Station Power Budget: Load-Shedding Controller

A space station's life support runs entirely on solar power stored in batteries, and every subsystem — CO₂ scrubbing, thermal control, oxygen electrolysis, water recycling, lighting, comms, science — competes for the same limited watts every time the station passes into Earth's shadow. This simulator models a degrading solar array and a battery bank feeding a priority-ranked stack of loads in real time: as state of charge falls through a low threshold, a load-shedding controller drops the least essential subsystems first to protect life-critical ones, then restores them in reverse order once the battery recovers above a higher threshold — the same undervoltage load-shedding logic real spacecraft power buses use. Tune array degradation, orbital period, eclipse fraction and battery capacity, or trigger a sudden micrometeorite strike, and watch which subsystems survive.
