The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro storage (PHS) as a long-term ESS, (2) with batteries as a short-term ESS, and (3) without ESS. The PV and wind sizes are optimally determined to accomplish the maximum annual RES fraction (F-RES) with electricity cost lower than or equal to the utility tariff. Furthermore, the effect of the use of battery and PHS on the electricity cost and F-RES are studied. A university campus on a Mediterranean island is selected as a case study. The results show that PV-wind hybrid system of 8 MW wind and 4.2 MW PV with 89.5 MWh PHS has the highest F-RES of 88.0%, and the highest demand supply fraction as 42.6%. Moreover, the results indicate that the economic and technical parameters of RESs are affected significantly by the use of ESSs depending on the type and the capacity of both the RES and the ESS.

The necessity for technical-economic analysis of solar energy systems is obvious when assessing their feasibility vis-á-vis conventional alternative systems. Optimum magnitudes of the installation parameters should be defined under the required economic conditions. In this study, the optimization procedure was chosen so as to maximize the total accumulated saving throughout the economic lifetime of the system. The annual solar heating fraction of the system is assessed using the f-chart method which can be ...
Evaluation of hybridsolar-wind-hydrogenenergy system based on methanol electrolyzer
Budak, Yagmur; DEVRİM, YILSER (Wiley, 2020-10-01)
In this study, it is aimed to meet the annual electricity and heating needs of a house without interruption with the photovoltaic panel, wind turbine, methanol electrolyzer, and high temperature proton exchange membrane fuel cell system. The system results show that the use of the 2 WT with 18 PV was enough to provide the need of the methanol electrolyzer, which provides requirements of the high temperature proton exchange membrane fuel cell. The produced heat by the fuel cell was used to meet the heat requ...
Statistical analysis of solar radiation data
Yilmaz, E.; Cancino, B.; Parra, W. R. (Informa UK Limited, 2007-01-01)
Solar radiation is the most important parameter in the design and study of solar energy conversion devices. The present work is based on statistical analysis of solar radiation data for the city of Valparaiso in the coast region of Chile. Experimental data were obtained from the Santa Maria University in Valparaiso over a five-year period measured by the actinograph and the pyranometer. The error between the actinography values in relation to the pyranometer ones was determined. The most frequent error perc...
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 ...

Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (Informa UK Limited, 2016-01-01)
In this study, the potentiality and economic viability of solar photovoltaic (PV) in Ghana was assessed using RETScreen software. 5 MW of grid-connected solar PV power system using SunPower SPR-320E-WHT-D PV module can be harnessed from Navrongo, Bawku, Wa, Tema, Bolgatanga, Axim, Salaga, Kintampo, Kete Krachi, Tamale, Hohoe, Koforidua, Ejura, Takoradi, Bole, Sunyani, Bibiani, Cape coast, Prestea, and Akuse, which requires US$17,752,179 of investment capital and 25,313 m(2) of land for PV installation. The ...
