#4 Interview With Ashwin Khambadkone

Lalit and Abhijit talk to Prof. Ashwin Khambadkone who is currently a Professor at the National University of Singapore, and has rich experience in academia as well as industry.

  1. Guest Profile: Prof. Ashwin Khambadkone:
  1. Change in Air Pollution levels due to Coronavirus (Article from Science Daily)
  2. Renewable Energy Sources are non-dispachable
  3. Traditional power system:
    • Generation follows variation in demand for Power Balance
    • RES are both variable and uncertain
    • Data Analytics, Data Mining, Big Data etc have a lot of potential in providing some prediction and addressing uncertainity.
  4. Non-Technology based solutions:
  5. Problems need to be solved beyond purely from technology-basis
  6. Need to keep in mind the humans interacting with the system and the behavioural aspects of these interactions.
  7. More choice is not always necessary:
    • e.g. stock market investing is “automated”
    • Not just an electronic solution – a system solution
  8. Evolution of technology solutions:
    • Old systems relied on “muscle” power and had heavy user interaction
    • Evolved into energy self sufficiency
    • Evolving into control self sufficiency
  9. Old way of doing engineering is changing – need to be aware of and understand the entire system
  10. “Making engineering more interesting”
  11. How should students of today prepare themselves for the challenges of complex-system thinking in modern jobs?
  12. First year curriculum re-design:
  13. Phasor representations
    • Harmonics cannot be shown in conventional phasor diagrams
    • Ask questions and connect the dots: link it to your own experience
    • Systems thinking: Universal input voltage range
  14. How to ask questions the smart way. Prioritize your questions – we are in an information rich world
  15. How to find answers
    • IEEE Spectrum, Electronics Magazines (Bodo, etc) How stuff works.com
    • Websites of manufacturers
    • Youtube teardown sites
    • AmpHour Forum
    • Electronics Stackexchange
    • Electronics Reddit, r/AskEngineering
  16. Get a layman’s understanding: “You do not really understand something unless you can explain it to your grandmother.” this quote has been attributed to a number of people, not sure of actual origin
  17. Industry projects:
    • The most important thing is to understand what the customer needs
    • Its not always about just taking the best algorithm
    • You need to consider things which no standard textbook will teach, e.g. current limit as a function of thermal loading of devices
    • The system you develop should not require a PhD to operate!
    • Run the system for an entire day!
  18. Problem definition is key!
  19. Multidisciplinary Approach
  20. The chase of a “Novel Idea”
  21. Closing remarks:
    • Identify your priorities first!
