FAQS 4
Do GFL inverters improve grid frequency stabilization?
The testing compared their performance in contributing to the grid frequency stabilization in different IBR ratios and control parameter settings. The results showed that the GFL inverters could improve the frequency stability at an IBR ratio of 60%, but not 80%.
How do GFM inverters work?
Meanwhile, GFM inverters behave as voltage sources and are emerging technologies in bulk power systems. Since their fundamental mechanism maintains their internal voltage constant, they inject active/reactive power rapidly when the grid voltage, i.e., magnitude, frequency, and phase angle, changes due to disturbances.
Does a GFL Inverter Supply constant power?
The inverter model attempts to supply the constant power regardless of the change in grid frequency. The results in Table 3 (a) and (b) show that, for the GFL inverters, all cases with an IBR ratio of 40% or less became “S”, but when the IBR ratio is 60% or higher, cases of “U” or “N/A” occurred depending on the control parameter setting.
What is a GFL inverter?
GFL inverters are inverters with current source characteristics that are widely used today. They attempt to maintain active/reactive power constant in a transient time frame. Hence, the fast power response capabilities are realized by being implemented in control loops outside the fundamental characteristic.
