Direct load control considering interrupted energy assessment rate in restructured power systems

A direct load control (DLC) scheme of air conditioning loads (ACL), which considers the interrupted energy assessment rate (IEAR) of nodes where ACL are connected, is proposed in this paper for restructured power systems. The IEAR is utilized to determine the compensation for the discomfort of the ACL customers due to the service interruption caused by the DLC of ACL. Dynamic programming is used to determine the optimal DLC scheme of ACL under the minimum total system operating cost. The IEEE reliability test system is simulated to illustrate the proposed DLC technique of ACL.
