MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641025650 A) filed by Siddharth Institute Of Engineering & Technology, Puttur, Andhra Pradesh, on March 4, for 'tso-optimized dq-pid controlled grid-integrated photovoltaic bidirectional electric vehicle charger with lcl filtering.'
Inventor(s) include R. S. Sai Praveen Kumar; V. Kalyani; C. Aparna; M. Likhitha; S. Venkataramanamma; and T. Vinay.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The increasing adoption of electric vehicles and renewable energy systems has created a demand for efficient and reliable charging infrastructure. This invention presents a grid-integrated photovoltaic based bidirectional electric vehicle charging system employing a Tunicate Swarm Optimization (TSO) optimized DQ-PID control strategy. The system consists of a solar PV array, boost DC-DC converter, DC-link capacitor, three-phase voltage source inverter, LCL filter, and bidirectional battery interface. The PV system generates DC power which is regulated by the boost converter and delivered to the DC-link. A three-phase inverter converts this power into AC and injects it into the utility grid while maintaining high power quality through an LCL filter. A synchronous reference frame DQ-PID controller is implemented for voltage and current regulation, and its parameters are optimized using the Tunicate Swarm Optimization algorithm to reduce voltage ripple, overshoot, and settling time. The system enables efficient bidirectional power flow between the PV system, grid, and EV battery, ensuring stable operation under varying environmental conditions. The proposed approach significantly improves dynamic response and harmonic performance, making it suitable for smart grid based renewable energy integrated EV charging infrastructure."
