Load Analysis and Energy Management for Residential System Using Smart Meter

In this paper, the design of load analysis and residential energy management system using a smart meter is is discussed. The AC and DC voltage and current sensors, light and heat sensors, room occupancy counter design is discussed. The sensors are connected to Arduino Mega board. A 3.2-inch TFT display is integrated with Arduino board to display the results. The Arduino Mega board is programmed to save and display the voltage, current, power factor and energy measurement for each load, automatically control the room light based on number of occupants, automatically or manually turn off the high energy consuming loads during peak power demand time, display the sensor information and energy saving tips for saving energy. The novelty of this design is its user friendly display controls with submenu options to set the maximum usage levels, review the previous usage levels and access to energy saving tips. To test the design, two DC and two AC loads were used. The measured load voltages and current are displayed and discussed. The further development of this design can be done by adding low cost energy saving IoT and communication device to monitor, turn on and turn off the loads remotely.
