Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity.

This Clock Made Power Grids Possible

Cars That Think

As more power stations adopted the clocks, the frequency regulation allowed them to share electricity and create an interconnected power grid. And Warren, who eventually solved the grid-frequency problem, was actually working on a different puzzle when he came across the answer. How Warren’s clocks regulated grid frequency Henry E.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Second, conventional coal and nuclear plants are being retired for economic and policy reasons, removing stable sources from the grid. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy. Here’s how.

Southern California Edison to buy 261 MW of energy storage projects; largest grid-connected storage purchase in US

Green Car Congress

The new contracts result from a plan recommended by SCE in response to state forecasts of local reliability needs due to the closure of the San Onofre Nuclear Generating Station and anticipated retirement of older, natural gas generation plants along the Southern California coastline that rely on ocean water for their cooling needs.
