Abstract

This paper proposes a passivity-based model predictive control (PB-MPC) strategy for a grid-connected photovoltaic system (PVS). The approach combines port-Hamiltonian modeling (pH) with the predictive and constraint-handling capabilities of MPC, preserving the system’s energy structure while enabling explicit constraint management. A discrete-time incremental pH formulation is derived, from which system passivity is theoretically established. The control problem is solved using a single-iteration Newton–Raphson scheme per sampling step, where control input constraints are enforced through projection onto the admissible control set, enabling real-time implementation. Simulation results demonstrate superior performance compared with conventional MPC and Porportional-Integral (PI) controllers, while additional analyzes confirm robustness, computational efficiency, and passivity preservation of the proposed controller. Real-time hardware-in-the-loop (HIL) validation using the OPAL-RT OP4512 platform further demonstrates improved dynamic response and reduced settling time.
