Assessment of Optimal Power Flow (OPF)Uncertainty in Hybrid Wind- PV Power Systems
, M.Sc. Thesis Sharif University of Technology ; Fotouhi Firouzabad, Mahmoud (Supervisor)
Abstract
As a matter of fact, power systems are always faced with a variety of uncertainties. These uncertainties change system parameters in an unwanted manner which may deteriorate the system security and reliability. For instance, a transmission line which is designed for a certain capacity may be suffered as a result of load increment and consequently may influence the normal operation of other network elements. In recent years, as a result of environmental considerations and especially after the oil shock at 1973 which caused the the energy prices to increase unprecedentedly, the human has taken more attention to renewable energies exploitation. Theses energies have a fluctuating nature and are...
Operation Reserve Determination in a Power System Containing Renewable Generation
, Ph.D. Dissertation Sharif University of Technology ; Abbaspour Tehranifard, Ali (Supervisor) ; Fotouhi Firouzabad, Mahmoud (Co-Advisor)
Abstract
Renewable energy resources, e.g. wind, solar and geothermal, experience rapid progresses in electric power industry all over the world. So, it becomes essential that these free-emission electrical energy resources be integrated in the existing generating capacity planning procedures. On the other hand, the uncertain and intermittent nature of these energies has led to some problems in their integration in power systems. The reserve requirement in a renewable-based power system is a main challenge, which has to be addressed properly. In this way, this research presents an analytical approach, based on the modified PJM method, to quantify the risk of renewable energies commitment during the...
Analysis of Communication Infrastructure Failures in a Power System and Their Impacts on System Reliability
, M.Sc. Thesis Sharif University of Technology ; Abbaspour Tehrani Fard, Ali (Supervisor) ; Fotouhi Firouzabad, Mahmoud (Co-Advisor)
Abstract
The development of communication infrastructure in power systems has provided the grid with the availability of accurate information and has increased the reliability of the grid and its responsibility to disturbances. However, there have been some concerns about the negative impacts of the reliance on the information infrastructure. Inadequacies in the control and communication systems have been reported to be the contributing factors to situations that led to major blackouts. The functionality and reliability of the power grid is undoubtedly influenced by its communication infrastructure. In this thesis we are trying to model and analyze the failures that may occur in a power system and...
