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.

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 Microgrid technology?

It is a small-scale power system with distributed energy resources. To realize the distributed generation potential, adopting a system where the associated loads and generation are considered as a subsystem or a microgrid is essential. In this article, a literature review is made on microgrid technology.

What is a Multiagent System solution to energy management in a microgrid?

A multiagent system solution to energy management in a microgrid, based on distributed hybrid renewable energy generation and distributed consumption, is presented in Reference 220, where, the applied method in controlling the microgrid bus voltage through the multiagent system technique is described.

What is AC microgrid in China?

AC microgrids are most commonly used architecture in China. Several commercial AC micro-grids have been set up in several cities. Wenzhou Nanji of Zhejiang microgrid project was funded as a national “863” demonstration project by National Research Foundation of China. The total investment is about 0.15 billion yuan.

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.
