In the comparison between the improved inverter adaptive control system and the inverter adaptive system, the improved inverter voltage recovery speed is faster, can be restored within one cycle, and the control effect of the inverter is better. The harmonic rate of the port voltage has decreased from 10.43 to 1.92%.
This paper proposes a robust voltage control strategy for grid-forming (GFM) inverters in distribution networks to achieve power support and voltage optimization. Specifically, the GFM control approach primarily consists of a power synchronization loop, a voltage feedforward loop, and a current control loop.
At 0.25 s, the harmonics showed a significant decrease, dropping to 10.43%. Figure 10 b shows the voltage variation under adaptive control, with harmonics decreasing to 1.92% at 0.25 s. The improved inverter has better control effect because it effectively solves the problem of high harmonics. Figure 11 shows the control effect of voltage.
These systems often require the capability to operate either connected to the main grid or in islanded mode where inverters also help control voltage, frequency, and power flow, ensuring stable and efficient integration of renewable energy into the grid.
