  7. Abstract:
  8. Power system operators are facing with imperative challenges to integrate high penetration of renewable power plants. The main challenge is required investment cost for accommodating the grid with uncertainties of renewable resources. In addition, intermittency and fluctuations of renewable resources are another challenges of system operators. Therefore, choosing a proper control procedure to respond the grid disturbances is a crucial task. However, the strategic behaviours of generation companies lead to a competition between them which affects the control performance. In this thesis, an integrated mechanism is proposed that consider both dynamic and strategic behaviours of generation companies, at the same time with, its impact on frequency stability of the system. In this thesis, a dynamic market mechanism is proposed which optimally control transactions among generation companies, manage congestions of the grid, and preserve minimum and maximum limitations of generators. The proposed integrated market mechanism considers primary, secondary, and tertiary levels of load-frequency control loops. Moreover, the impacts of proposed integrated market mechanism on mentioned three levels are described. Another subject of this study is uncertainties in the system parameters and modeling. With growth of renewable power plants penetrations, daily variations of system parameters are increased.In addition, due to the uncertainties and inaccuracy of system modeling, using robust control would be necessary. In this thesis, a robust control is designed for such condition by using robust control theorems. Finally, the performance of proposed mechanism and control parameters are evaluated in the case study section.
