摘要
提出一种电热水器用水时段的划分方法。首先,以用水时段控制电热水器的方式,构建出对应控制方法的能耗模型。其次,为尽量满足用户需求,保障必要的用水并尽量降低非用水时段的保温能耗,构建一个以概率阈值为自变量的用户耗电量目标函数。再次,使用粒子群优化算法求解目标函数得出满足用户需求的概率阈值。最后,使用最佳概率阈值反向推导得出用户的用水时段和非用水时段的划分区间。基于改进后的用水时段划分结果设计出了新的热水器保温算法,该算法的实际应用可在不影响用户用水体验的基础上节省大量电能。
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 consumption objective function with probability threshold as an independent variable was developed to meet the users’needs,ensure necessary water use and minimize the thermal insulation energy consumption in the non-water-use period.Next,a particle swarm optimization algorithm was used to solve the objective function and then to derive a probability threshold that satisfies the user’s demands.Finally,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 practical application,through this algorithm,a lot of power can be saved without affecting normal water use.
