DESIGN AND EXPERIMENTAL IMPLEMENTATION OF HOME AUTOMATION SYSTEM CONSIDERING SMART GRID AND ENERGY MANAGEMENT REQUIREMENTS

Abstract

This work presents the design and laboratory implementation of a Home Automation System (HAS), that considers the requirements of Smart Grid (SG) for monitoring the electrical variables, sending Demand Responses (DR) and the requirements of Home Energy Management System (HEMS) to schedule the home appliances operation, improve energy consumption without sacrificing the user needs as allowing the user to choose the appliances priorities, accept / deny the DR and control the energy consumption using the user inputs. A laboratory set-up has been assembled using industrial units as follows: power metering (PM) to monitor voltage, current, energy consumption comes from the appliances, human machine interface (HMI) to monitor the electrical variables and the bill calculated by the control unit, control the settings by the user, control unit as a PLC to control the data sent and received from the HMI and utility center (UC), home area network (HAN), data transmission/ receive (MODEM) with a simulated utility center and a simulated electrical loads. A group of HMI displays has been configured to offer the user the ability of: monitoring of status, variables, energy bill and presetting of priorities and parameters. Results of a daily performance are presented to indicate the affectivity of the implemented HAS.
