The Flow of Information
summary
Claims the power grid is a distributed control system with a global 60 Hz signal and simple AGC running ~every 4 seconds using integral (PI) loops; day-ahead forecasts show ~5% errors and California faces multi-gigawatt ramps from the duck curve. Batteries cost billions, lose ~10% round trip and Escondido’s ~30 MWh (Tesla later built 129 MWh in Australia) is expensive; experiments at University of Florida show HVAC and water heaters can provide virtual energy storage (100 buildings ≈1 MW, ~120k water heaters ≈30 MW and ~128 MWh) and track Reg D signals with no user impact.
