    Abstract

    We have analyzed and designed a Home Energy Management System. This


    system provides real-time energy and budgeting information to help
    residential consumers optimize their electricity use. It reduces financial
    costs through a digital user-interface that intelligently directs how energy is
    consumed. Consumers can use our software to dynamically interact with the
    electrical appliances of their buildings. The user gains four new abilities
    through our system: (i) computational management of how much money is
    being spent in real-time; (ii) investigation of the energy efficiency of
    individual appliances; (iii) wireless manipulation of electrical appliances and
    systems; and (iv) automation of personal and professional consumption
    patterns. There are five essential processes of our system: (i) generate user
    interface, (ii) transform and analyze user instructions, (iii) write automation
    programs, (iv) manipulate electrical appliance/system, and (v) transform and
    transmit energy consumption data. A subset of examples from our system’s
    many attractive applications include: turning off kitchen lights in real-time
    from a mobile phone; heating bedrooms by 2° C every morning at 9:00 am;
    ceasing all power transmission to electrical appliances from 9:30 am through
    4:30 pm on work days; and turning off all user-defined “discretionary”
    appliances if current energy price exceeds maximum acceptable price.

    Requirements

    Our system must include a software application that interacts with the
    electrical appliances of residential buildings. This software should provide
    energy customers with four main functions:
    i. Ability to see how much money is being spent in real-time
    ii. Ability to assess the energy efficiency of individual appliances
    iii. Ability to remotely turn on and off appliances
    iv. Ability to customize and automate consumption patterns

    The implementation of our Home Energy Management System will provide four
    major improvements to the existing energy consumption system:

    Old Energy System New Energy System


    Customers discover their energy costs Customers can know their costs, by the
    once per month by snail-mail. minute, electronically.
    Customers are blind to what appliances Customers can access detailed visual
    use and waste the most energy. displays of energy use.
    Customers must be near an appliance to Customers can control their appliances
    turn it on and off. wirelessly from anywhere.
    Customers must manually interact with Customers can automate when their
    their electrical appliances. appliances are used through programs.

    There are four groups of people that must cooperate to make this new system
    function effectively:
    i. Residential Customers
    ii. Electric Power Utility Firms
    iii. Retail Manufacturers, Engineers, and Architects
    iv. System Integrators
    We are the system integrators.

    The main inputs are electricity, real-time pricing rate, powering on and off
    instructions, and automating preferences. The main outputs are dynamic
    powering on and off of products, historical and real-time consumption data,
    and a regular purchase invoice.

    Concluding Remarks

    Analyzing and designing the Home Energy Management System was insightful
    and exciting for all of the Smart Gators. By applying concepts and
    techniques taught in class to our system, we were able to better understand
    and manipulate ISM 4113 lessons. We especially enhanced our process
    modeling skills. Further, we gained a significant understanding of an
    emerging industry, known as smart grid technology, and the opportunity to
    get a head-start on establishing a career as an industry leader. We will all
    also be capable of intelligently pursuing financial investment opportunities
    related to these systems. While our system certainly presented many
    technical challenges in being accurately conceptualized and modeled, we did
    not face any show-stopping obstacles; thus, we are very proud in our belief
    that our Home Energy Management System is of the best quality possible,
    given our innate constraints of limited time and limited experience. To
    conclude, we are satisfied with the nature and outcomes of this project, and
    appreciative of the instructor’s guidance in this regard.
