Design of a Home Energy Management System Based on Cloud Service

With the increasingly serious energy and environmental problems, the proportion of new energy in total energy consumption increased continuously, the application of new energy in the home micro-grid can effectively alleviate the energy crisis, then the monitoring of energy in the home microgrid is becoming more critical. Based on the traditional home micro-grid, a home energy control system was designed which covers the home micro-grid architecture, the network communication control, and the human-computer interaction. The supervisory control and data acquisition (SCADA) was designed to monitor the working status of each component in the home micro-grid through various communication methods such as WIFI and RS485. For the current power load which has no communication ability, a smart socket based on WIFI was designed for the monitoring of home appliances and power supply equipment. The working data of the underlying device is upload to the cloud server built by the intelligent gateway and the human-computer interaction interface, the database storage system for running data, and the human-machine interface adopts the WeChat public number which can avoid many developments, then effectively reducing the cost of operations for user learning. The cloud-service-based home energy management system can effectively promote energy utilization and make home energy management more intelligent.
