Integrated demand response for energy utilization

Abstract

A method for managing power consumption within a facility includes receiving a request to reduce a total level of power consumption within the facility by a predetermined measure (S23). A plurality of operating parameters indicative of how much power is being consumed by each of a plurality of facility systems is received (S21). A corresponding cost associated with a marginal power reduction is determined for each of the plurality of facility systems using the received plurality of operating parameters (S24). A power allocation to the facility system of the plurality of facility systems that is determined to have a lowest marginal cost of power reduction is incrementally reduced (S25). The steps of determining a corresponding cost and incrementally reducing power are repeated until the total level of power consumption within the facility has been reduced by the predetermined measure.

Description

[0001] Cross references to related applications [0002] This application is based on the provisional application serial number No. 61 / 359,897 filed on June 30, 2011, and the entire content of which is incorporated herein by reference. Technical field [0003] The present disclosure relates to energy utilization, and more specifically to integrated demand response for energy utilization. Background technique [0004] Large facilities (such as skyscrapers and industrial factories) tend to consume large amounts of energy from various sources. Energy sources include grid electricity, liquid and gaseous fossil fuels, and renewable sources such as solar and wind energy. Each of the various different energy sources has different advantages, disadvantages, and prices. The relative price of energy sources can fluctuate based on the time of day, current usage, or various other market factors. [0005] Power consumption in large facilities can be the result of climate control systems, lighti...

[0008] Inefficient use of energy has both economic and environmental consequences

In addition, peak demand for electricity overloads the grid and forces power suppliers to build additional power plants, which may be used only a few times of the year

For example, in the US, greater than 10% of electricity infrastructure costs are spent to meet peak demand that occurs less than 1% of the time
