- Electrification of devices like heat pumps, induction cooking, and EVs helps reduce carbon emissions when powered by renewable energy.
- Households typically use 10-25 kWh daily, with peak power draw up to 5 kW. EV charging can significantly increase peak demand.
- Grid congestion occurs when synchronized device usage or solar panel feedback exceeds grid capacity, risking failure.
- Smart grids enable demand-side management by adjusting consumption based on energy production, optimizing usage.
- Time shiftable devices (e.g., washing machines) can be scheduled to minimize peak power draw or energy costs.
- Optimizing multiple devices is complex due to exponential growth in possible start time combinations.
- Profile steering offers a practical approach to find near-optimal schedules for multiple devices.
- Current pricing models may incentivize clustering of energy use, requiring new incentive structures for better grid management.
