【摘要】：电能替代是解决能源短缺,缓解大气变化问题,构建绿色能源消费模式的创新理念和重要措施,全电智能家居是电能替代的主要形式。然而全电智能家居等设备的推广改变着居民用户的用电方式和传统住宅小区的高峰负荷需求,并将随着电能替代的推广愈演愈烈。因此,在电能替代的背景下,如何通过先进的信息和通信技术,深入电网和用电环节,为必需的基础设施提供能源管理和家电优化控制等服务,是本文将要讨论的问题。本文针对以上问题开展了电能替代下全电智能家居的家电优化控制策略研究。首先,本文为了解决用电优化中样本数据难以获取的问题,首先提出了一种基于Copula理论的家庭用电场景模拟方法,利用小样本数据构造出满足家电设备开启时间和使用时间相关关系的Copula函数,生成体量更大的数据集合作为分析样本,为研究用电优化策略提供数据支撑。其次,针对单体用户,本文采用了经济学中的效用理论模拟用户使用电器的满意程度,进而指导电力用户能够制定符合自身偏好的用电优化策略。最后,针对小区内用户群用电负荷,可能存在的设备集中开启形成小区局部用电高峰问题,本文提出了一种基于启动时间延迟的家庭负荷管理优化策略,能够在负荷高峰时刻下对各个负荷运行周期施加一个最优的相位延迟,达到负荷均衡化的目标。
[Abstract]:Electric energy substitution is an innovative idea and an important measure to solve the energy shortage, alleviate the problem of atmosphere change, and construct the green energy consumption mode. However, the popularization of all electricity smart home and other devices has changed the power consumption mode of the residents and the peak load demand of the traditional residential area, and will become more and more intense with the promotion of electric power substitution. Therefore, under the background of electric power substitution, how to provide energy management and household appliance optimization control services for the necessary infrastructure through advanced information and communication technology, deep into the power grid and power supply links, is the problem to be discussed in this paper. In order to solve the above problems, this paper studies the optimal control strategy of all-electric smart home appliances. First of all, in order to solve the problem that sample data is difficult to obtain in the optimization of power consumption, a method of household electricity scene simulation based on Copula theory is proposed in this paper. The Copula function is constructed by using small sample data to satisfy the relationship between the opening time and the usage time of household appliances, and the larger volume data set is generated as the analysis sample, which provides the data support for the study of the power consumption optimization strategy. Secondly, the utility theory in economics is used to simulate the satisfaction of the users in the use of electrical appliances, and then to guide the power users to formulate the optimal power use strategy in accordance with their own preferences. Finally, in view of the problem that the power load of the user group in the district may be concentrated to form the peak of local power consumption in the district, this paper proposes an optimized strategy of household load management based on the start-up time delay. The optimal phase delay can be applied to each load cycle at peak load time to achieve the goal of load equalization.
