A National Workshop on Real-Time Digital Simulation for Power Engineering Applications

IEEE Student Branch Chapter IIT Mandi in collaboration with IEEE IAS SB Chapter of IIT Mandi organized a national workshop on “Real-Time Digital Simulation for Power Engineering Applications”, 13-16 June 2019 at IIT Mandi.

This workshop was partially sponsored by IEEE IAS and Science and Engineering Research Board (SERB), India. The workshop’s objective was to enhance the knowledge of the participants in the area of the “Real-Time Digital Simulation for Power Engineering Applications”. With the theme of “Real-Time Digital Simulation for Power Engineering Applications,” this event was providing an environment for research scholars, faculty members, and industry personnel to know, grow, develop, experience and exchange their ideas to fortifying the technological developments. Modern power systems are progressing towards cutting-edge technology which demands the whole new ideas in operations, power management/utilization and this makes the real-time simulators inevitable. So flexible, scalable, fast and practical ground-based real-time digital system is the key requirement of the present electrical power systems. Here at IIT Mandi, we usually carry out our complex and critical research works fluently with such a state-of-the-art real-time digital simulator system. The drive of this workshop is to provide acquaintance to the participants in the direction of real-time digital simulation used for power engineering and industrial applications. Our motive is to deliver the latest and best-in-class procedural training to participants. This program was including lecture sessions, discussions on research issues by the participants, poster presentation and most importantly an intensive hands-on training on state-of-the-art digital simulators that are available in the power engineering laboratory of IIT Mandi.

A unique, national-level opportunity that delved into the high-level, strategic issues relating to applications of the Power System Engineering, Power Electronics, Electrical Machines, and Renewable Energy systems. The workshop provided a platform for an in-depth discussion on the various challenges and their possible remedies which benefited participants from academic/ R&D institutions and engineers. The 04 days workshop was included demonstration experiments/ training on Real-Time Digital Simulator (RTDS) and OPAL-RT and research solutions for the Power Engineering applications.

The workshop was attended by the students of IIT Mandi and other institutes. The workshop on real-time computing is to bring together researchers working on real-time systems (undergraduate and graduate students and Ph.D. students, faculty members, postdocs, etc.). The workshop provides a relaxed forum to present and discuss new ideas, to explore new research directions, and to review current trends in the real-time systems area. It is based on both short presentations and hands-on experience sessions to encourage stimulating discussions.

The scope of the workshop includes (but is not limited to) the following areas:

Real-time system design and analysis: task and message scheduling, modeling, verification, worst-case execution time estimation, distributed systems, fault tolerance, quality of service.

Infrastructure and hardware for real-time systems: Advance electrical machine drives, power electronics converters, power generation, transmission, and distribution system.

Software technologies for real-time systems: compilers, programming languages, and component-based technologies.

Real-time applications: Robotics and automation, power generation system, electrical drives and etc.

Speaking about the impact of the workshop, Dr. Bharat S. Rajpurohit, coordinator of the workshop and Associate Professor, School of Computing and Electrical Engineering, IIT Mandi, said, that a large number of participant registrations shows the importance and significance of learning RTDS and Opal RT tool.  Since the topic of the workshop was related to their academic and curriculum growth, participants from different streams have shown their interest in the workshop. There were more than 65 candidates registration in total out of which approximately 35 were from other neighboring state institutes. He also greeted the resource persons from RTDS and Opal RT who took efforts and time confirming their attendance to the workshop for giving hands-on training to the attendees.

Highlighting the unique aspects of this workshop, Prof. S. N. Singh, Fellow, IEEE, Vice-chancellor, MMMUT, Gorakhpur, India, delivered a lecture on “Estimation of Grid Harmonics in the Presence of Renewable Energy Sources”. Prof. Singh briefed major concerns of power system design & operation like; Quality, Reliability, Security, and Economy. He covered major issues and challenges in Power System Applications.  He also discusses on the role of Power Electronics Applications in Power Systems and why Harmonics are matter of concerns. Prof. Singh has covered stat-of-art signal processing and intelligent techniques for estimation of non-stationary harmonics. He has shared several experimental results to support the analytical foundations. The participants raised several questions related to current scenario of power system stability and issues about harmonics.

Prof. S. N Singh obtained his M.Tech and PhD in Electrical Engineering from Indian Institute of Technology Kanpur, in 1989 and 1995 respectively. Presently, he is a Vice-Chancellor at Madan Mohan MalviyaUniversity ofTechnology, Gorakhpur and leave from Professor (HAG),Department of Electrical Engineering, Indian Institute of TechnologyKanpur, India. Before joining IIT Kanpur as an Associate Professor, Dr.Singh worked with UP State Electricity Board as an Assistant Engineerfrom 1988 to 1996, with Roorkee University (now IIT Roorkee) asAssistant Professor from 1996 to 2000 and with Asian Institute of Technology, Bangkok, Thailand as Assistant Professor from 2001 to 2002.

The chief guest of the workshop was Prof.  Ramesh Oruganti.
