Abstract

The main benefits of implementing interruptible load management for power suppliers are from the impacts of the level of demand for electricity on spot prices. In terms of CVaR as the measuring index for market trading risk, a model of load curtailing strategies for power suppliers considering the co-utilization of the interruptible load with low price (ILL) and the interruptible load with high compensation price (ILH) is proposed. The load curtailing strategies under different levels of demand for electricity are analyzed. The results show that the curtailing strategies for power suppliers are more progressive taking the impacts of interruptible load on spot prices into account, and that the optimal curtailing strategy involving in curtailing the ILL up to the upper limit before curtailing any of the ILH. Due to the economic complementarity of ILL and ILH contracts, the co-utilization of both contracts will receive more benefits than of any single one.
