Electricity has become one of the main pillars of a well-functioning society and hydroelectric power plants (HEPPs) are one of the main providers of energy in Turkey that are also renewable. To exploit the energy production capacity of existing HEPPs in Turkey and efficient usage of water, operational optimization could help immensely. A non-linear constrained optimization algorithm with an extension, namely a heuristic that provides starting points, has been implemented to maximize the energy production of a cascade HEPP system based on monthly inflow data. A cascade of four dams along the Murat River, which is one of the two main streams of Euphrates River at the Eastern part of Turkey, was studied to test the abilities of the mentioned algorithm. A 40-year average monthly flow data was used as input and results of cascade and single optimization were compared. Results showed that the developed MATLAB® script can converge to an optimum solution that satisfies the constraints. The comparison study made with individual runs of each HEPP showed that a 5% higher energy production was attained with the cascade variant. A drawback was the higher computational time (which was still within comparable limits), which can be further improved by implementing more efficient algorithms.

Alternative feasibility studies for Altıparmak Dam and HEPP Ak, Mümtaz; Kentel Erdoğan, Elçin; Yanmaz, Ali Melih; Department of Civil Engineering (2011) Hydropower is the most important domestic energy source of Turkey. Thus, wise planning and development of the unused hydropower potential of the country is vital. There are many hydroelectric power plants under planning stage in our country. Altıparmak HEPP is one of them. General Directorate of Electrical Power Resources Survey and Development Administration (EİE) and ANC Enerji conducted two separate feasibility studies for Altıparmak HEPP in 2001 and 2009, respectively. Traditionally, the energy income c...
Optimisation of the Tigris river hydropower system operations Yalçın, Emrah; Tiğrek, Şahnaz; Department of Civil Engineering (2015) Growing external energy dependence and rising oil prices are encouraging Turkey to turn to renewable energy, especially hydropower. The amended legislation on the transference of the operational rights of existing, under-construction and planned hydropower plants to the private sector and the allocation of water right licenses to develop new projects for electricity production has led to a drastic decrease of the public share in production. Consequently, conflicts related to the operation of reservoirs have...
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...
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...
Market development of renewable energy in Turkey Demirdizen, Hasan Gence; Tiğrek, Şahnaz; Department of Civil Engineering (2013) Renewable energy is a current issue in the world as well as in Turkey. Turkey has developing policies in the renewable energy field. Although it is a beneficial mean of obtaining energy, there are barriers on renewable energy production. In order to develop renewable energies, those barriers have to be analyzed and suitable implementations should be developed to overcome them. In this thesis policy and implementation on the renewables are evaluated in general and specially for Turkey. The electricity market...
