    An investigation on wind/PV/fuel cell/battery hybrid renewable energy system for nursing home in Istanbul
    (Sage Publications Ltd, 2019) Dursun, Bahtiyar; Aykut, Ercan
    This paper presents a techno-economic analysis of hybrid renewable energy systems to supply the electrical load requirements of the nursing home located in Istanbul, Turkey. The standalone hybrid renewable energy systems (Photovoltaic (PV)/wind/fuel cell/electrolyzer, PV/fuel cell/electrolyzer, and wind/fuel cell/electrolyzer, etc.) considered in the analysis were comprised of different combinations of PV panels, fuel cells, and wind turbines supplemented with hydrogen storage. In this study, the Hybrid Optimization of Multiple Energy Resources (HOMER) software is used as the assessment tool to determine the optimal configuration of hybrid renewable energy systems taking total net present cost and cost of energy into consideration. As a result, it is determined that the optimal system configuration of standalone wind/PV/fuel cell/electrolyzer hybrid renewable energy systems with the lowest total net present cost consists of 30 kW PV panel, 20 kW wind turbine, 20 kW fuel cell, 20 kW power converter, 50 kW electrolyzer, 20 kW rectifier, and 100 kg hydrogen tank. Besides, the net present cost and cost of energy of the optimum configuration are calculated to be $607,298 and $1.306/kWh, respectively. The system is considered as completely renewable. When wind speed and solar radiation values increase, then the cost of energy decrease about $0.979/kWh.

    Determination of Hybrid Renewable Energy Systems for Project Type Public Library Building
    (Int Journal Renewable Energy Research, 2019) Altay, Ahmet; Dursun, Bahtiyar
    In this context, the most convenient hybrid renewable energy system (HRES) option for the public libraries, which give services in the project type service buildings within the General Directorate of Culture and Tourism Ministry, will be chosen by evaluating the potentiality of renewable energy sources of region. In this way, both the usage of the most convenient energy source and the efficient usage of energy will be supplied. The public Library in Kirklareli City has been chosen as the example for the project type service building in this study. The most convenient option among HRES options is determined by evaluating the all energy sources potentiality of Kirklareli for the service building of Kirklareli City Public Library. It is calculated that the most appropriate HRES is PV/wind/battery for the library. The predicted total project cost of HRES is estimated to be 119,492$ and unit energy cost is determined as 2.01$/kWh for the library.
