Under conditions of high renewable energy penetration, the equivalent grid impedance of the inverter, represented by the SCR, is subject to considerable fluctuations, causing the grid to exhibit weak or even ultra-weak characteristics.
Because of its high efficiency and flexible control, inverters are widely used in renewable energy generation. The inverter’s mathematical model is critical in system design and analysis. It is necessary to establish an accurate grid connected inverter model to carry out a reliable load flow analysis calculation.
The function of an inverter is to transform low-quality AC power from the grid or power produced by a DC battery or other intermittent renewable energy sources into high-quality AC power that may be used to power delicate electronic equipment.
R is the equivalent resistance of reactor and converter loss. In the steady state, the harmonic is ignored, and the fundamental component of the AC voltage of the power converter is a sinusoidal waveform with the same frequency as the grid voltage. Therefore, the steady-state equivalent circuit of the converter can be obtained, as shown in Fig. 2.
However, with the widespread parallel connection of grid-connected inverters, particularly in distributed generation systems, the increase in power transmission distances has led to a rise in the equivalent impedance of the grid faced by the inverters, resulting in a significant reduction in the SCR .
