  7. Abstract:
  8. Considering the high penetration of renewable energy resources in modern power systems, independent system operator faces considerable uncertainty and variability in the system under supervision. In this regard, determining and providing the appropriate amount of operational reserve is critical to overcoming uncertainty and variability to have reliable system performance. In practice, power system operators prefer to use deterministic approaches to schedule operational reserve. Such approaches have benefits in simplicity and fast calculations. Nevertheless, increasing share of renewable resources causes a considerable error in these approaches. Therefore, many researchers have proposed probabilistic approaches to replace approximate deterministic criteria in recent years. Although probabilistic methods provide accurate solutions, they are time-consuming and overly complicated, hence not applicable for large power systems. In addition to inconsistency in reserve scheduling methods, some weaknesses exist within the current reserve-providing regulation. The thesis proposes a novel method for determining reserve by disintegrating a large power system into several Virtual power plants (VPPs). The proposed method is a fast alternative for deterministic methods in determining reserve. In addition, the application of this method is a beginning of a paradigm shift that alleviates mentioned weaknesses related to determining and provision of reserve margins. Such a paradigm shift will be based on assigning reserve responsibility to dependent VPPs, and vice versa regulate an appropriate framework in which they can make profits in good reserve provision performance
