MIT team studies grid impacts of concentrated highway EV fast charging

Green Car Congress

Researchers at the MIT Energy Initiative have investigated the grid impacts of scaled up highway fast-charging (HFC) infrastructure by using an operations model of the 2033 Texas power grid with uniquely high spatial and temporal resolution. Greater impacts are observed for higher EV penetration cases—up to $6/MWh.

How everyday people can help reduce the need for fossil fuels on hot days!

Green Energy Consumers

Shave the Peak is our program designed to inform people, via text and email alerts, how and when to reduce power use on days when demand for electricity is significantly higher than usual or average. Oftentimes, the New England power system sees demand peaking just as solar power production tails off at dusk and it’s still hot.

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario. —Weis et al.

AC vs. DC Power: What's the Difference for Electric Vehicles?

EV Connect

Another important factor to consider for EV charging is the power current. Electric vehicle charging stations use both alternating current (AC) and direct current (DC) to power EVs. Read on to learn about the differences between both types of electric power, as well as the pros and cons of each.

BMW Group plants stepping up activities in balancing-power market to contribute to grid stability

Green Car Congress

The energy control stations at BMW Group Plants Dingolfing and Landshut are stepping up their activities in the balancing-power market in Germany. Together with other highly-flexible controllable systems in the BMW Group production network, they will contribute to the stability of the public grid outside of the plant. Source: neon.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy.
