Low voltage ride through (LVRT) enhancement of a two-stage grid-connected photovoltaic system based on finite-control-set model predictive control strategy

International Journal of Renewable Energy Development
Grid-connected photovoltaic (PV) systems face numerous challenges during grid faults, including fault detection, synchronization, over-current protection, fluctuations in DC-link voltage, and compliance with active and reactive power requirements. This paper presents a control strategy based on finite-control set model predictive control (FCS-MPC) to ...
