Cooper Power Systems Unveils New Technology for More Effective Demand Response
New algorithm provides control of over-sized air conditioners that use energy efficient technology

Cooper Power Systems, a division of Cooper Industries, Ltd. (NYSE: CBE), today announced completion of its new MagCycle algorithm, designed for demand response applications. The new algorithm is the next generation of TrueCycle technology utilized by Cooper Power Systems devices, and is designed to work with over-sized air conditioners that are designed for increased energy efficiency. MagCycle will also be incorporated into the Company’s offering of load control receivers.

“Some of the techniques air conditioner manufacturers use to make their equipment more energy efficient makes it impossible to judge compressor over-sizing from the control circuit,” stated Roger Rognli, Program Manager at Cooper Power Systems and co-developer of the MagCycle algorithm. “MagCycle incorporates actual demand to optimize the curtailment of highly efficient variable speed and multiple stage units to provide the necessary load reduction utilities are demanding.”

Typically in demand response applications, the utility calls a reduction event when it experiences its peak. The goal of the demand response event is to provide power where it is needed most in order to avoid engaging expensive and inefficient peaking plants. With more efficient units now being sold by air conditioning manufacturers, algorithms incorporated into traditional demand response devices will become less effective on over-sized air conditioning units.

MagCycle ensures utilities still have the ability to reduce the demand from over-sized air conditioning units to meet the demands of their grid. This advanced technology addresses the challenges with over-sized compressors which results in a 20% to 30% improvement in program efficiency.

“Cooper Power Systems is constantly working on developing new technology the utility industry requires,” stated Cooper Power Systems group president, Mike Stoessl. “This new algorithm is another example of Cooper’s ability to evolve with the changing needs of utilities, and provide technology to meet new obstacles and challenges.”
