Renewable energy can cover a growing energy demand. However, can it also ensure system stability when conventional power plants are increasingly being shut down? Large battery storage systems with grid-forming inverters play a key role here. What was previously performed by the inertia mass of the system generators in conventional power plants, is now managed by the power electronics of inverters in the increasingly renewable energy supply. Discover how these technologies contribute to the stabilization of the power grid and how the transition to a 100 percent renewable energy supply can be achieved. <\/strong><\/p>\n

Power plants generate energy and also provide grid-forming capability. In conventional power plants, synchronous machines with rotating inertia masses ensure grid stability by reacting to disturbances. This inertia ensures the grid operation and keeps the grid frequency stable. When these power plants are shut down, battery storage with grid-forming (GFM) inverters can provide these important stabilization functions.<\/p>\n

Another important function for a reliable grid operation is also the grid restoration. The black-start function lets grid-forming inverters with battery storage energy systems start themselves and serve as a starting unit for the restoration of the utility grid after rare extreme events. The power electronics take on the tasks of the synchronous generators.<\/p>\n

The importance of grid-forming inverters<\/strong><\/p>\n

In contrast to the centrally controlled conventional power plants, inverters do not have rotating masses, but the grid-stabilizing functions are programmed using control algorithms. The power electronics of the inverter therefore play a decisive role here.<\/p>\n

The hardware can look the same or similar, while the software enables different functionalities in addition to the normal system functions depending on needs and requirements. A battery can then be used as energy storage to shift the stored energy from midday to the evening. But it is also ready at any time to absorb power peaks in order to keep the frequency stable. Large-scale battery storage power stations in the high and extra-high voltage ranges are already providing stability services.<\/p>\n

Battery storage power stations address the two major challenges of the transformation of the energy system: grid stabilization and relieving the strain on the utility grid.<\/p>\n
