Professor Hongbin Sun research achievements listed as 'Top-10 Science and Technology Progresses of Chinese Universities' in 2016
 

In the late Dec. 2016, the Science & Technology Commission of the Chinese Ministry of Education announced the annual award of “Top-10 Science and Technology Progresses of Chinese Universities”. The research on “the key technology and application of autonomous-synergic automatic reactive power and voltage control system for complex power grid“, led by Prof. Hongbin Sun from Tsinghua University, was listed as one of them.

Prof. Sun serves as a Vice Chair of WFEO Committee on Energy.

Hongbin Sun, born in 1969, admitted to Tsinghua University in 1987. He obtained the bachelor and Phd degree of electrical engineering from Tsinghua University in 1992 and 1996 respectively. Now, he is a full professor of the Department of Electrical Engineering in Tsinghua University, deputy director of the Research Center of Environmental Science and New Energy in Tsinghua-Berkeley Shenzhen Institute (TBSI), the director of the TBSI smart grid and renewable energy laboratory. He is the National Prominent Educator, Changjiang Scholars of the Ministry of Education, Outstanding Youth Fund holder, Fellow of the British Institute of engineering and Technology (IET).

Voltage level is the core metrics of power system operation. However, the reliable and effective control of voltage is a worldwide difficult problem, especially in large-scale and complex power networks. Voltage problems are believed to be among the main causes which have led to several major power outages in the past years. In addition, it also impedes the large-scale integration of renewable energy in China. With more than 20 years’ hard work, Professor Sun’s team has resolved series of technical problems of voltage control in complex power grid.

Their advanced voltage control technology can now serve most of the application scenarios, from single-control-center systems to multi-control-center systems, from conventional power systems to those with large-scale of integrated renewable energies, and from domestic cases to foreign cases (i.e. PJM in the U.S., Malaysia State Grid, etc.). Prof. Sun’s team has obtained 57 patents of invention in China, and 3 in the U.S., and successfully developed a voltage control application system for complex power systems with independent intellectual property rights.

The system has controlled 56% of the conventional generating units (fossil-fired and hydropower) and 37% of the wind/solar generation facilities in China, and is in charge of the voltage control of all the ultra-high voltage transmission lines and their neighbor zone grids. Their product has opened a new era of exported advanced power grid control technology from China to the U.S.. Significant benefits on improvements of security and economy of power system operation and renewable energy integration have been obtained.

In 2016, the appraisal committee led by six academicians in China announced that the project is a “major original research achievement”, a “worldwide leading contribution”, and “a milestone in this research field”. Prof. Anjan Bose, who is an academician of the U.S. National Academy of Engineering, said that Prof. Sun’s achievement “has put China far ahead than the rest of the world in better control of the grid voltage thus lowering the probability of grid failures”.
