MUMBAI, India, April 20 -- Intellectual Property India has published a patent application (202514092791 A) filed by Ge Vernova Infrastructure Technology Llc, Greenville, U.S.A., on Sept. 26, 2025, for 'system and method for protecting grid-forming inverter based resources from power deviations.'
Inventor(s) include Dustin F. Howard; and Ignacio Vieto Miranda.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "A method for protecting a grid-forming inverter-based resource connected to a power grid from power deviations. The method includes receiving a first feedback signal for a first parameter. The first parameter being one of a power of the grid1forming inverter-based resource or an electrical frequency of the power grid. The method also includes determining a first parameter deviation signal based on a comparison between the first feedback signal and a threshold for the first parameter. Further, the method includes determining a scale factor configured to adjust sensitivity of at least one of a power or frequency protection for the grid-forming inverter-based resource based on a second parameter. The second parameter being another of the power of the grid-forming inverter-based resource or the electrical frequency of the power grid. Moreover, the method includes determining a compensated deviation signal based on the scale factor and the first parameter deviation signal. Furthermore, the method includes determining an accumulated deviation signal over time based on the compensated deviation signal. In addition, the method includes tripping the grid-forming inverter-based resource when the accumulated deviation signal exceeds a trip threshold."
