Researchers of a German faculty of engineering active in the field of power electronics identified the behavior of electrical loads while operating through targeted feed-in of one or more interference signals using a power electronics device connected to the power grid. They also measured electrical characteristics of loads connected to the power grid and continually determined one load sensitivity on the basis of the measured electrical characteristics and the interference signals fed in. At least one of the operating parameters of the power grid was influenced on the basis of the load sensitivity determined. The result is a methodology that works in real time and does not need long history data or complex mathematical methods. Instead the invention provides more accurate control actions in regard of power grids.
The university is offering its methodology worldwide to companies active in the field of power electronics for a license agreement or a research cooperation agreement.
