Abstract

With the accelerated development of economy, the proportion of household electricity power consumption in total power consumption is getting larger and larger. So it is necessary to have a research on the optimal control of different types of household loads so as to reduce power consumers' cost as well as to improve household energy efficiency. In this paper, an optimal control strategy of household energy efficiency management is presented, focusing on an electricity user who owns multiple types of household loads. In this control strategy, different types of household loads, the rooftop photovoltaic generation equipment, and as well as the household energy storage devices are all taken into account and modeled respectively. The coordinated optimal control of all these loads is discussed considering the time-of-use price. A numerical example demonstrates that the total power cost of a family can be reduced remarkably by carrying out the optimal control strategy proposed, and also, the utilization efficiency of the rooftop PV power generation equipment can be improved.
家庭能源效率管理和优化与能源存储
随着经济的加速发展,家庭用电占总用电量的比重越来越大。因此,有必要对不同类型家庭负荷的最优控制进行研究,以降低电力消费者的成本,提高家庭的能源效率。本文针对某用户拥有多种家庭负荷的情况,提出了一种家庭能效管理的最优控制策略。在该控制策略中,分别考虑了不同类型的家庭负荷、屋顶光伏发电设备和家庭储能设备,并对其进行了建模。在考虑分时电价的情况下,讨论了各负荷的协调最优控制问题。数值算例表明,采用所提出的最优控制策略可以显著降低家庭总电力成本,提高屋顶光伏发电设备的利用效率。
