We are glad to invite you to a seminar by Dr. Sudipta Ghosh, titled “Advanced Approaches to Renewable Energy Integrated Power System Modeling and Energy Management”
Modern power grid is more complex and shows unforeseen dynamics. Rapid control decisions have to be taken on the basis of multiple contingency evaluations using limited computational resources. Such analyses are time consuming, exceeds computational limits and difficult to accomplish in faster time frames. Model order reduction (MOR) is one such tool in control engineering which can simplify system formulations while retaining phenomena of interest. This work shows 1) a new approach for coherency identification that captures dynamic behavior of the power grid, 2) a new methodology for scalable power system coherency grouping based on mathematical (BT & Krylov subspace) MOR of larger power grid including online PSS tuning methodology. Further the work explains reduced order modeling of wind turbines & wind farms. The work also describes 1) a new wind farm control framework for inertial and primary frequency response for a high wind integrated power system, 2) an energy function based optimal control strategy for output stabilization of integrated DFIG-flywheel energy storage architecture to avoid voltage and power fluctuations, 3) a new dynamic reactive power estimation based coordinated control of grid integrated DFIGs to improve network stability. Further a real-time model reduction of large power grid into an equivalent network while preserving low and high frequency behavior of the original system will be presented.
Sudipta Ghosh received his Ph.D. degree from Indian Institute of Technology, Delhi in 2013 in Power Systems. From 2013-2014, he worked as Assistant Professor at IIT, Dhanbad. In 2014 he came to USA as a Research fellow at the University of North Carolina (UNCC), at Charlotte. He was a lead researcher for the Hybrid real time simulator based advance modeling of the Southern California Edison grid. He also worked as a lead researcher for the NSF funded project on power system on new methods of optimal control designs integrating renewable energy systems research. Next year, he was appointed as Graduate Associate Faculty at UNCC. In this context, he was assisting PhD and Master’s students and working on a NSF project. Currently he is working as an Associate Professor at Adamas University. He has 7 years teaching/research experience and 3 years industrial experiences. He is a member of the IEEE and IEEE PES. His publication record consists of nine journals and seven conference papers (total 277 google scholar citations). He received the National Scholarship in 1995 and POSCO power system Award from Power Grid in 2014.
