Feasibility study for hybrid power plants: The case of Karacaören-2 dam and hydroelectric power plant

The central objective of this thesis is to evaluate the potential for Turkey to generate renewable energy, a nation that is heavily reliant on imported energy resources. The thesis further aims to propose sustainable solutions that will enhance energy supply security. In this regard, a hybrid energy system that integrates hydropower and wind power has been conceptualised. The selected study area is the Karacaoren-2 Dam and Hydroelectric Power Plant, located on the Aksu River in the Mediterranean Region. A Pumped Hydro Energy Storage (PSH) system is planned near the existing dam. The area's substantial wind energy potential facilitates the development of a hybrid wind-PHES energy plant. The study incorporates technical, economic, and environmental analyses, with a focus on the complementary nature of PHES and wind energy systems. The proposed hybrid system aims to supply the necessary energy for PHES storage processes using renewable energy generated by wind turbines. The promotion of PHES systems is imperative for addressing Turkey's electricity supply-demand imbalances. The utilisation of hybrid energy sources is advocated in order to enhance the efficiency of these systems. The economic analyses indicate that the proposed hybrid system is economically viable and contributes significantly to energy supply security. This study is also significant as a reference point for the promotion of hybrid energy solutions in Turkey.
