As a pioneer in energy management and optimization, ABB is a trusted partner in the evolving global energy ecosystem. ABB''s Smart Power solutions are leading energy innovation and transition to new ways of managing the energy, starting
These models should be supported by policies that encourage the application of energy storage technology and the development of microgrids. China''s State Grid and Southern Power Grid have issued "Guiding Opinions
Figure 1 Smart Integrated Energy Microgrid in CSC 1. Strategy 1.1 Innovativeness 1.1.1 Is the innovative concept come from the project itself or other existing programs? With the
Smart Grid presages an advanced power grid that revolutionizes the century-old traditional power grid and the way mankind uses energy. In China, the pressure on the current grid exerted by growing
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.
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.
The future development direction of microgrids in China will therefore be towards an energy system that integrates electricity, gas, water, and heat resources, achieves mutual coupling, and solves the problems of efficient energy utilization and peak regulation .
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.
It is estimated that China will build about 50 distributed energy microgrid demonstration projects by 2025, forming a distributed microgrid technology system, market system and management system.
The key technologies for the development of China’s microgrids that require further special attention are control technology, intelligent protection technology, power electronics technology, renewable energy technology and energy storage technology. (1) Control technology
