The biggest problem is in the supraharmonics frequency range below 150 kHz where new electrical emission limits are rolled out these years. There is no energy-efficient solution for compatibility of power electronics in this frequency range. That’s a major barrier to realize full electrification.
The new research project will develop tools and devices, which can make current and future power electronic products compatible with the modern power grid, without problems caused by interference. The tools consist of software packages which enable a smoother design process for compliant hardware. One example is black box modeling, that makes it possible to predict interference characteristics of a charger or power converter, even without knowing what’s inside the device.
The project is led by Associate Professor Pooya Davari at the Energy Department at Aalborg University, AAU. The team corporates with Danfoss Drives A/S, Grundfos Holding A/S, Nordic Power Converters Aps (NPC), FORCE Technology and Schaffner EMV AG.
According to Pooya Davari there is an enormous potential in developing power electronic products, which are more compatible with new noise emission limits and with the presence of other power converters on the grid, thus reducing the electrical noise emission on the grid in its entirety.
“We will be able to make products that can be grid-friendly and smoothly integrated to the electrical power grid, while at the same time ensuring their energy and cost-effectiveness. There is no doubt that the Supra-EMC project will be a leap forward for Danish research and development”, says Pooya Davari from AAU Energy.
Funding from Innovation Fund Denmark is crucial to the project, due to requirements of involving various industrial partners and AAU Energy. The potential for reducing interference in energy-efficient electrical power grids is huge. Globally there’s an increasing demand for electricity, which is estimated at reaching 32 000 terawatt-hours by 2030.
