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 ...

Low-voltage ride through control strategy of permanent magnet direct-driven fan under DC capacitor voltage self-synchronization control

Diance yu yibiao
With the large-scale access of new energy sources such as wind power to the power grid, the inertia of the power system decreases, the frequency modulation ability decreases, and the dynamic performance of the phase locked loop in weak power grid ...
