Decentralized Multi-Time Scale Power Control for a Hybrid AC/DC Microgrid With Multiple Subgrids

A Hierarchical Self-Regulation Control for Economic Operation of AC/DC Hybrid Microgrid With Hydrogen Energy Storage System

“…However, renewable energy generation has inherent characteristics of uncertainty and intermittence, which remains obstacles of its application [3]- [5]. AC/DC hybrid microgrid is an effective solution to supply different AC and DC loads, and simultaneously to integrate with renewable energy sources (RESs) efficiently and reliably [6]- [8].…”

Adjustable Inertial Response From the Converter With Adaptive Droop Control in DC Grids

“…Some modified droop controllers have been presented recently to further enhance the voltage quality and stability of DC grids [22][23][24][25][26][27]. In [22], an improved decentralized DC power management strategy based on P-Vdc 2 droop is designed to enhance the dynamics of DC power regulation.…”

“…In [22], an improved decentralized DC power management strategy based on P-Vdc 2 droop is designed to enhance the dynamics of DC power regulation. In [23], a droop controller suitable for multitime scale power control is presented to realize proper power interaction among different sub-grids. In [24], the relationship between AC frequency and DC voltage identified via the interactive virtual inertia and capacitance is used to design the voltage control strategy for AC/DC interface for improving the system stability.…”

Flexible control of DC interlinked multiple MGs cluster

“…With such a hybrid unit, an AC MG could be connected to a common DC bus via modular multilevel converters based DC interface. Xia et al in [15, 16] also proposed a flexible interconnection structure for multiple MGs based on a common DC bus, as shown in Fig. 1, in which these AC MGs and DC MGs had been connected to the common DC bus by bi‐directional DC–AC converters and bi‐directional DC–DC converters, respectively.…”
