Demand Response Load Shedding: Thermostat Cycling & Cold-Load Pickup

Interactive 3D demand-response simulator: an aggregator cycles hundreds of residential air-conditioners on and off during a DR event, watch the aggregate grid load drop against its baseline, then see the cold-load-pickup rebound spike when the event ends -- and how staggering the restart tames it.

A grid of hundreds of houses, each running its own dead-band thermostat model, lets you watch a real demand-response event unfold from the inside. Enroll a share of the fleet in a direct-load-control program, set how hard the aggregator curtails their air conditioners, and watch the aggregate grid load fall away from its uncontrolled baseline in real time. Switch between rotating (staggered) and synchronized curtailment to see the trade-off utilities actually manage: staggering spreads the shed load evenly and keeps the recovery gentle, while synchronized cycling shows the sharp cold-load-pickup rebound that hits the grid the moment a DR event ends.

⚙ Under the hood

Enroll a fleet of hundreds of residential air conditioners in a direct-load-control demand-response program, watch the aggregate grid load fall below its baseline as an aggregator duty-cycles their thermostats, then compare a staggered restart against a synchronized one to see the cold-load-pickup rebound.
