In the course of the energy transition, the power grids are undergoing a profound change – from large-scale power plants to small-scale feed-in plants, for example through wind energy or photovoltaic systems in combination with storage systems. Grid forming converters can make an important contribution to voltage and frequency stabilization in conjunction with battery storage, as they behave like a conventional generator on the grid thanks to a special control algorithm. This feature is also called synthetic inertia reserve or virtual rotating mass and provides the power grid with the necessary stability despite decreasing use of conventional power plants, especially in the case of rapidly fluctuating feed-in or reference power.

Benefits:

• Increasing grid stability
• Additional revenue stream by remunerated grid services
• Reduction of CO₂ emissions
