This study is a part of a refurbishment project, which renews the hydro-mechanical speed governor of a hydroelectric power plant (HEPP) with a new digital one. Based on the previous study of the project, which covers the validation of the HEPP model, the simulation studies implemented in Matlab/Simulink environment are conducted to design the best controller philosophy for the digital speed governor controller. In order to be able to give satisfactory response to the load frequency control of the power system, the speed governor should respond to the set point changes as quickly as possible within the safe margins. In order to compensate unsatisfactory performance indices of conventional proportional-integral (PI) controller, a new controller based on the differential flatness theory is designed. The new controller is constructed by adding on a flatness-based feed forward part to the existing PI feedback controller, which results in improved performance compared to the conventional PI controller.

A decision support tool for feasibility assessment of hydro electrical power plant projects Ercan, Noyan; Birgönül, Mustafa Talat; Dikmen Toker, İrem; Department of Civil Engineering (2011) The objective of this thesis is to develop a decision support tool to assess the feasibility of a hydro electrical power plant (HEPP) investment option by estimating its profitability under various scenarios. The decision support tool may help the decision makers to understand critical parameters that affect the internal rate of return (IRR) of a HEPP investment, create realistic scenarios by assigning different values to these parameters and monitor profitability under various scenarios. The information an...
Improving Capacity Factor of Transmission Lines by Hybridizing CSP with Wind Rashid, M.; Abujubbeh, M.; Fahrioglu, M. (2017-04-10) Due to intermittent behavior of generated wind power, capacity factor of installed transmission lines decreases, which in return increases the payback time and also limits the grid penetration of the wind power plant. One option to compensate this is by using fossil fuel back up, but it is not a sustainable option due to the increased greenhouse gas emissions associated with fossil fuels. Another option is to couple a concentrated Solar Power (CSP) plant, provided there are ample solar resources available. ...
Improved wind power forecasting using combination methods Köksoy, Ceyda Er; Birtürk, Ayşe Nur; Karagöz, Pınar; Department of Computer Engineering (2015) Wind is an important renewable energy source to produce electricity thanks to its reliable, omnipresent and economically feasible characteristics and it has a growing proportion in overall energy production worldwide. However, integration of the generated wind power into the existing transmission grid is an issue due to inherently volatile and intermittent behavior of wind. Moreover, the power plant owners need reliable information about day-ahead power production for market operations. Therefore, wind powe...
Future Electrical Generator Technologies for Offshore Wind Turbines Keysan, Ozan (2015-01-01) In this article, different electric generator topologies for offshore wind turbines will be reviewed. Although, the most common generator type used in the onshore wind turbines is the doubly-fed induction generator, different generator designs are proposed for large offshore wind turbines, which operate in harsher conditions and are difficult to maintain. Some of these designs are direct-drive permanent magnet generators, hydraulic power take-off systems and superconducting generators.
Development of the rule curve for Altıparmak hydroelectric power plant Boyacıoğlu, Şerife Ece; Kentel Erdoğan, Elçin; Yanmaz, Ali Melih; Department of Civil Engineering (2013) Energy requirement of Turkey increases day by day and hydropower is currently the main renewable energy source of the country. Thus, planning the development of the unused hydropower potential of Turkey is critical. Available water resources have to be developed and managed in a wise manner. Reservoir operation rule curves are fundamental guidelines for long term reservoir operation. Rule curve which results in the maximum energy generation has to be developed for each hydropower plant (HEPP). The goal of t...
