Load Scheduling of Thermostatical House-Hold Appliances Against Abrupt Changes in Smart Grid

The security of power grid is of great importance for the development of modern society, and the balance of supply and demand is critical to ensure the reliability and security. Smart appliances, which are important parts of smart grid and can help balance the supply and demand. The load scheduling can decide whether the appliances should be running or resting at some point, and the load scheduling of thermostatical house-hold appliances can help securing the smart grid when abrupt changes occur. However, the load scheduling should be user-friendly, which have been ignored in many researches. In this paper, user-friendliness indicators of a load scheduling are given. We propose a load scheduling of thermostatical house-hold appliances against abrupt changes in smart grid, and each appliance is treated as an agent. Each agent chooses to run or rest based on the state of the smart grid and its own state. The simulation results show that the load scheduling we propose is user-friendly and can keep the smart grid in a safe state.
