Estimating air conditioning load control effectiveness using an engineering model

The authors describe a method to evaluate the potential effectiveness of a direct air conditioner load control program. Developed through a comprehensive load research program coupled with engineering insights into the energy use of residential air conditioning systems, this method results in an algorithm that has been utilized to evaluate the potential for load control on three utility systems in the western US. Variables to be monitored through the load research are presented and a procedure is developed that will allow the system planner to determine if such a program will be cost-effective and successful compared to a program developed through a more traditional pilot or demonstration approach. How the same methodology can be used is outlined for determining a procedure for the dispatcher to properly initiate and terminate a load control program without causing significant problems with customer air conditioning cooling loads and comfort.<>
