Can PV inverters withstand a weak grid?
The coupling of PV inverters connected to the grid through phase-locked loops (PLL) and voltage-current controllers is enhanced in the case of a weak grid. This in turn, brings a series of wide-frequency domain multi-timescale stability problems to the operation of large-scale power plants .
Why does a PV inverter have a series parallel resonance?
When the PV inverter is connected to the grid, series–parallel resonance may occur due to the dynamic interaction between multiple inverters operating in parallel and between the PV inverter and the grid impedance. Consequently, this leads to changes in the output voltage harmonic characteristics of the PV plant.
Do PV inverters have reactive power control?
While IEEE standard 1547 newest version requires PV inverters to have reactive power control, there have been few investigations into the small-signal stability impact of PV inverters on distribution systems especially with reactive power control.
