Thermostatically controlled loads

Definition

Thermostatically controlled loads refer to electrical devices, such as heating and cooling systems, that operate based on a preset temperature. These loads can be adjusted or controlled remotely, allowing them to participate in demand response programs that help balance electricity supply and demand in smart grids. By shifting or reducing their energy usage during peak demand periods, these devices play a crucial role in optimizing overall energy efficiency and grid reliability.
