Dispatching of Active Power Reserve for Higher Reliability of Restructured Power Systems

In power systems that are restructured on the basis of system reliability or the costs, various methods can be employed for allocating the spinning reserve to various generating units. This paper firstly describes two methods for allocation of reserve power: (1) a cost-based method; (2) a reliability-based method. Secondly, presents a combined method that simultaneously considers both reliability and the costs. After reviewing the results of each method, a new method will be presented that can be applied in the restructured power system. To demonstrate the results of various methods, this research has used the IEEE network model RTS (Reliability Test System) with 24 Bus bars.
