Use this skill for transmission power-system studies — AC/DC power flow, DC-OPF / AC-OPF / SCOPF, N-1 / N-2 contingency analysis, PTDF / LODF / OTDF sensitivities, NERC and AC Available Transfer Capability (ATC), SCED economic dispatch, and SCUC unit commitment. Also use for building or editing a transmission network (add / remove / scale buses, lines, transformers, generators, loads, storage). Use whenever the user references an IEEE benchmark case (case9, case14, case30, case57, case118, case300, market30) or IEEE 14-/30-/57-/118-/300-bus network, or asks to load a MATPOWER .m, PSS/E RAW, XIIDM, or CIM/CGMES file and run a steady-state study. Trigger on phrases like "power flow", "run OPF", "contingency analysis", "PTDF", "ATC", "economic dispatch", "unit commitment", "build a network", or "scale load by X%" — even if the user does not mention Surge by name. Not for transient-stability dynamics (route to ANDES) or harmonic / unbalanced distribution feeders (route to OpenDSS).
Progressive-disclosure workflow for ANDES studies. Use when the user asks to run ANDES through PowerMCP for power flow, small-signal stability, or time-domain simulation, and when the agent should expose base-case steps before advanced dynamic analysis.
Senior power-engineer playbook for contingency violations. Use when N-1 or N-2 studies reveal voltage or thermal problems and the agent needs to move from ranking contingencies to identifying preventive or corrective actions.
Senior power-engineer playbook for dynamic stability problems. Use when eigenvalue or time-domain studies show poor damping, transient angle instability, weak voltage recovery, or related dynamic-performance issues in tools such as ANDES or PSSE.
Progressive-disclosure workflow for Egret optimization studies. Use when the user asks to run DC OPF, AC OPF, or unit commitment through PowerMCP, and when the agent should solve the simplest credible optimization before escalating to full commitment studies.
Progressive-disclosure workflow for LTSpice or PyLTSpice studies. Use when the user asks to create a netlist, run a circuit simulation, inspect traces, or debug LTSpice behavior through PowerMCP, and when the agent should expose session creation and simulation before plotting or GUI steps.
Progressive-disclosure workflow for OpenDSS feeder studies. Use when the user asks to compile a DSS model, solve a distribution circuit, inspect feeder voltages or power, run load multipliers, or perform daily or harmonic studies through PowerMCP, with base-case checks before advanced scenarios.
Senior power-engineer playbook for planning and operations optimization problems. Use when Egret or PyPSA studies are infeasible, reserve-deficient, congested, too expensive, or heavily curtailed, and the agent needs corrective actions rather than only reporting optimization output.
