Energy resources and global warming are two of the most important concerns for the whole world, where the necessity of finding clean and cheap energy resources have high priority nowadays. Renewable Energy Systems (RES), such as PV power plants and wind turbines, have the ability to meet the demand of the world; however, the energy generation of these kind of systems does not fully match with the electrical energy demand. Having a diversity of RESs with Energy Storage System (ESS) will increase the matching between the energy generation and the energy demand. The purpose of this thesis is to determine the sizes of different Renewable Energy Micro-Grid (REMG) systems with four main ESS scenarios with and without taking the ESS depth of discharge (DOD) into consideration; (1) without ESS, (2) with short term ESS-batteries, (3) with long term ESS-Pumped Hydro Storage (PHS), (4) with hybrid short and long term ESSs- batteries and PHS- for a university campus on a Mediterranean island in order to achieve the maximum yearly RES fraction () with Cost of Electricity (COE) equal or lower than the local grid tariff. Moreover, this study aims to determine the optimal ESS sizing methodologies with different RESs in order to achieve this goal. In addition, a sensitivity analysis of the models is carried out to determine the sensitivity of the RESs to the fluctuation of meteorological data in addition to the variation in the demand. Moreover, the effect of the integration of different ESS scenarios on the COE, , demand supply fraction (DSF) and the feasible sizes of PV, wind, PV/wind hybrid systems is studied in addition to the effect of the DOD of the ESS on these parameters. The results indicate that the PV/wind hybrid system with 4.19 MW PV, 8 MW wind and 89.51 MWh PHS has the highest - 88.04%- among the other RESs while the PV/wind hybrid system with 3.44 MW PV, 8 MW wind, 833 kWh battery and 89.51 MWh PHS has the highest DSF- 80.74%- with COE equal to the grid tariff. Moreover, the results indicate that the integration of ESS affects the economic and technical parameter of the RES where these effects vary based on the RES type, ESS type and RES capacity. Furthermore, the results show that the DOD of the ESS is a vital parameter that affects the optimal ESS sizing methodologies and the economic and technical parameters of the RES.

A techno-economic feasibility study of a gridconnected hybrid solar pv-wind power generation system in Zimbabwe Samu, Remember; Fahrioğlu, Murat; Sustainable Environment and Energy Systems (2019-1) The depletion of fossil fuel resources on a worldwide basis and an increase in greenhouse gas emissions and climate change as a whole have caused an urgent search for alternative sustainable energy sources to cater for the rising energy demands. The demand of energy is rapidly growing in both developing and developed nations thus making hybrid renewable energy power systems (RES), comprising Solar Photovoltaic (PV) and wind energy to be chosen as one of the best alternatives. However, on the downside, these...
Rethinking wind energy in its social context: conflicting perspectives and planning problems – the Karaburun experience Özçam, Zeynep; Pınarcıoğlu, Mehmet Melih; Department of City and Regional Planning (2016) As a result of global concerns about energy related environmental problems, the use of renewable energy resources has gained great importance. The renewables are widely recognized as an effective tool for limiting energy related emissions and a fundamental component of sustainable development. Among these, especially wind energy has considerable involvement. Due to this, major national policies intend to support wind energy and wind energy installations have also started to grow with an expanding rate. Like...
Feasibility Study of a Grid Connected Hybrid PV-Wind Power Plant in Gwanda, Zimbabwe Samu, Remember; Fahrioglu, Murat; Taylan, Onur (2016-10-14) The depletion of fossil fuel resources on worldwide basis has necessitated an urgent search for alternative energy sources to meet up the present day demands. Energy demand is growing in developing nations which makes a hybrid power system, consisting of a hybrid Solar Photovoltaic together with wind energy to be considered one of the best alternatives in renewable energy. These sources of energy can partially or fully meet Gwanda's demand with little or no disturbance on the country's stability. The object...
Impact of Urban Street Network on BIPV Generation Capacity of Buildings Duran, Ayca; Akgül, Çağla; Gürsel Dino, İpek (2022-10-11) Climate change necessitates a critical reconsideration of the built environment since buildings are among the top fossil fuel consumers. Solar energy generation through building integrated photovoltaic (BIPV) systems is one of the most common onsite energy generation methods. However, many factors regarding urban morphology can negatively affect BIPV generation. Urban block typologies and spatial patterns are commonly studied descriptive metrics of an urban morphology that affect the solar energy potential....
INVESTIGATION AND MODIFICATION OF HYDROKINETIC SAVONIUS TURBINE FOR LOW WATER SPEEDS Ike-Offiah , Chiedozie Augustine; Orang, Ali Atashbar; Oğuz, Elif; Sustainable Environment and Energy Systems (2022-11) With the ever-growing global interest in reducing greenhouse gases such as CO2, renewable energy options present a good energy alternative. Not only are they a sustainable option in their operational period, but they also have a low implementation cost especially, when compared to conventional fossil fuel sources. Hydrokinetic turbines have the advantages of energy predictability, relatively low visual impact, a high energy density, high capacity factor, and ease of manufacture, in addition to the low cost ...
