New control strategy for grid-forming inverters
Researchers in the United States have created a droop control strategy for grid-forming inverters that purportedly improves power system frequency stability. By using an exponential active power–frequency relationship, the novel technique optimizes the use of available headroom, reduces frequency deviations, and enhances overall grid resilience. Renewable energy resources using grid-forming inverters can actively regulate voltage […]
NREL researchers address safety implications of next-generation battery technologies
Report says new evaluation methods, including AI, will help make future batteries safer. If lithium-ion batteries were once viewed as an expensive energy storage solution with tenuous supply chains, mass production has made them both affordable and readily available for a wide variety of applications. Consumer electronics, electric vehicles and, importantly, battery-based energy storage systems […]
As bidirectional EV charging grows, utility group suggests requiring interconnection
Interconnection of bidirectional EV chargers can enable grid compensation for EV owners while enhancing safety, says a report that offers comprehensive guidance for regulators. The Smart Electric Power Alliance has issued a report advising regulators how to prepare for broader customer adoption of electric vehicles and EV chargers capable of exporting energy from the EV battery to […]
California’s home batteries are replacing gas plants and saving hundreds of millions
The Brattle Group analyzed a gigawatt-hour virtual power plant test that may be the world’s largest as part of its review of California’s distributed peak-shaving program. Battery manufacturing has scaled into the terawatt-hours annually, a breathtaking pace that could soon support multi-day backup of electricity systems. For now, U.S. installations fall far short of what […]
Record nuclear power output in 2024 irrelevant to global energy landscape
Nuclear plants generated a record amount of power in 2024, surpassing record set in 2006, but industry optimism is not backed by economic data or investment, says the World Nuclear Industry Status Report 2025. The World Nuclear Industry Status Report (WNISR) 2025, overseen by French nuclear energy consultant Mycle Schneider, has revealed that global nuclear power […]
