PURPOSE
    Define a formal AI-readable ontology for Power Systems, including
    generation, transmission, distribution, substations, buses, lines,
    cables, transformers, loads, generators, voltage, current, frequency,
    active power, reactive power, apparent power, power factor, load flow,
    faults, stability, protection, grounding, control, reliability,
    monitoring, operation, provenance, uncertainty, confidence and
    recursive power-system reasoning.

CORE_DEFINITION
    Power Systems are interconnected electrical networks that generate,
    transmit, distribute, control and supply electrical energy while
    maintaining acceptable voltage, frequency, power quality, stability,
    protection, reliability and operational performance.

    Critical Distinction
        Power-system reasoning must preserve network topology and switching
        state while distinguishing active, reactive and apparent power,
        power factor from efficiency, voltage magnitude from angle and
        installed capacity from available operating margin. Frequency,
        units, base values and measurement provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Power Systems are interconnected networks for generating, transmitting,
    distributing and supplying electrical energy. Reliable power-system
    reasoning preserves topology, bus identities, switching states,
    generator and load data, transformer settings, voltage magnitude and
    angle, frequency, active and reactive power, protection and measurement
    provenance while distinguishing installed capacity from operating
    margin and power factor from electrical efficiency.
