After three years of scientific and technological breakthroughs, the project team is engaged in large-scale intermittent new energy grid operation control and intelligent dispatching technology, interaction technology of grid and electric vehicle charging and discharging facilities, efficient and reliable power distribution and microgrid technology, and diversified user flexibility. In the field of interactive technologies, a number of innovative research results with independent intellectual property rights have been obtained, and 18 demonstration applications have been formed, which have promoted the upgrading and striding of our country's power grids from traditional power grids to efficient, economical, clean and interactive modern power grids.
Completed research on key technologies such as distributed generation access with wind and solar storage and large-scale access to multi-featured small hydropower groups. In Hainan, the demonstration of multi-type new energy power generation and consumption technologies with intermittent energy penetration rate of not less than 15% was achieved. Application: Completed research and development and demonstration of large-scale wind power and large-capacity pumped-energy storage joint operation optimization technology; broke key technologies for intelligent operation and flexible control of AC-DC interconnected large-scale power grids containing large-scale new energy sources, and demonstrated applications in China Southern Power Grid. The scale covers 8 AC and 9 DC trans-provincial power transmission channels.
Developed a wireless charging device for electric vehicles, established a layered optimization and operation system for electric power supply for electric vehicles, conducted research and demonstration of intermittent new energy consumption and optimization technologies for active distribution networks, and developed key equipment for intelligent distribution network optimization and dispatching. And systems, carried out research and development and demonstration of new measurement, communication and protection technologies for smart distribution networks; carried out R&D and demonstration of key technologies for efficient and reliable operation of micro-grid; conducted power grid demonstrations for joint operation of wind, fire, and high-energy-carrying enterprises. Application: Completed the intelligent integration of large-scale iron and steel enterprises' power grids with intelligent power technologies, completed demonstration applications in Shougang Jingtang, launched comprehensive integration and demonstration of oilfield group intelligent distribution networks, and built a smart distribution network demonstration project in CNOOC Kenli 3-2 oilfield group. .
The achievements achieved in this project have played a role in improving new energy absorption capacity, supporting the scaled operation of electric vehicles, and improving the reliability of microgrids. At the same time, they have provided intelligent deployment of electricity to large industrial enterprises and intelligent distribution networks for offshore drilling platforms. Bigger support.
The expert group unanimously believed that the project completed the research content and major assessment indicators stipulated in the project notice and agreed that the project passed the acceptance.
