MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202531083019 A) filed by Indian Institute Of Technology, Kharagpur, West Bengal, on Sept. 1, 2025, for 'control reconfiguration in photovoltaic inverters for inertia and stability support..'
Inventor(s) include Supratik Bhowmick; and Chandan Chakraborty.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides a method for reconfigurable optimized control of grid-following (GFL) and grid-forming (GFM) modes in a photovoltaic (PV)-fed grid-connected inverter, comprising involving individual GFL and GFM modes in a control architecture that operates the inverter to follow characteristics of either individual GFL and GFM control modes or a combination of both the modes through adjustment of a single "reconfigurable control factor" or "r-factor", determining grid short circuit ratio (SCR) from frequency parameters of the grid, and computing optimal value of the r-factor for achieving an optimal reconfiguration between GFL and GFM modes depending on the SCR determination including considering minimum deviations in both DC link voltage and grid frequency at any particular SCR operation of the grid."
