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.

Power flow Load shedding Islanding Blackstart Microgrid

Learning paths with practical grid behavior.

Each page explains one concept in plain engineering language and links back to the interactive simulator.

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.
