Smart home energy management by Demand Response controller design

Abstract

This paper includes an HEM algorithm for managing household power-intensive appliances. The highlight of the proposed HEM algorithm is its ability to control selected appliances and keep the total household power consumption below a certain limit, while considering customer preferences and allowing the customer more flexibility to operate their appliances. Advanced Metering Infrastructure (AMI) coupled with Demand Response enables to relieve the stress on the Power System at the times of peak load while simultaneously shifting it to non-peak periods which enables us to achieve a higher load factor and consequently, cheaper cost of production of electricity. This paper presents a prototype of a Smart Controller working on the principle of Demand Response for managing high power consumption household appliances. The controller manages household loads according to their preset priority and guarantees the total house-hold power consumption below certain levels. A hardware model has been developed on an Arduino board to showcase the applicability of the proposed algorithm in performing DR at a lumped load level.
