This research presents a Maximum Power Point Tracking (MPPT) algorithm for a solar photovoltaic (PV) power station which is constructed based on modified circuit topology of the Modular Multilevel Converter (MMC). The proposed MPPT is featured with Optimized Finite-Control-Set Model Predictive Control (FCS-MPC) to provide continuous extraction of maximum solar energy. The estimation-based approach...
This paper presents a model predictive-based maximum power point tracking (MPPT) method for a photovoltaic energy harvesting system based on a single-stage grid-tied Z-source inverter. First, it provides a brief review of Z-source inverters, MPPT methods and model predictive control. Next, it introduces the proposed model predictive-based MPPT method. Finally, it provides experimental results to verify...
This paper proposes a control scheme composed by a linear control and a predictive algorithm with extended horizon for a three-level neutral-point-clamped (NPC) inverter topology for grid-tie photovoltaic applications. The proposed strategy is capable to balance the capacitor voltages at the DC link and to generate a sinusoidal current at the grid side with a unitary power factor. Differently to other...
