MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202631003082 A) filed by National Institute Of Technology, Jamshedpur, Jharkhand, on Jan. 12, for 'method and system for detecting and mitigating cyberattacks in direct current (dc) microgrid.'
Inventor(s) include Kumar, Ashish; Naik, Kethavath Raghavendra; Samal, Simanta Kumar; Nirala, Arvind Kumar; and Prasad, Dr. M. Krishna Siva.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "Provided are a method (300) and system (100) for detecting and mitigating cyberattacks in a Direct Current (DC) microgrid (102). The method comprises preparing (302) a weighted graph corresponding to the DC microgrid (102). Further, the method comprises acquiring (304) real-time electrical measurement signals via a plurality of electrical sensors (103). During operation of the DC microgrid, the method further comprises updating (306) a graph Laplacian matrix constructed from the weighted graph and computing (308) a graph spectral residual by monitoring deviations in the graph Laplacian matrix. Simultaneously, the method comprises estimating (312) physically consistent clean system states of the DC microgrids through a physics-informed neural network (PINN) estimator. Thereby, the method comprises computing (314) a physics residual from the PINN estimator, and determining (316) a presence of a cyberattack when both the graph spectral residual and the physics residual exceed corresponding predefined threshold value, and executing (318) adaptive mitigation."
