How grid-forming inverters may enhance grid synchronization

US researchers have investigated how grid-forming inverters could help to resolve network synchronization issues. They have found that multi-loop devices could offer strong damping support in power systems with intermittent renewables.


MIT, NREL researchers develop 40%-efficient thermophotovoltaic cell for grid-scale thermal batteries

The device is described as a heat engine with no moving parts that is able to produce power from a heat source of between 1,900 to 2,400 C. This concept is known as thermal energy grid storage (TEGS) and consists of a low-cost, grid-scale storage technology that uses thermophotovoltaic cells to convert heat to electricity above 2,000 C.
