Zhang Boming Zhang Boming, born in Chongqing City in 1948, is a wellknown international expert on electric power system operation and control. He obtained his M. Sc. from Harbin Institute of Technology in 1982 and his Ph.D. from Tsinghua University in 1985, respectively, all in Electrical Engineering. After his graduation, he joined Tsinghua University as an academic staff where he is now a full professor. He is a Fellow of the IEEE and a member of the Steering Committees of the CIGRE China National Committee and International Workshop on Electrical Power Control Centers, respectively. Professor Zhang has been working in the area of power system dispatch automation for over 30 years. He pioneered, developed and implemented the first advanced application software of Energy Management System (EMS) in China in early 1990s, and he was subsequently awarded the State Prize for Scientific & Technological Progress for his outstanding contributions to EMS development in 1992. During the past 20 years, Professor Zhang proposed and developed a dozen practical algorithms and implementation technologies on EMS and three of the notable examples are: Recursive Measurement Error Estimation Identification (RMEEI) method for bad data identification in 1991; Integrated GraphModelDatabase (IGMD) technology for network modeling in 1995; and N－1＋1 Security Analysis technology for district power networks in 1998. Many of his proposals have been extensively used and have dominated technological development in the EMS area in China as well as in many other parts of the world. Professor Zhang started the widearea Automatic Voltage Control (AVC) research in 1995. In the past 15 years, Professor Zhang and his research team overcomes many technical bottleneck problems in AVC, such as temporal coordination for three level AVC, online adaptive networkzonedivision for coordinated secondary voltage control, spatial coordination for AVC among multiple control centers, and optimal AVC control with mixed discrete and continual control variables, etc. The AVC system with threedimensional coordination, developed by his research team, has been successfully applied to more than 16 provincial power grids in China and lately it is adopted by PJM interconnected power grid of USA in 2009. This is the first AVC system operating in USA. Professor Zhang is the holder of 19 China Invention Patents. He was awarded the State Prize for Technology Invention for his contributions to technical development in threedimensional coordination of new generation of EMS in 2008. Professor Zhang is a man of great attainments in power system analysis theory. He has authored and coauthored 455 technical papers and 4 books. His book, Advanced Electric Power Network Analysis, was first published in Chinese in 1996. It has been widely used by graduate students and engineers in the electric power system profession all over China. The English version of this book has been published recently. Professor Zhang has been lecturing to undergraduate and graduate students at Tsinghua University on power system analysis for more than 20 years. He supervised many graduate students in the past 20 years including 22 PhD graduates and 10 postdoctorates. Many of his graduated students are now holding key positions in the power system profession in China and over the world. Professor Zhang’s contribution to the power system field is worldrecognized. He was elected as an IEEE Fellow in 2010 for his contributions to algorithm development for energy management system in power system control centers.
