Stability-Oriented Minimum Switching/Sampling Frequency for Cyber-Physical Systems: Grid-Connected Inverters Under Weak Grid

Abstract: Although the cyber-physical system stability is widely studied, scholars focus more on system stability with communication time delay. Therein, grid-connected inverters with the digital control system are regarded as one simplest and typical cyber-physical system. Meanwhile, the switching/sampling frequency of the inverter is always selected as low as possible from an efficiency viewpoint, resulting in unavoidable delay time. This delay time is apt to cause the system instability, which is more prone to severi… Show more

“…The control method proposed in References 15 and 13 can improve the power quality of the DDN system and realize power sharing among distributed power sources. In recent years, previous studies have been conducted on the distributed control of PV power generation units in DC MG. 14,16,17 Meanwhile, distributed control methods involving consensus theory have been applied to load control, 5 economic scheduling problem, 18,19 voltage and frequency adjustment and other fields in power system.…”
