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.

Why is balancing power/energy important in a zero-carbon microgrid?

There is a very high proportion of renewable power generation in zero-carbon microgrids, and the fluctuation of renewable power makes it difficult to meet the requirements of power/energy balance. Therefore, the research on balancing the power/energy in new power systems is important and has been given much attention.

Will zero-carbon microgrid be a future power system?

Also, few papers have discussed the trends, challenges, and future research prospects for developing the zero-carbon microgrid, an important form of the future power system. This research aims to fill the gaps and point out these important issues.

What is a zero-carbon microgrid?

In off-grid mode, 100% clean energy can be used, and thus zero carbon emissions can be achieved. In this regard, 100% power electronic devices will be generally used in such a microgrid. This kind of zero-carbon microgrid is usually implemented in remote areas and achieved for an entity with small loads . 3.

Which energy storage systems are used in microgrids?

Among the listed energy storage in Table 2, the PHES and LIBES are usually used for large-scale applications in microgrids . However, the first one is limited by geographical conditions and is always used in the main power grid, and the second one still needs high capital costs in zero-carbon microgrids.

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.
