Simulated demand response of a residential energy management system

A residential energy management system (REMS) is an amalgamation of hardware and software that performs monitoring, planning, and control functions of the energy utilization within a residence. The REMS system is designed to provide desirable demand response (DR) to price or system condition utility signals. This paper presents simulated results of a proposed REMS system to provide automated DR. The simulation test bed is structured as a discrete event simulation of a single household for a full day. Four scenarios with varying levels of automation are compared. The application of the proposed REMS results in reduced average power and energy use during the DR service time. These services are achieved by delaying the use of controllable electric appliances (clothes dryer, clothes washer, dishwasher, and plug-in electric vehicle) prior to and during the DR service time. Finally, simple payback time computations for the considered scenarios are presented.
