Özet:

Energy models containing renewable energy sources are needed to reduce the share of fossil fuels in electricity production. However, renewable energy sources are often irregular and intermittent sources of energy and are unpredictable. The design of hybrid systems that enable the common use of alternative resources and the use of energy warehouses are one of the methods used to reduce the difficulties in the use of these resources and to design cost-effective and reliable systems. The most commonly used storage form in the world, especially in large-scale systems, is the storage of energy in pumped stored hydroelectric power plants (PHES) in the potential energy form of water. PHESs can be designed as pure systems if there is water entrance from the outside, and if there is no, they can be designed as pure systems. This study offers a two-stage stocastic programming model in a way that will take into account the uncertainty in the sources and demand of both PHES systems. With this study for the first time in literature, the hybrid systems that are supported by separate pure PHES and mixed PHES of the solar energy production facility that can be established to meet a specific electricity demand have been addressed and the results are presented in the form of a case analysis for Turkey, which is based on high levels of fossil fuels, despite the high potential of any PHES system and renewable energy sources.
