Tunisia Zero Carbon Smart Microgrid

What is a zero-carbon microgrid?

However, using this kind of energy source will introduce carbon emissions. To achieve the target of carbon neutrality, the concept of zero-carbon microgrid is proposed to indicate a microgrid with zero or nearly zero carbon emissions with the consideration of both power generation to utilization .

What are the development trends of a zero-carbon microgrid?

Then, three development trends of the zero-carbon microgrid are discussed, including an extremely high ratio of clean energy, large-scale energy storage, and an extremely high ratio of power electronic devices. Next, the challenges in achieving the zero-carbon microgrids in terms of feasibility, flexibility, and stability are discussed in detail.

How can microgrids achieve zero carbon goals?

Regarding economic issues, common solutions for achieving zero carbon goals in microgrids often combine distributed energy sources (such as photovoltaics and wind turbines) with energy storage equipment , .

Can low-price energy storage achieve zero-carbon microgrids?

As discussed earlier, large-scale low-price energy storage plays an important role in achieving zero-carbon microgrids, including improving system feasibility, flexibility, and stability. However, such a kind of technology is still missing. Table 2 lists the power ranges and capital costs of PHES, CAES, HES, TES, LABES, and LIBES.

How to optimize power balancing in zero-carbon microgrids?

Optimal power balancing techniques should be studied with the consideration of privacy-preserving in zero-carbon microgrids. Stability analysis and control techniques should be studied especially for the zero-carbon microgrid with grid-forming and grid-following converters.

Are there stability issues in off-grid zero-carbon microgrids?

However, the interactions between these power electronic devices may cause various stability issues , . These issues will be more serious in off-grid zero-carbon microgrids. Few studies have concentrated on solving this issue.
