Influence of Time-of-Use Strategy on Optimal Load Reserve Capacity in Market Environment
摘要
Abstract
The introduction of time-of-use （TOU） strategy will change the load quantity value per hour. In addition, it also influences on unserved energy cost and compensation cost of interruptible load. Consequently, the system reliability and reserve purchasing situation will be changed. In allusion to the influence of TOU strategy on unserved energy cost and compensation cost of interruptible load, taking the minimal social cost for purchasing reserve capacity in each time interval, a dynamic reserve purchasing model, in which the influence of TOU price is taken into account, is established by probability method, and the reserve purchasing situations in varius time intercals are researched by calculation example. Research results show that the social cost in valley load period increases to some extent than the implementation of TOU strategy, and that in peak load period decreases. Meanwhile, due to the influence of TOU price, the purchase quantity of interruptible load drops to the lowest in the valley load period and rises to the highest in peak load period, thus the established model can well reflect the influence of TOU price on reserve purchasing situation.关键词
