Study on Model of Interruptible Load to Participate in Reserve Market

The interruptible loads(ILs) which participates in the reserve market can ease the reserve shortage during emergency. In this paper a model which is based on the optimal power flow (OPF) for ILs to participate in the reserve spot market is introduced, the ISO could use this model to determine the real-time selection of the interruptible load bidders considering system operating reserve and impact of ILs´s location. It is shown that the interruptible load market helps to reduce the system demand and raise the level of system reserve during the peak hours and in cases of contingencies. The IEEE 9-Bus system, considerably modified to represent different customer characteristics, has been used for the study.
