these vehicles continue to sell, planning on the national scale will begin. It is important for key stakeholders to understand the number and relative location...
Plug-in Electric Vehicles (PEVs) are now available in many North American and European markets, with more models expected to become available to consumers in the coming years. These vehicles will present utilities with opportunities as well as challenges as their numbers potentially grow to hundreds of thousands of vehicles connected to the electric grid for charging. In order to support PEV adoption...
With plug-in electric vehicles poised to enter the automotive market this year, a remaining concern for electrical distribution utilities is the potential impact these loads may have on their system and how to account for them in their planning process. In order to address this concern, EPRI has initiated a multi-utility project to quantify the potential impacts across numerous distribution feeders...
Accurate assessment of plug-in electric vehicle (PEVs) impacts on distribution system operation requires sufficient understanding and representation of PEV load variations such as daily load shape as well as network location. Traditional distribution system analysis methods cannot always address these variations and therefore not fully describe the PEV impacts on the system. EPRI has initiated a multi-year...
