Fraunhofer Institute for Solar Energy Systems ISE
In the topic "Converter-Based Power Grids and System Stability" we research, develop and test the secure operation of our future power grids based on 100% renewable energy.
Power grids are currently changing fundamentally from an electromechanical to a converter-based system. In this context, we are developing methods for the control and stability analysis of decentralized converter-based grids. We are investigating interactions between different power converters, but also between power converters and other grid components. With our concepts for Grid-forming Inverters, we offer solutions that form an important support for the power grid every millisecond.
The verification of these new system services and behaviors is central to reliable grid operation. To this end, we are developing methods, for example to prove the grid-forming behavior of power converters or new grid control methods, which we test with our extensive and high-tech laboratory infrastructure in our Multi-Megawatt Lab.
A key instrument for the transformation of the power grid during the transition phase is the development of grid connection guidelines that define the characteristics of all generators connected to the grid. In order to use the findings in practice, we are actively involved in committees in which grid connection and testing guidelines are developed. We support our partners in implementing the continuously evolving requirements in accordance with the guidelines.
