Revolutionary inverter technology: the end of the large power plants?
In a time when wind and solar power plants are increasingly replacing fossil and atomic power plants, the stability of the power grid is becoming increasingly important. This requires a stable clock for electricity voltage and frequency, a function that has so far been mainly provided by large fossil mega power plants and nuclear power plants. Researchers of ETH Zurich have now developed to stabilize the network. This innovative solution is based on an algorithm that actively stabilizes the network frequency and limits electricity transmission during instabilities.
Simulations of the new control have already achieved very satisfactory results. The algorithm allows the inverters to react directly to turbulence online and compensate for them. So far, inverters separated independently from the network in the event of failures or instabilities. With the new system, however, you can continue to supply electricity and contribute to stabilizing the network frequency, even if there are errors on the network.
new technologies for the future
The new network -forming inverter could play a crucial role in the future power grid. ETH engineers have developed algorithms that make it possible for inverting to remain active in network errors. This means that wind power and photovoltaic systems can take on the tasks of the classic large power plants by continuously measuring network parameters and adapting them in real time. This technology is an important step towards a decentralized power grid without large fossil or nuclear power plants.
The ETH Zurich has registered the new algorithms for a patent and works closely with industrial partners to support the implementation of these technologies. ETH students should carry out their master's theses in industrial companies in order to put these new approaches into practice. This initiative could help reduce the risk of blackouts and to promote sustainable energy future.
The view of the future of energy supply
The development of an algorithm to stabilize the power grid shows how the energy systems change. The use of interverters with new technologies could be crucial for ensuring that network stability is also guaranteed in times of decentralized energy generation. In addition, the reserve keeping of old power plants is no longer necessary, which creates space for flexible and sustainable energy supply.
The challenges and opportunities of the energy transition require continuous research and development in power electronics. As already Fraunhofer ISE , flexible and reliable inverter circuits for ensuring a stable energy supply in the future are. The combination of renewable energies with innovative technologies is the focus of the development of a resilient power grid that meets the requirements of a modernized energy environment.
