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.
The typical application scenarios in China cover areas such as residential community, commercial buildings, commercial and industrial parks, and universities. All of these microgrid projects contain renewable energy generations, such as PV and wind units, which promote the near-end consumption of renewable energy. Table 1.
Project structure The Dongao Island megawatt-level independent smart microgrid project was China's first megawatt-level microgrid system with complementary wind, solar, diesel, and energy storage, and was also China's first commercial-run island smart microgrid system. The project was constructed in two phases.
Microgrids can accept a high proportion of renewable energy and support users' flexible energy use and flexible transactions around energy sales and purchases. Figure 5 shows the market scale forecast for deployment of China's energy Internet in the future.
Finally, in recent years, China continues to formulate new policies to encourage the construction and development of micro-grid. “The National Energy Board will build 30 micro-grids demonstration project during “the twelfth 5-year”. Preliminary estimates by 2015, China's investment on microgrid will reach 3.167 billion yuan.” reported in .
