Phasors, three-phase power and transformers
about 3 weeks (about 12 hrs/week)
Read the 6.061 text chapters on power, three-phase systems and transformers. Then solve 6.061 problem sets 1, 2 and 4. Self-check: MIT 6.061 problem sets 1–11 with solutions. Free tools only.
Proof required
Link the public repo with 6.061 problem sets 1, 2 and 4 written up (a typeset PDF, LaTeX source or notebook), and show the self-check: which answers matched and how you fixed the ones that did not.
What gets checked
- Real, reactive and apparent power are kept apart.
- Per-unit values are converted correctly.
- Answers match the published solutions, and misses are reworked.
Common mistakes
- Answers copied from a solution with no working.
- Missing units, or a sign or factor-of-2π slip left unexplained.
Powstik Guide
A public write-up of 6.061 problem sets 1, 2 and 4, with the self-check shown.
Steps
- Study the linked course material.
- Solve the problems on your own first.
- Check them against the self-check and rework the misses.
- Typeset the write-up (LaTeX or a notebook) in a public repo.
- Ask someone who knows the subject to check it.

What a verifier looks for
- Real, reactive and apparent power are kept apart.
- Per-unit values are converted correctly.
- Answers match the published solutions, and misses are reworked.
- Is the engineering right, not just the final number?

Transmission lines, load flow and faults
about 3 weeks (about 12 hrs/week)
Read the 6.061 text chapters on lines and load flow; watch the NPTEL Power System Analysis lectures on load flow and faults. Then solve 6.061 problem sets 3 and 5, and the load-flow problems in sets 6–7. Self-check: MIT 6.061 problem sets 1–11 with solutions. Free tools only.
Proof required
Link the public repo with 6.061 problem sets 3 and 5, and the load-flow problems in sets 6–7 written up (a typeset PDF, LaTeX source or notebook), and show the self-check: which answers matched and how you fixed the ones that did not.
What gets checked
- Line models fit the line length.
- Load-flow iterations are shown to converge.
- Answers match the published solutions, and misses are reworked.
Common mistakes
- Answers copied from a solution with no working.
- Missing units, or a sign or factor-of-2π slip left unexplained.

Electromechanics and machines
about 3 weeks (about 12 hrs/week)
Read the 6.061 text chapters on magnetic circuits, forces and machines. Then solve 6.061 problem sets 8–10, and the force problems in sets 6–7. Self-check: MIT 6.061 problem sets 1–11 with solutions. Free tools only.
Proof required
Link the public repo with 6.061 problem sets 8–10, and the force problems in sets 6–7 written up (a typeset PDF, LaTeX source or notebook), and show the self-check: which answers matched and how you fixed the ones that did not.
What gets checked
- Energy and co-energy methods give the same force.
- Machine equivalent circuits are solved with units.
- Answers match the published solutions, and misses are reworked.
Common mistakes
- Answers copied from a solution with no working.
- Missing units, or a sign or factor-of-2π slip left unexplained.

Run a load-flow study of a small grid
about 3 weeks (about 12 hrs/week)
Make a load-flow and fault study of a standard test grid (the IEEE 9-bus or 14-bus case) in pandapower. Predict one line's real-power flow by hand with a DC load-flow approximation, then run the AC load flow. Add a solar plant (a static generator) and a line outage, and name every voltage or loading limit that breaks. Add the short-circuit data the case lacks, and compute one bus's three-phase fault current by hand and in pandapower. Put every hand-vs-pandapower number in one table.
Proof required
Link the public repo with the code or design files, the one command that reruns it, and the predicted-vs-simulated table, and a README that says how to rerun it and what limits the result.
What gets checked
- The notebook runs from the repo and reproduces every number.
- Hand predictions (DC line flow, fault current) are within 10% of pandapower, or the gap is explained.
- Every broken limit is named, with a fix that the rerun shows working.
Common mistakes
- A result that nobody else can rerun from the repo.
- A table with no explanation of the gaps.
Powstik Guide
A load-flow and fault study of a standard test grid (the IEEE 9-bus or 14-bus case) in pandapower, in a public repo.
Steps
- Write down what you expect before you start.
- Predict one line's real-power flow by hand with a DC load-flow approximation, then run the AC load flow. Add a solar plant (a static generator) and a line outage, and name every voltage or loading limit that breaks. Add the short-circuit data the case lacks, and compute one bus's three-phase fault current by hand and in pandapower. Put every hand-vs-pandapower number in one table.
- Fill the predicted-vs-measured table.
- Explain every gap with a cause someone can check.
- Write the README and ask someone who knows the subject to rerun it.

What gets sent back
- It does not run from the repo.
- No predicted-vs-measured table.

- Rerun it from the repo: does it run, and do the numbers match the table?
