Swiss researchers developing control algorithm for grid-forming inverters

Researchers at ETH Zurich have patented a grid-forming inverter algorithm that stabilizes frequency while protecting devices from damage by independently controlling frequency, voltage, and current.From pv magazine Germany A research team from Swiss research institute ETH Zurich has created a new algorithm for operating inverters in a grid-forming mode. The patented algorithm operates the inverter as a voltage source, which is critical when shor…

Researchers at ETH Zurich have developed new algorithms that can keep the European electricity grid stable even without conventional large-scale power plants. They help to ensure that inverters are the clocks in the electricity grid in the future. This makes them a guarantee of security of supply – even if more and more wind and solar power plants supply the electricity. The article Security of supply: New clocks for the electricity grid found f…

Especially in the case of grid malfunctions, the network-forming properties of inverters are difficult to implement if they have any. A team at ETH Zurich developed a new approach whereby frequency, voltage and current are considered separately. Thus, the frequencies are kept stable and the devices are protected from damage at the same time.There is a new algorithm to operate inverters grid-forming. The algorithm operates the inverter as a volta…
