Impact of Smart Metering on Home Energy Management: A Comparison to State-of-the-Art Power Sensors

Abstract:
The transformation of the energy system, particularly through the integration of prosumers, necessitates advancements in home energy management systems to enhance energy efficiency and sustainability. This paper explores the role of Intelligent Metering Systems within this transformation, highlighted by the German government's smart meter rollout initiative, ensuring the availability of Smart Meter Gateways in prosumer households. These systems provide precise measurements critical for optimizing energy use through home energy management systems. However, the integration of Intelligent Metering Systems faces challenges, such as latencies resulting from encryption, which could affect the measurements of residential residual load at the grid connection point. To address these concerns, a comparative analysis was conducted in a laboratory setup, evaluating an Energy Meter, and an iMSys, and a standard electronic metering system equipped with an optical probe. The findings necessitated further comparative analysis to assess how sensor latencies impact the effectiveness of energy management.
