Adaptive load management: a system for incorporating customer electrical demand information for demand and supply side energy management

Abstract

A method for determining an amount of electricity to purchase includes determining electrical power consumption characteristics of an electrical load at an end user of the electricity. A preference of the end user for an output of the electrical load is ascertained. The output varies with a rate of electrical power consumption by the load. A mathematical model is created of an amount of electrical power to be consumed by the load as a function of time and of monetary cost of the electricity. The model is dependent upon the electrical power consumption characteristics of the electrical load and the preference of the end user for an output of the electrical load. An amount of electricity is purchased based on the mathematical model of an amount of electrical power to be consumed by the load, and based on the monetary cost of the electricity.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to methods for managing the use of electricity, and, more particularly, to methods for managing the use of electricity by consumers wherein the methods may be at least partially based on values the consumers place on the electricity usage.[0003]2. Description of the Related Art[0004]The price and consumption of energy throughout the world has been increasing dramatically over recent years and is expected to continue along this trend in the years to come. For example, according to the U.S. Department of Energy Annual Energy Outlook, total residential energy consumption is expected to increase by approximately twenty percent from 2007 to 2030 despite efficiency improvements. This is attributed to a number of factors including a projected twenty-four percent increase in the number of households and an approximately seven percent increase in the share of electricity attributed to “other” applia...

Benefits of technology

[0029]An advantage of the present invention is that it provides efficient allocation of electricity resources based on consumer preferences and the consumers' willingness to pay for different levels of electricity during different time periods.

Problems solved by technology

Until very recently, there has been an active skepticism concerning benefits from retail competition.

These concepts have never materialized for a variety of reasons, perhaps the key reason being a lack of adequate incentives to encourage users to respond.

However, hardly any frameworks have attempted to systematically integrate large-scale responses from, and preferences of, the individual building users in residential and commercial buildings.
