Sizing, design, and installation of an isolated wind–photovoltaic hybrid power system with battery storage for laboratory general illumination in Afyonkarahisar, Turkey

Abstract

In this study, a battery-reinforced hybrid wind-solar power generation system of a size able to meet the electric power requirement for general illumination of the electric laboratory at Afyon IntroductionEnergy is the most important requirement in increasing the welfare level in the social life of humanity and the economic growth of countries. Energy sources used to meet energy needs and have changed during the historical process in parallel with technological developments. The reason for this is the steady increase in energy demand and steady decrease in fossil fuels used in energy consumption (Peidong et al., 2009). Greenhouse gas emitted during consumption of fossil fuels cause serious environmental problems and this disturbs people from all strata of society. Such energy sources cause global warming in addition to air pollution, formation of acid rain, and depletion of the ozone layer (Wai et al., 2008).Because of the consumable nature of energy sources, the existence of foreign dependency and the environmental effects, and the generation of cheap and clean energy in sufficient quantities for countries has become a current problem. For this reason, the efficient use of generated energy and good use of the potential for alternative and clean

Designing a solar and wind hybrid system for small-scale irrigation: a case study for Kalangala district in Uganda

“…When the metrological data of Kalangala district (wind speed and solar periods) are put into consideration, it is assumed that more benefit will be gained from solar energy than from wind energy. There are more advantages in using hybrid wind and PV solar technologies as compared to using them separately [23]. Figure 5 is the proposed system connectivity with two inverters, battery, controller, solar panels, wind turbine and charger controller.…”

“…By considering charge controller output at the wind turbine, and solar system as 95% (AC-DC) and 90% for (DC-AC) respectively, then the required power taking into account power efficiencies was calculated using Eq. 9 [23].…”

“…Oğuz [23] stated that if it is assumed that there might be general losses that might occur in the system considering the worst situations (cable losses, attachments, development current), then the total power needed per day can be obtained from Eq. 10 accounting for all lo8sses assumed to exist in the system.…”

“…According to Oğuz [23], the daily energy required of a wind turbine in amperes per hour can be obtained using Eq. 16.…”

“…Determining wind turbine blade radius From Eq. 17, the blade radius of the turbine capable of generating the desired power was calculated [23].…”
