论文摘要

负载点是电力系统中最重要的部分之一。由于需求端引入的新负载表格和程序,负载服务实体(LSE)不再处理结块负载,而是具有更动态,理性和价格弹性负载。负载曲线的高时空间和行为变异性几乎使公用事业和系统运营商不可能以所需的准确性期望需求曲线。全年负载组成和消费百分比和模式的声音颗粒性对于避免能源损失,设计需求侧管理计划以及确保对电力率进行适当调整至关重要。在本文中,系统操作员可以最初了解客户的消费模式和家庭负载结构,然后提出了一个简单的模型。自上而下的方法与详细的自下而上的方法结合在一起,以提取负载组成和百分比。模型中包括与家庭统计数据(例如使用设备的使用时间(TOU),每个房屋的设备单位数量以及家庭中进行的活动的真实和本地负载概况,都包含在模型中。该论文的主要结果表明,在基于季节性的情况下,住宅需求的负载成分以及此类组成的百分比。

Load points are one of the most vital parts of power systems. Due to the new load forms and programs introduced in the demand side, the load-serving entities (LSEs) no longer deal with lump loads, but rather with more dynamic, rational and price elastic loads. The high inter-temporal and behavioral variability of the load profile makes it almost impossible for utilities and system operators to expect the demand curve with the needed accuracy. A sound granularity of the load compositions and consumption percentages and patterns throughout the year is essential for avoiding energy losses, designing demand-side management programs, and ensuring proper adjustments of electricity rates. In this paper, a simplistic model that can be followed by system operators to initially understand the customers' consumption pattern and the household load structure is proposed. A top-down approach is combined and matched with a detailed bottom-up one, to extract load compositions and percentages. Real and local load profiles integrated with household statistical data such as device time of use (ToU), number of device units per house, and activities exercised in households are all included in the model. The main results of the paper show the load composition in residential demand and the percentage of such composition under seasonal-based scenarios.
