Operating reserve of thermal unit systems with interruptible loads

This paper presents the determination of the 10-minute operating reserve (OR) of the unit commitment (UC) function based on the probabilistic approach. An initial deterministic reserve criterion is used to test the system performance of a 6-thermal unit system. This work takes into account the demand side participation for reserve contributions and studies the system economics and reliability of a power system which incorporates interruptible loads (ILs). It illustrates the feasibility of IL incorporation at different load levels thus enables ISO to better manage reserve allocation.
