The laboratory has long been committed to the basic theoretical research and key technological breakthroughs in power generation, transmission, transformation, and system operation, making foundational and leading contributions. It has been deeply involved in the technical research and development of all major power generation, transmission, and transformation projects in China. It pioneered the theory of nonlinear control in power systems and developed grid dispatch, control, and protection technologies covering domestic power grids. It also developed China's first power system dynamic simulation platform and the first set of thermal power simulation systems, pioneering in this field. Additionally, it pioneered the organic external insulation pollution flashover prevention technology, with organic insulators accounting for 70% of China's ultra/high-voltage power grids. The laboratory has led in winning three National Science and Technology Progress First Prizes, 14 Second Prizes, and has been involved in 23 National Awards (including 3 special awards) in recent years. Over the past five years, the laboratory has received 15 national-level awards, including 2 Special Prizes for Scientific and Technological Progress, 3 First Prizes for Scientific and Technological Progress, 3 Second Prizes for Technical Invention, and 7 Second Prizes for Scientific and Technological Progress.
