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.

description

Dynamic stability mitigation

Start only after the disturbance, monitored channels, and failing metric are explicit.

Preferred action order

Confirm the models and event setup are credible: machine data, control models, fault location, clearing time, and initial dispatch.
Reduce the stressed transfer or dispatch pattern that drives the instability.
Improve controls: AVR, PSS, governor, FACTS, or dynamic VAR support.
Improve protection or switching performance if clearing time is the binding issue.
Consider RAS, fast valving, braking resistors, or controlled load shedding only with explicit trigger logic.

Working rules

Use eigenvalues to screen and time-domain simulation to confirm.
Separate angle instability, oscillatory instability, and voltage recovery problems; they do not share the same fix order.
Re-check the steady-state dispatch after major control or topology changes.

Deliver

The failing mode or scenario.
The mitigation sequence that should be tried.
The first credible fix and the remaining validation needed.

convergence-failure-mitigation

Power-Agent/PowerSkills

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.

der-hosting-capacity-mitigation

Power-Agent/PowerSkills

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.

frequency-response-mitigation

Power-Agent/PowerSkills

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.

interconnection-impact-mitigation

Power-Agent/PowerSkills

Senior power-engineer playbook for screening and mitigating the grid impact of a new generator, storage, or large-load interconnection. Use whenever the question is whether X MW can connect at a point of interconnection and what upgrades it needs. Triggers on "interconnection study", "system impact study", "POI", "can we connect this plant at bus Y", "short-circuit ratio", or "weak grid". Walks from steady-state screens through weak-grid and reactive checks to the binding constraint and its mitigation set.

short-circuit-mitigation

Power-Agent/PowerSkills

Senior power-engineer playbook for excessive fault current and breaker over-duty. Use whenever a short-circuit study shows fault duty above interrupting ratings, or a new interconnection raises fault levels near equipment limits. Triggers on "fault duty", "breaker over-duty", "short-circuit current too high", "interrupting rating exceeded", or "fault MVA at this bus". Gives an ordered sequence from study verification through operational fixes to equipment upgrades.

andes

Power-Agent/PowerSkills

Progressive-disclosure workflow for ANDES dynamic studies. Use whenever the user wants to run ANDES through PowerMCP for power flow, small-signal / eigenvalue analysis, or time-domain simulation — even when they just say "check the damping", "is this stable", "run a fault", or "look at the oscillation modes". Exposes a solved base case before eigenvalue screening and time-domain runs. Reach for this instead of answering ANDES dynamics questions unaided.
