With the advent of the smart grid era, the electrical grid is becoming a complex network in which different technologies coexist to bring benefits to both customers and operators. This paper presents a methodology for analyzing Key Performance Indicators (KPIs), providing knowledge about the performance and efficiency of energy systems, focusing on the demand side. In the first stage of the methodology, the baseline KPIs are calculated. In the second stage, all KPIs are updated to be compared with the baseline ones. In fact, due to the dynamic nature of players in a smart grid, this methodology plays a crucial role in the performance assessment. Moreover, the proper definition and selection of KPIs is usually a challenging task since KPIs can be applied to evaluate diverse areas within a smart grid. Such areas include building energy efficiency, home communications, and smart metering deployment, just to mention a few. In the proposed methodology, the information obtained from a KPI can be driven to distinct aspects such as efficiency, environment, reliability, power quality, safety, security, or cost reduction. Through a case study from a real implementation of an energy system, we show how to assess energy consumption efficiency, thus improving energy management.

能源关键绩效指标分析的方法

随着智能电网时代的到来，电网正在成为一个复杂的网络，其中各种技术共存，为客户和运营商带来利益。本文提出了一种用于分析关键绩效指标（KPI）的方法，提供了有关能源系统的性能和效率的知识，重点放在需求方面。在该方法的第一阶段，将计算基准KPI。在第二阶段，所有KPI都会更新以与基准KPI进行比较。实际上，由于智能电网中参与者的动态性质，这种方法在绩效评估中起着至关重要的作用。此外，正确定义和选择KPI通常是一项艰巨的任务，因为KPI可以用于评估智能电网中的各个区域。这些领域包括建筑节能，家庭通信和智能电表部署，仅举几例。在提出的方法中，可以将从KPI获得的信息驱动到不同的方面，例如效率，环境，可靠性，电源质量，安全性，安全性或成本降低。通过实际实施能源系统的案例研究，我们展示了如何评估能源消耗效率，从而改善能源管理。
