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

ABSTRACT: This paper presents a very effective method for direct load control (DLC) dispatch with the objective of minimizing system operational costs. In the paper, the coordination between DLC dispatch and unit commitment is discussed, and the significant potential benefit accrued from using DLC capacity as a part of system spinning reserve is illustrated. This paper also presents an extension of the proposed method to include consideration of capital cost saving.IEEE Transactions on Power Systems 12/1995; · 2.92 Impact Factor
