A method of dividing water use periods according to users'behavioral habits of using electric water heaters
A method of dividing use water periods of electric water heater was proposed in the paper.First,an energy consumption model was constructed according to the electric water heater control mode in terms of the water use periods.Then,a user power con-sumption objective function with probability threshold as an independent variable was developed to meet the users'needs,ensure nec-essary water use and minimize the thermal insulation energy consumption in the non-water-use period.Next,a particle swarm optimiza-tion algorithm was used to solve the objective function and then to derive a probability threshold that satisfies the user's demands.Fi-nally,aided with the optimal probability threshold,the intervals of water and non-water periods for the users were derived.Based on the improved division results of water use periods,a new insulation algorithm of the electric water heater has been designed.In practi-cal application,through this algorithm,a lot of power can be saved without affecting normal water use.
