MUMBAI, India, June 6 -- Intellectual Property India has published a patent application (202517046731 A) filed by General Electric Renovables Espana S. L., Barcelona, Spain, on May 15, for 'system and method for providing blackstart of grid-forming inverter-based resources.'
Inventor(s) include Tiwari, Arvind Kumar; Padmarao, Veena; Jha, Kapil; Roy, Rabisankar; and Tatikonda, Subbarao.
The application for the patent was published on June 6, under issue no. 23/2025.
According to the abstract released by the Intellectual Property India: "A method of synchronized blackstart in a power generating farm connected to an electrical grid includes selecting, at least, a subset of a plurality of inverter-based resources at the power generating farm having grid forming capability and an anchor power generating asset that are capable of contributing to the blackstart based on one or more parameters. The plurality of inverter-based resources are connected to the electrical grid via a transmission network. The method includes utilizing the grid forming capability of the subset of the plurality of inverter-based resources for initial start-up to bring the subset of the plurality of inverter-based resources online and form a plurality of islands, thereby partially re-energizing the transmission network and enabling restoration of one or more critical loads within a first time period during the blackstart. During a subsequent, second time period, the method includes further energizing the transmission network to fully restore the electrical grid to normal operation."
The patent application was internationally filed on Nov. 21, 2022, under International application No.PCT/US2022/050533.
