NREL study finds that uncoordinated plug-in vehicle charging could prove challenging to the grid

Green Car Congress

An influx of plug-in electric vehicles (PEVs) charging without coordination could prove challenging to the nation’s electric grid, according to research conducted by the US Department of Energy’s National Renewable Energy Laboratory (NREL). Muratori noted that might be true in the future, but not necessarily.

This Dutch City Is Road-Testing Vehicle-to-Grid Tech

Cars That Think

Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses. Debates over the feasibility and value of such vehicle-to-grid technology go back decades. This is good for the grid.

How to Prevent a Power Outage From Becoming a Crisis

Cars That Think

There are technical reasons that contributed to faster repairs in Manhattan, but in general the neighborhoods that waited the longest to have their power restored tended to be poorer and less white. And it slowed urgent repair and maintenance of the power grid, with work crews having to practice social distancing due to the pandemic.

Study: Reducing Future Transportation CO2 Emissions to Kyoto Protocol Levels Will Require Combination of Vehicle Technology and Smart Growth

Green Car Congress

The BAU scenario assumes future population and land use trends throughout the study region will be consistent with historical change. The core of the study’s approach is a vehicle activity modeling framework for associating future land use and demographic characteristics, under BAU, SG1, and SG2 scenarios, with household vehicle travel.
