Architecture of Web Services Interface for A Home Energy Management System

This paper proposes a web-based architecture to enable information retrieval and appliance management for a Home Energy Management (HEM) system. With the proposed architecture, homeowners can monitor their basic energy usage information, and can perform necessary appliance management based on their pre-defined load priority, preferences, and comfort settings. The proposed architecture is designed based on the Standard Energy Usage Information (PAP10), which ensures interoperability among smart grid equipment. It is also designed with comprehensive security measures. It is expected that the proposed architecture can serve as a reference model for custom hardware designs and implementation of a real time, lightweight and reliable embedded web server for HEM applications in the smart grid environment.
