Grid-forming vs. grid-following in residential solar-plus-storage

Scientists at the Bucharest University of Economic Studies in Romania have compared the performance of grid-following (GFL) and grid-forming (GFM) inverters in residential solar-plus-storage systems under low-inertia grid conditions and have found that GFM technology offers significant advantages in terms of grid stability, frequency and voltage recovery, islanding capability, and economic returns, with a relatively short payback period for the additional investment. The researchers explained that most existing studies focus on control design, dynamic stability, and large-scale integration, with ...
