AC smart microgrid structure design

Is ac/dc microgrid a good choice for smart building?

There are ac, dc, and hybrid ac/dc microgrid. However, the single form of dc or ac microgrid cannot realize the efficient utilization of DGs and cannot meet the diversified demand. Therefore, the hybrid ac/dc microgrid architecture is of more value for smart building than single ac or dc forms .

How a microgrid is adapted to a smart building?

The references of active power demand of the ac microgrid and the dc microgrid are obtainable for timely operating detection and control. The IMC strategy is adapted in the proposed architecture of smart building, which has simpler control structure, faster response speed and stronger robustness comparing with existing PI and PR control strategies.

What is smart microgrid concept based AC DC & Hybrid mg architecture?

Smart microgrid concept-based AC, DC, and hybrid-MG architecture is gaining popularity due to the excess use of distributed renewable energy generation (DRE). Looking at the population demand and necessity to reduce the burden, appropriate control methods, with suitable architecture, are considered as the developing research subject in this area.

What is hybrid ac/dc microgrid?

The hybrid ac/dc microgrid. The output stage of the MMC-SST can be regarded as an interlinking converter (IC) between ac microgrid and dc microgrid. The ac bus and the dc bus are connected to the ac interface and the dc interface at this stage, respectively.

What is hybrid microgrid architecture?

The hybrid microgrid architecture contains two sub-grids, i.e., DC and AC sub-grid. In DC sub-grid, the DC DGs (e.g., PV panels), as well as the DC loads (e.g., lights and TVs, etc.) are coupled to the common DC feeder derived from the interface P6.

How can a smart microgrid reduce network costs?

A comprehensive analysis on new structures of AC and DC systems is provided. An intelligent method based on multi-objective particle swarm optimization is used. To increase the availability and reduce network costs, the capacity of a smart microgrid with hybrid RESs is determined. Optimal design of an AC-DC hybrid microgrid is presented.
