6 FAQs about [China s largest AC DC microgrid]

What is the research on DC microgrids in China?

From 2009 to 2016, research on DC microgrids in China has gradually involved many different aspects, such as the study of DC microgrid power electronic converters, DC circuit breakers, and other key equipment, as well as operation control technology, protection, and energy management. 1.2 China’s Current and Planned Policies Regarding MG

What is China doing with AC microgrids?

With the continuous deepening of research, experience has been accumulated in China in the planning and design, operation control and energy management of AC microgrids. In more recent years, Chinese scholars began to simulate DC (direct current) microgrids.

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.

What is an AC/DC hybrid micro-grid?

Current AC distribution networks will remain for the existing AC loads and AC sources. An AC/DC hybrid micro-grid consists of AC sub-grid and DC sub-grid. Each sub-grid has its own micro sources, loads and energy storage equipments. AC sub-grid and DC sub-grid are connected through bidirectional AC/DC converter.

What is AC microgrid?

AC micro-grid AC topology is the earliest microgrid architecture and the corresponding technologies are relatively mature. The AC microgrid usually contains distributed generations, AC and DC loads, energy storage devices and so on. Typical configuration of AC microgrid is shown in Fig. 9.

Is DC micro-grid better than AC grid?

Although DC micro-grid shows several advantages, the connection of AC load and generation is the problem, especially when it is connected to AC grid. On other side, AC network is expected to be dominant for few decades because the existing infrastructures.
