摘要：Power system scheduling with renewable power integration aims to determine the scheduled power of conventional power plants and renewable power plants. This paper proposes a day-ahead power system scheduling method considering period-to-period ramp-capability constraints with renewable power uncertainty. The renewable uncertainty cost is considered based on the overestimation and underestimation penalty cost and further converted to be a linear model. The period-to-period ramp-capability constraints with renewable power uncertainty are incorporated into the proposed day-ahead scheduling model, which ensures that any period-to-period power trajectory within upper and lower envelops are restricted by the ramping up and down limits. Finally, numerical studies in the IEEE 118-bus system are presented to demonstrate the merits of the proposed method.
