基于需求响应的家庭能效管理优化调度

Household energy efficiency management and optimal dispatch base on demand response

随着经济的快速发展,家庭用户的用电量逐年上升,在全社会用电量中的比重也逐步提升,对家庭各类用电设备进行优化调控,可减少用户的用电费用开支。提出了一种家庭能效管理调控策略,将家庭用电负荷分为可调节、可转移、可中断和可削减4种类型,分别建立数学模型,同时计及使用寿命建立了家用蓄电池的功率模型和电量模型,在基于分时电价并计及分布式屋顶光伏发电的情况下对需求响应资源进行优化控制。最后通过算例仿真分析,验证了有效的调控策略能够减少家庭用户的用电费用开支,同时能够促进分布式屋顶光伏的就地消纳。

With the rapid pace of economic development,electric power consumption of home users is increasing year by year,which also accounts for a big part in total social power consumption.Hence,it is significant to conduct researches on optimal control of different types of household loads,so that electricity expense of home users can be reduced.In this paper,a control strategy of household energy efficiency management system is proposed,and mathematical models of four different types of household loads are established,including adjustable loads,transferrable loads,interruptible loads and reducible loads.Meanwhile,charging and discharging power model and capacity model of battery energy storage are formulated respectively,considering its life cycle.And optimal control of demand response resources are carried out based on time?of?use price and distributed roof photovoltaic generation.Finally,a numerical example is studied,which demonstrates that the electricity expense of a home user can be reduced remarkably through the proposed optimal control strategy,and the utilization of the distributed PV generation can be improved.
