Renewable energy usage has become widespread and gained world-wide importance lately. In order to get high quality power from renewable energy sources to the grid, bulk energy storage system will be required as a buffer, due to the intermittent nature of renewable energy. Advanced adiabatic compressed air energy storage (AA-CAES) technology is uniquely different from conventional energy storage techniques for renewable energy in that it captures and stores the heat generated during the compression cycle and releases this heat in the expansion cycle. In this thesis, a new method is developed for sizing and assessment of adiabatic compressed air energy storage system (AA-CAES) as a buffer for wind energy production taking into consideration the indeterminacy of the wind resource and variations in electrical demand. In this methodology, a specific place in which the wind farms and very large air storage cavern are located is selected for the system construction. For that specific place, the hourly electricity production for the wind farm is calculated according to wind speed taken from TMY2 data by using power output graph for specific wind turbines. Additionally, hourly power consumption of the selected place is taken according to energy consumption data of the selected place. These generation and consumption values are compared and hourly energy storage and energy production algorithms are developed. For this method, components used during the energy production and storage process such as compressor, turbine and thermal energy storage tank are separately examined and modeled in MATLAB software platform. According to the energy production and storage algorithms, sizing of packed bed thermal energy storage tank and air storage cavern are studied by using a simplified packed bed thermal energy storage method, and this method is verified with experimental data in the open literature. In addition, several parametric studies related to the sizing and properties of the system components are performed and the effect of these to the system performance is evaluated. Finally, the total system efficiency is calculated and compared with existing AA-CAES concepts. To demonstrate this method, the power generations of DARES Datça wind farm according to TMY2 data and power consumption of Datça peninsula, which is calculated indirectly from total Aegean Region power consumption data, values are used as input values.

Numerical comparison and sizing of sensible and latent thermal energy storage for compressed air energy storage
Kaya, Mine; Tarı, İlker; Baker, Derek Keıth; Department of Mechanical Engineering (2015)
Intermittent and variable characteristics of renewable energy systems can be compensated by energy storage systems (ESS). There is a wide range of ESS specialized for different applications. Compressed Air Energy Storage (CAES) is often used for wind power plants due to high power rating at the discharge and long discharge duration. CAES takes ambient air and pressurizes through a compressor and stores compressed air in a volume when supplied energy is greater than demand. If demand exceeds supply, CAES is ...
Preliminary Study on Site Selection For Floating Hybrid Wind And Solar Energy Systems In Turkey
Yerlikaya, Nevzat Can; Çakan, Çağatay; Başara, Ilgın; Caceoğlu, Eray; Huvaj Sarıhan, Nejan (2021-09-08)
It is well-known that even though fossil fuels are the main energy resource in Turkey, use of sustainable energy resources such as wind and solar energy has been increasing in the past years and expected to continue on this trend in the next years to come. The suitable land for land-based wind turbines and photovoltaic (PV) systems could also be convenient for various other purposes, such as agriculture. This study aims to investigate the suitable sites for a combined floating wind and solar systems in the ...
Overcoming problems in Turkey's renewable energy policy: How can EU contribute?
Sirin, Selahattin Murat; Ege, Aylin (2012-09-01)
Fossil fuels cover most of the energy demand in the world, and this creates significant social, economic and environmental problems. Many countries have taken measures to increase the share of renewable energy sources (RES), especially in electricity generation, and the review of literature shows that the success of a country in RES diffusion depends on a comprehensive renewable energy policy which combines political commitment with stable and long-term support measures that stimulate technological innovati...
Improving the energy conversion stability of hybrid solar photovoltaic / wind turbine renewable energy systems
Aşçıoğlu, Berk; Batunlu, Canraş; Electrical and Electronics Engineering (2019-8)
In the last few years, renewable energy sources such as wind turbines, photovoltaics, hydropower stations etc. have become widespread because of raising energy needs of the world. Since the fossil fuel consumption excessively has increased, lack of energy has caused the renewable energy requirement. Furthermore, renewable energy has an important role because of the economic and environmental worries. In other words, industrial and inhabitant needs by provided the traditional energy is no longer a successful...
A review of the optimization studies for Savonius turbine considering hydrokinetic applications
Maldar, Nauman Riyaz; Ng, Cheng Yee; Oğuz, Elif (Elsevier BV, 2020-12-15)
© 2020 Elsevier LtdThe trend of utilizing renewable energy sources is witnessing a brisk growth around the world. Among the various sources of renewable energy, hydropower is considered the most favorable due to its high potential and distinct advantages such as predictability, high energy density etc. Moreover, to extract the hydrokinetic energy from flowing streams, different designs of hydrokinetic turbines have emerged which operate on a similar principle as the wind turbines. The Savonius turbine is a ...
