🏔️ Pumped-Storage Station: Reservoirs, Turbine, Pump and Battery (2D cross-section)

2D cross-section of an alpine pumped-storage station with an upper and a lower reservoir, a turbine, a pump, a small battery and a settlement. Set the turbine gate, pump command, head, losses, demand and rainfall, and track reservoir levels, generation, pumping and grid balance over hours. Uses the same physics file as the 3D page, with four in-page numerical checks.
