This paper presents a delay-compensated modulated model predictive direct power control (DC-M<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>PDPC) strategy for grid-connected three-level neutral-point-clamped (3L-NPC) converters. The proposed method integrates power-oriented control, fixed-frequency modulation, and control delay compensation within a predictive control scheme. The DC-M<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>PDPC strategy achieves fast dynamic response and demonstrates superior steady-state performance in power tracking and DC-link voltage balancing. It also ensures lower harmonic content than conventional methods, even under dynamically varying power conditions, in accordance with the IEEE 519-2022 Standard for Harmonic Control in Electrical Power Systems. These features make it well-suited for grid-tied applications such as wind energy conversion systems (WECS) and photovoltaic (PV) systems.
