What is es unit in a dc microgrid?
Among these components, the ES unit is crucial for maintaining the stability of the DC microgrid system. It is responsible for ensuring DC bus voltage stability and suppressing power fluctuations in the grid. The DC microgrid under consideration in this paper comprises PV micro-sources and hybrid ES units.
How to improve dc microgrid system stability?
Improving DC microgrid system stability, numerous scholars have investigated various control strategies for each unit within the system, including droop control, master-slave control, and hierarchical control. 9,10 However, these control methods have been ineffective in enhancing the microgrid’s inertia.
How does vdcm control affect es converter response speed?
The analysis of simulation results yields the following conclusions: VDCM control imbues the ES converter with DC motor-like dynamic characteristics. Increasing the inertia coefficient J and damping coefficient D can enhance the stability of the system; however, choosing excessively high values may impair the system’s response speed.
Can vdcm control improve inertia and damping in DC microgrids?
Inspired by VSG technology in AC microgrid control, 13–15 scholars domestically and internationally commenced research into virtual inertia control in DC microgrids, ultimately leading to the proposal of VDCM control. The objective of this research was to improve the inertia and damping in DC microgrids through VDCM control implementation. 16,17
How fast does DC bus voltage recover?
Similarly, during sudden load power increases, the DC bus voltage drops by 9.7 V, recovering in 2.078 s under conventional control. The proposed strategy limits the voltage fluctuation to 5.2 V with a recovery time of 2.048 s. Figures 15 (c) and 15 (d) show the change curves corresponding to J and D, respectively.
