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.
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 provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.
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.
