Smart Grid

A smart grid is an electric power system that employs modern power electronics, advanced instrumentation, secure communication, and information technologies so that it is robust against disturbances with the least likelihood of blackouts and is efficient in energy transfer between sources and loads at the lowest cost to consumers. The grid should also provide quality power to various loads and accommodate wind, solar and other alternative power generation and storage options. To achieve these objectives, research is needed to develop innovative technologies and tools in the areas of transmission, distribution, energy storage, power electronics, cyber security and instrumentation. The Smart Grid Team will conduct research on the following problems:

  • Optimum and Stable Operation: Develop and test algorithms for accurate power system state estimation and control using PMU (phasor measurement unit) measurements for optimum operation; Design real-time stability assessment techniques to be used as load management and load shedding; Power marketing;
  • Efficient Integration of Sources and Loads: Design advanced power electronic circuits and techniques for integration of renewable energy sources to power systems and improve power quality;
  • Resilient and Secure Communication: Design wireless communication systems to facilitate two way communication between consumers and control centers and to implement real time power market;
  • Ageing and Lifetime issues: Age determination based on condition rather than years in service; Estimation of leftover life of critical components (e.g. transformer) in the grid under stressed conditions to permit economical and efficient routing of power
  • Accurate Instrumentation: Design of advanced PMUs, smart meters and other instruments;
  • Protection against disturbances and threats: Improve protection using digital instrumentation, communication and switch gear; and
  • Information Technology Applications:

Grand Challenges

  • Make the grid self-healing from power disturbance events.
  • Enable active participation by consumers in demand response.
  • Operate the grid resiliently against physical and cyber attacks.
  • Provide quality power for 21st century needs.
  • Accommodate all generation and storage options in the grid.
  • Optimize assets and operate the grid efficiently.

  • Since cyber security is an important aspect of smart grid research we are happy to report that one of our students, Vitaly Ford representing TTU, has been placed 1st among approximately 150 players in National Cyber League Capture the Flag competition in Intermediate Advanced group. He has been ranked 6th among all groups and players (approximately 800 nationwide including most advanced ones). This is the 1st time a TTU student has participated in any security competition. Vitaly is an officer of the TTU CyberEagles club and a graduate research assistant in Smart Grid Security group, Center for Energy Systems Research. Congratulations Vitaly!
  • On September 24 2013, Rabie Belkacemi, Adeniyi Babalola, Ali Fliachi and Funso Ariyo presented their paper, "Restoration of Smart Grid Distribution System using Two-Way Communication Capability" at the North American Power Symposium conference. The conference, which took place at Kansas State University/Manhattan, covers both technical and social advances in its 45-year history. The technology outlined in the paper was specifically mentioned in one of the conference's keynote addresses. Link!

  • A presentation targetting students for smart grid research on an in-house laboratory power grid can be found HERE!
  • Satish Mahajan won the TTU Kinslow Award for a smart grid sensor paper employing GPS to provide real time measurements of transmission line sag. When a transmission line carries a lot of power the heat generated actually causes the power line to stretch and sag. Real time measurements of sag provide feedback about transmission lines which are over taxed.
  • Former CESR student, Tapan K. Manna, Ph.D., P.E. is presenting a seminar Thursday November 15, 2012 at 3:00 p.m. in Brown Hall 208 entitled Field Testing of Oil Filled Transformers. This correlates well to CESR smart grid research in that Dr. Mahajan has been developing smart sensors to provide effective age of transformers.
  • Former CESR student, Tapan K. Manna, Ph.D., P.E. is presenting a seminar Friday November 16, 2012 at 3:00 p.m. in Brown Hall 208 entitled HVDC Growth in US Transmission Networks. It is of note that under a recent DOE project, power line sag instrumentation developed at TTU was tested at the ORNL HVDC field test site.
  • Robert Craven recently attended the TREEDC DIY solar installation workshop on Oct 18th 2012 at the University of Tennessee Conference Center. The workshop stressed that typical solar installations require roofing expertise, solar expertise, and electrical expertise all merged and that a Do It Yourselfer should get help in the areas that they are not proficient in themselves. The presentations were augmented by an excellent collection of articles provided as handouts.
