Builds an optimisation from a Victoria five‑minute snapshot and shows exactly what is modelled and why it matters: a two-generator toy grid with demand forced equal to generation, dispatch solved every five minutes and prices that can go negative, how infeasible peaks become an unserved-energy variable with a $40,000 penalty, and how capacity becomes a decision via a buildable gas variable. Uses Python data shaping with pandas and an optimisation solver, adds dump variables and renewable availability limits, and shows what the solver actually returns.
