DESIGN AND IMPLEMENTATION OF A HOME ENERGY MANAGEMENT SYSTEM WITH DEMAND RESPONSE CAPABILITIES USING IOT TECHNIQUE

Abstract

The increasing demand for electricity and the emergence of smart grids have presented new opportunities for a home energy management system (HEMS) that can reduce energy usage. The HEMS incorporates a demand response (DR) tool that shifts and curtails demand to improve home energy consumption. This thesis presents the implementation of a proposed HEMS system using microcontroller. The system includes: - Microcontroller based actuators (smart plugs) that measure and can switch loads, - HEMS main controller that implements a load management algorithm that can incorporate demand response actions. - Wifi Network communication based on MQTT between controller and actuators. - User Interface to monitor the HEMS and to enable the user to customize the controller operation by assigning load priorities and required comfort level.
