TToday’s world suffers from an increasing dependence on fossil fuels, which are finite and whose unbalanced distribution in different regions causes political conflicts. Furthermore, burning these fuels adversely affects the environment and results in global warming. Thus, renewable energy systems (RES), such as PV systems, could support the future need and lead to a sustainable environment. The main problem of PV is that the resource is intermittent. This problem could be relieved by coupling the PV system with an energy storage system. This study assesses two different storage systems, electrolyzer-fuel cell (EFC) and battery (BESS), for a PV power plant at a METU campus. The PV plant is sized as 4.5 MW which would generate electricity to meet the annual demand, whereas the storage systems are initially sized as 467 kW based on the average deficit energy of the campus. The preliminary, main results are presented in the table below. As the table indicates, the annual fraction of the demand supplied by the system (RES Fraction) without storage is 49.6%; this fraction is increased by 6.2% and 2% by installing EFC and BESS, respectively. Besides, the autonomy fraction also increased by 1.5% and 2.1% utilizing EFC and BESS, respectively, compared to the system without storage. Although the RES fraction of EFC is higher than BESS, the autonomy of BESS is a bit greater than EFC. The full version of the paper will include LCOE and another sizing method based on LCOE and the grid tariff.

MODELING AND SIMULATION OF A COMBINED SYSTEM OF MULTIPLE ROOFTOP PV SYSTEMS AND A CENTRAL ENERGY STORAGE SYSTEM FOR METU ANKARA CAMPUS Köker, Nesrin Irmak; Akınoğlu, Bülent Gültekin; Özden, Talat; Department of Earth System Science (2022-9-01) Climate change, increasing energy demand, and natural resource depletion lead to a rapid trend in the adaptation of renewable energy technologies. Especially solar energy as the most abundant source, accompanied by decreasing system prices and increasing social acceptance, rooftop photovoltaic systems became one of the most common small-scale energy generation practices. However, renewable energy resources, solar energy exclusively, create imbalanced energy production throughout the day and year. Energy sto...
Comparison of BEST and LEED green building rating systems through cost based optimization Uğurlu, Bengisu; Aksoy, Ayşegül; Department of Environmental Engineering (2020-1-25) Buildings have significant effects on climate change due to vast resource consumption and pollution generation. Improving the effective use of limited resources and constructing environmentally friendly buildings are important in the realm of mitigations for climate change. Several countries have their green building rating systems tailored towards their regulations, distinctive climatic conditions, unique cultures and traditions, diverse building types and ages, or wide-ranging environmental, economic, and...
An evaluation on adoption factors of spatial decision support systems in planning Erken, Şeyma; Pınarcıoğlu, Mehmet Melih; Department of Regional Planning (2021-6) Changes in production and consumption patterns as a result of globalization are leading to ever-increasing carbon dioxide emissions and environmental problems. As a result of this situation, climate change and global warming are getting more and more important. In addition to the environmental problems that are associated with increased carbon emissions, economic losses and human health threats are emerging. Today new models and approaches are being developed to reduce the destructive effects of such enviro...
Technical potential of rooftop solar photovoltaic for Ankara: A preliminary study Kutlu, Elif Ceren; Akınoğlu, Bülent Gültekin; Soytaş, Uğur; Department of Earth System Science (2020-9) Cities are responsible for over two-thirds of total energy consumption due to the population's externalities. The buildings in the urban areas cause half of this energy consumption. 250 cities have 100% renewable energy target worldwide, including nineteen metropolitans such as London, Los Angeles, Tokyo, and Paris. Besides, these metropolitans aim at zero emissions in new buildings by 2030 and in the existing ones by 2050. By year of 2018, as a developing country, Turkey has a dependency ratio of 73.8 % fo...
EXPLORING THE WAYS FOR INTEGRATING THE GREEN BOND WITH DECOUPLING PROJECTS THROUGH MONITORING AND EVALUATION: THE CARBON EMISSION ATLAS AND EXPERT SYSTEM (KAUS) Çavuşoğlu, Şevval; Ataöv Demirkan, Anlı; Department of City and Regional Planning (2022-4-28) More research in recent years has highlighted that the climate crisis is a consequence of the immense release of carbon emissions due to human activities. The negative side of the climate crisis is that it has led to severe environmental problems around the globe, which has negatively affected urban settings. Environmental-sensitive planning approaches can help reduce carbon emissions. One effective way to do that is reducing the energy use in cities and gaining the human behavior to become carbon-neu...
