MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202531133277 A) filed by National Institute Of Technology, Rourkela, Orissa, on Dec. 30, 2025, for 'system and method for cyber-resilient frequency regulation in islanded microgrid.'
Inventor(s) include Ray, Dr. Pravat Kumar; Khamari, Mr. Ramesh Chandra; Senapati, Dr. Manoj Kumar; and Padmanaban, Dr. Sanjeev Kumar.
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 relates to a cyber-resilient microgrid frequency regulation system (200) and method (100) for cyber-resilient frequency regulation in an islanded microgrid. The system (200) comprises an islanded alternate current (AC) microgrid comprising a plurality of power generation units, renewable energy sources, and energy storage systems (ESS), a communication network configured to transmit measurement and control signals to the generation units, an adaptive secondary frequency control mechanism comprising a fractional order proportional-integral-derivative (FOPID) controller, the secondary frequency control mechanism is configured to regulate microgrid frequency under cyber-attack conditions such as time-delay attacks, disturbances in the ESS, false data injection attacks, random attacks, and malware attacks, a modified improved whale optimization (MIWO) algorithm configured to calculate tuned control signals, and fractional-order parameters of the FOPID controller in real-time, the system (200) provides frequency stability despite variations in energy ESS availability."
