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 .
At the distribution grid level, the PV inverters are controlled to reduce the system's active power loss and to address problems caused by the PV systems themselves. For example, the distribution grid may face overvoltages due to high PV generation during off-peak hours.
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 proposed model, by examining weather conditions and the amount of solar radiation during different hours of the day, a droop control has been presented for inverters to store reactive power in the specified grid.
High voltage capability opens up a broader range of compatible components, allowing system designers to optimize performance. It enables the use of more efficient and cost-effective
