摘　　要：通过建筑能源管理系统提供成本效益,提出了一种优化调度和竞标策略的建筑能源管理系统(BEMS)模型。通过在上层最小化电能成本确定次日电能数量竞标,考虑了预期不确定性的成本,而一些较低层次的子问题确保了建筑负载和分布式能源资源的最佳运行,以保留舒适性,最小化消费者的不便和住宅储能单元的降级。首先对电动汽车的可用性、SOC水平以及日常通勤的能量消耗进行了预测;其次模拟研究了热泵运行计划,热泵能源需求夏季降低了15%~22%,冬季降低了10%~12%;最后利用建筑热质量和灵活的温度范围,实现了热泵能源需求的最小化,储能设备的降解减少了2~3倍。This study proposes a Building Energy Management Systems(BEMS)model that offers cost-effective optimization scheduling and bidding strategies.The model minimizes electricity cost at the upper layer to determine the bid quantity for the next day,considering cost with expected uncertainty,while lower-level sub-problems ensure the optimal operation of building loads and distributed energy resources to preserve comfort,minimize consumer inconvenience,and mitigate degradation of residential energy storage units.Firstly,predictions were made regarding the availability of electric vehicles(EVs),State of Charge(SOC)levels,and energy consumption for daily commuting.Secondly,simulations were conducted to study the operation plan of heat pumps,resulting in a reduction of 15%to 22%in summer and 10%to 12%in winter in heat pump energy demand.Subsequently,by utilizing building thermal mass and flexible temperature ranges,the study achieved minimization of heat pump energy demand and reduced degradation of energy storage devices by 2-3 times.
