What is a microgrid in China?

In 2004, China began to carry out research on the concept of microgrids as proposed by the United States. This research has been based on the connection of distributed generation to large electrical grids via AC (alternating current) microgrids and the impacts of microgrids on large grids.

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

Who operates the power grid in Southwest China?

In Southwest China, the China Southern Power Grid company operates the power grid, investment, construction, and dispatching, and the provincial gas companies are responsible for the operation and dispatching of the gas distribution network.

How does distributed energy work in Southwest China?

Therefore, in Southwest China, the combination of distributed energy with traditional power, energy conversion devices, and flexible loads to form MEGs, and the joint operation with the active DN effectively satisfies the overall objectives of power grid operation.

What are Industrial microgrids?

As a local power grid, industrial microgrids cooperate with large power grids to provide reliable electricity for industries, which reduces electricity costs and industrial greenhouse gas and other air pollutant emissions and improves air quality.

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.
