Course details

This course is designed mainly for postgraduate (PG) students who are studying Power Electronics, Power Systems, and Control Systems. It is also useful for anyone who wants to understand how modern electrical grids are evolving with renewable energy.The course starts by explaining the basic ideas of microgrids in a very clear and simple manner. Students will learn what a microgrid is, why it is needed, and how it is different from the traditional centralized power grid. The course also explains the main components of a microgrid, such as distributed generation sources (solar, wind, batteries), power electronic converters, energy storage systems, and loads.Different types of microgrids—AC microgrids, DC microgrids, and hybrid microgrids—are discussed, along with their advantages and real-world applications. Special emphasis is given to DC microgrids, including their structure, operating principles, and why they are becoming popular in renewable energy systems, electric vehicles, data centers, and smart buildings.
Overall, this course provides a strong foundation for students and researchers who want to work in the fast-growing and emerging field of renewable energy and smart power systems, especially those planning to do research or higher studies in microgrid technologies.

Questions and Answers

Q: You're on site for SAT and searching "dc microgrid pre-commissioning insulation resistance test sequence 750V acceptance". The DC bus IR just measured 0.82 MΩ to PE at 750 Vdc. What's the correct next action before energizing converters?

A: 1 MΩ at rated DC voltage is the hard boundary that bites here. Below that, you can't argue temperature or cable length during SAT. Sectioning isolates whether the leakage sits in a feeder or converter input, and it avoids masking by IMD thresholds that sit lower and act after energization.

Q: Operations calls after you googled "dc microgrid droop control circulating current parallel converters". Two 50 kW DC/DC units in parallel show 6 A circulating current at no load, bus voltage hunts ±2%. What's the most likely root cause?

A: 2% bus hunting with zero external load points to control law, not power hardware. A few amps of circulating current at no load maps cleanly to unequal droop slopes; sensor saturation would pin readings, and polarity reversal would rail the loop immediately.

Q: During HAZOP you search "dc microgrid isolation monitoring device limitation what it does not protect". The IMD fails low. What hazard is NOT mitigated by the IMD even when healthy?

A: 30–100 kΩ alarm thresholds deal with insulation state, not ampacity. An IMD can't see copper heating from overload; that's squarely in the domain of overcurrent protection and thermal models.

Q: Your lead sends you "dc microgrid loop check sequence dc voltage transducer plc scaling" before commissioning today. What's the correct order to verify a DC voltage transducer loop tied to the PLC?

A: 10 V or 4–20 mA injection before full voltage is the guardrail. Cold checks catch polarity and shorts without exposing the PLC AI to 750 Vdc mistakes that turn into latent damage.
