In this paper, the explicit state-space model for a multi-inverter system including grid-following inverter-based generators (IBGs) and grid-forming IBGs is developed by the two-level component connection method (CCM), which modularized inverter control blocks at the primary level and IBGs at the secondary level.
However, the critical point and stability margin for grid-forming inverters have not been clearly defined. Additionally, most of the converter-driven power system stability analyses are based on single machine infinite bus (SMIB) scenario, where the system is equivalent to a voltage source with impedances behind.
The characteristics of different communication methods of inverters are obvious, and the application scenarios are different. In order to better weave the underlying network of energy digitization and intelligent development, choose the most appropriate communication method according to local conditions.
In contrast, previous experiments in and numerical analysis in show that grid-forming inverters gradually exhibit worse stability in stiff grid. This is logically reasonable as in the extreme circumstance that voltage- controlled grid-forming inverters cannot manipulate voltage at the infinite bus .
Step changes in the inverter’s reference power show the strategy’s quick adaptation to reactive power demands, while maintaining a stable active power supply. Furthermore, active power control disconnects the BESS when it approaches its lower SoC limit in a near-depleted battery scenario.
