ABSTRACT: A Home Energy Management (HEM) system plays a crucial role in realizing residential Demand
Response programs in the smart grid environment. It provides a homeowner the ability to automatically perform smart
load controls based on utility signals, customers preference and load priority. The HEMs communication time delay to
perform load control is analyzed, along with its residual energy consumption. The main aim is to design how each load
performs when being controlled by the HEM unit and measure electrical measurements for the different loads. Demand
response (DR) is defined as changes in electricity use by demand-side resources from their normal consumption
patterns in response to changes in the price of electricity. HEM system comprises an HEM unit that provides
monitoring and control functionalities for a homeowner, and load controllers that gather electrical consumption data
from selected appliances and perform local control based on command signals from the HEM system. A gateway, such
as a smart meter, can be used to provide an interface between a utility and the data base for the electrical consumption
is maintained.
