MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641017259 A) filed by Cpgc Pvt. Ltd., Visakhapatnam, Andhra Pradesh, on Feb. 16, for 'enhancement of power quality in a grid connected fuel cell with dstatcom application.'
Inventor(s) include Dr. Akhtar Rasool; Dr. Nitin Suresh Zope; Mr. Aakarshan Pratik Chaurishi; Dr. A. N. Venkateswarlu; Dr. Shanmukha Naga Raju Vonteddu; Dr. P. Magudeshwaran; Mr. Deepak Singh; Dr. Smruti Ranjan Nayak; and Mr. Kandi Bhanu Prakash.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "Electrical distribution systems frequently experience power quality disturbances due to peak load demand, reactive power imbalance, and voltage instability, wherein voltage deviations of 5-10% and voltage sag conditions of up to 20-30% below nominal voltage commonly occur at the distribution level, and reactive power demand may constitute approximately 15-25% of apparent power, thereby reducing power factor and increasing grid stress. Although grid-connected fuel cell systems offer efficient distributed generation with electrical efficiencies ranging between 45% and 60%, conventional inverter interfaces primarily support active power injection and require separate Distribution Static Compensator (DSTATCOM) devices for reactive power compensation, resulting in increased hardware cost and complexity. The present invention discloses a grid-connected fuel cell power quality enhancement system comprising a fuel cell stack, a DC-DC converter, a DC-link capacitor, a voltage source inverter, and a control unit configured to operate the inverter in a dual-function mode to simultaneously deliver active power and provide dynamic reactive power compensation at a point of common coupling (PCC). The control unit incorporates DC-link voltage regulation, synchronous reference frame current control, and voltage sag detection mechanisms to maintain substantially constant RMS voltage at the PCC under varying load and disturbance conditions, thereby eliminating the need for standalone reactive compensation equipment and improving overall power quality and voltage stability."
