6 FAQs about [Control system of Inner Mongolia microgrid]

Why is micro-grid important in China?

Micro-grid is becoming an important aspect of future smart grid, which features control flexibility, improved reliability and better power quality. This paper conducts an overview of research and development of micro-grids in China. There are abundant renewable resources in China, which can benefit the development and application of micro-grids.

Why do we need micro-grids?

The integrations of distributed renewable sources in distribution networks lead to the new management, control and operation problems for power systems. It appears that micro-grids can provide better and efficient solutions. There are different definitions for micro-grids.

Why does a microgrid operate in isolated mode?

But when electric energy quality and reliability cannot satisfy the loads demand due to the fault of utility grid, the microgrid will separate from utility grid and operate in isolated mode. In this mode, both microsources and energy storage equipments supply all loads in microgrid .

What is the development process of micro-grids in China?

Similar to other countries, development of micro-grids in China has gone through from the early stage of AC microgrids to the current varieties of AC, DC and hybrid AC/DC micro-girds based on their applications. Many technical problems have been solved and new problems are continuously appeared during the development process.

How a microgrid works?

In grid-connected mode, frequency and amplitude of AC bus is supported by utility grid. When the energy supply from utility grid is enough for all the loads, microgrid can export electric energy to utility grid. Otherwise, microgrid must absorb energy from utility grid. At the same time, the battery is charged through bidirectional AC/DC converter.

Can DC microgrids be used in China?

Although research and applications of DC microgrids in China start later, a good progress has been achieved. In March 2014, China’s first practical building integrated photovoltaic DC microgrid system ran successfully. The DC micro-grid locates at the campus of Xiang’an Energy Engineering, Xiamen University.
