Open-source grid defense learning
Learn defense scheme logic through visible power flow.
A practical simulator for understanding load flow, overload shedding, islanding, generator runback, blackstart restoration, and explainable trip-matrix decisions. Built for engineers, students, and operators who want to see the logic instead of only reading it.
Learning paths with practical grid behavior.
Each page explains one concept in plain engineering language and links back to the interactive simulator.
Power Flow
See MW direction, import/export behavior, energized paths, and overload corridors.
02Load Flow
Understand source-load balance and why topology changes alter operating limits.
03Adaptive Defense Scheme
Learn why trip decisions should follow current network condition, not a fixed list only.
04Islanding
Explore grid separation, local balance, interconnector limits, and island-mode actions.
05Blackstart
Follow staged restoration concepts after blackout using visible sources and loads.
06Microgrid
Connect defense scheme logic to local generation, islanding, and priority loads.
Why it helps
Most power-system concepts are easier to understand when the network state is visible. The simulator shows energized paths, animated flow, overload indication, and the logic behind selected corrective actions.
Use it to learn
- How line outages and bus splits change MW flow direction.
- Why OLS, OGS, islanding, and blackstart need different decisions.
- How a trip matrix can be explained to engineers and operators.
