Commercial demand side management using a programmable logic controller

摘要

Many methods of shedding load during peak hours of operation have been utilized for efficient use of generation during peak periods. These methods, however, are usually nondynamic, meaning that power for commercial, industrial, or residential appliances are simply turned on or off as needed. As load management customers increase, a variety of load shedding criteria emerges. Some commercial customers in the load management program demand dynamic or routine based power control to ensure the safety of their large equipment such as refrigeration units. The authors propose one such method to accommodate this need.
