Senior power-engineer playbook for contingency violations. Use whenever N-1 or N-2 studies reveal voltage or thermal problems, binding contingencies, or post-outage islanding — including escalations from a tool skill's contingency run. Triggers on "N-1 violation", "worst contingency", "preventive vs corrective action", or "do we need a RAS". Moves from ranking contingencies to identifying preventive and corrective actions that cover a family of outages.

Senior power-engineer playbook for power-flow convergence failures. Use whenever a base case or post-change case diverges, oscillates, or fails to solve in PSS/E, PSLF, PowerWorld, pandapower, PyPSA, surge, or OpenDSS. Triggers on "power flow diverged", "case won't solve", "did not converge", "blown-up voltages", or "max iterations reached". Every tool skill stops on a non-convergent base case — this playbook is what to do next, separating data errors from numerical fragility from genuine physical infeasibility.

Senior power-engineer playbook for distribution DER integration limits. Use whenever rooftop or utility-scale PV, storage, or other DERs push a feeder into voltage rise, reverse power flow, thermal limits, or protection desensitization — or when the question is how much more DER a feeder can host. Triggers on "hosting capacity", "PV on this feeder", "voltage rise from solar", "reverse power flow", or "DER interconnection on distribution". Pairs naturally with OpenDSS and pandapower feeder studies.

Senior power-engineer playbook for dynamic stability problems. Use whenever eigenvalue or time-domain studies show poor damping, transient angle instability, weak voltage recovery, or sustained oscillations in tools such as ANDES or PSS/E — including escalations from a tool skill's dynamic run. Triggers on "low damping", "unstable after the fault", "tune the PSS", or "voltage recovery too slow". Gives an ordered fix sequence across dispatch, controls, protection, and special schemes.

Senior power-engineer playbook for frequency-performance problems. Use whenever studies or operations show low system inertia, poor frequency nadir, high RoCoF, weak primary frequency response, UFLS encroachment, or reserve shortfall after loss of the largest unit or HVDC import. Triggers on "frequency nadir", "RoCoF too high", "inertia too low", "UFLS risk", "primary frequency response", or "loss of largest unit". Distinct from dynamic-stability-mitigation, which handles damping and angle stability rather than frequency containment.
