ECN (in a consortium with TenneT TSO, CG Power Systems, Energy Solutions, TU Delft and TU Eindhoven) is kicking off the project ‘Large Offshore Wind farm Harmonics Mitigation’ LOW-HarM, to increase electricity system sustainability.
Harmonics are distortions of the voltages and currents in the electricity grid. High harmonic levels can cause extra energy losses, tripping of protection systems and contribute to premature component failure. Modern wind farms include many power electronic converters and long offshore cables that are sensitive to these disturbances. These problems can be solved but today’s design approach is on a case-by-case basis and often leads to delays and price increases and also holds risks for future offshore wind farms.
The project consortium will work towards a more standardized, future-proof and cost-effective design approach that will increase the reliability and efficiency of offshore wind. Together with new interface requirements and best practices, the results contribute to accelerate the energy transition and reduce integration costs.
The project is coordinated by ECN and is supported by the TKI Wind op Zee program.
