Traditional power systems are facing more and more problems. How to transform?

In order to solve these problems, a new energy power system will appear in the future. The new energy power generation system is a system with high utilization rate of renewable energy. In the future, the basic form of China's new energy power system will be the combination of distribution and centralization, and the combination of long-distance large grid transmission and local consumption of regional microgrid, which is needed by China's national conditions; On the supply side, transmission link and demand side, the horizontal direction is multi-energy complementary, and the vertical direction is the coordinated interaction of source, network, load and energy storage; Realize the power supply response, power grid response and load response, and promote the controllability, safety, stability, informationization, automation and intelligence of the system.

The key technologies and supporting mechanisms of new energy power system include: first, the key technologies and supporting mechanisms of power response, such as grid-friendly power generation technology. There are two types of support mechanisms: strengthening and improving the clean energy compensation mechanism and opening and fair access to the power grid. Second, the key technologies and supporting mechanisms of power grid response, such as new power grid structure and advanced transmission mode, advanced control and security defense technology of power grid, inter-provincial transmission and trading mechanism, and the construction of the whole system. The third is to establish a response mechanism for supply and demand coordination, such as developing intelligent measurement and information systems, intelligent regulation and management systems, big data processing and analysis systems and user terminal equipment, and forming a unified and open equipment standard system.
