Moreover, the inverters are interconnected in parallel with PV cells, facilitating power conversion in a singular-stage configuration. In the traditional structure of solar power plants, inverters and low-frequency transformers are utilized as an interface between PV panels and the AC grid for power transmission.
In the context of PV power plants, the "high-power" classification for multilevel inverters usually applies to systems operating in the MW range, incorporating medium voltage levels of 2.3–13.8 kV to optimize energy transmission efficiency and support reliable system performance .
The critical role of multilevel inverters, particularly Voltage Source Inverters, in the efficient integration and transmission of solar energy into the electrical grid is evident from the challenges and system application needs discussed.
To avoid exceeding the upper vol tage limit, voltage regulation limits are set in the PV inverters. Consequently, the inverter will disconnect the PV supply whenever the upper voltage limit is exceeded. However, dependin g remedied then the PV g enerated power may be completel y cut-off by inverter disconnection. As mandat ed by
Photovoltaic (PV) power generation systems are emerging as a key solution for addressing environmental challenges while satisfying the growing global demand for energy [1, 2]. These systems are highly regarded among renewable energy technologies for their versatility and sustainability.
