Fraunhofer Institute for Silicon TechnologyWith the closure of nuclear power plants and fossil fuels, the integration of renewable energies and charging stations is becoming essential for climate neutrality. Hybrid grids offer major advantages for decarbonization, but they also pose significant challenges:
- Planning hybrid grids: Successful hybrid grids require careful dimensioning, modeling, and optimal placement of renewable energies and storage facilities, as well as accurate load and generation forecasts to increase efficiency and reduce costs.
- Maintaining grid stability: The integration of renewable energies and charging infrastructure disrupts traditional grid stability, which is based on rotational inertia. Advanced control systems are essential to compensate for voltage and frequency fluctuations.
- Power electronics in hybrid grids: Innovative converter topologies are required to ensure continuous, highly available operation with minimal losses, complete control of power flow, and high power quality, even under overload conditions.
- Power and energy management: Coordinating multiple sources and grid configurations is crucial. Advanced energy management systems, control strategies, and real-time monitoring optimize the performance of the hybrid grid.
