A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…

The unlimited nature of consumption and needs contrasts with the scarcity of usable resources, necessitating the optimal use of available resources. Alongside the careful protection of the environment and human health, it is crucial to meet needs with maximum …

Günümüzde gelişen teknolojiyle birlikte artan sera gazı emisyonları ve küresel ısınma problemleri yenilenebilir enerji kaynaklarının kullanımını önemli ölçüde artırmıştır. Yenilenebilir enerji kaynakları güneş enerjisi, rüzgar enerjisi, jeotermal enerji, hidro…

The cell temperature of a photovoltaic (PV) module increases with increasing irradiation rate, and this increment adversely affects the output power or the electrical efficiency of the PV module. Therefore, in the present study, a series of experiments are p…

Here we discussed the electrical performance of Photovoltaic (PV) panels of natural dust accumulation by wind, bird droppings etc., over time which is of great importance especially for the areas where the rain density are high [1, 2]. In this study, the eff…

The aim of this study is to determine instantaneous irradiance and annual percentile sunlit time on the available rooftop floor area of Technical and Social Science Vocational School at Usak University by simulation using open source software. The building of …

Fossil fuels used by traditional internal combustion vehicles today are quite damaging to environment. Because of these fuels, global warming has reached a very dangerous point. However, fossil fuels are gradually depleting. Therefore, it is inevitable that el…

Solar photovoltaic (PV) systems are widely adopted for sustainable energy production; however, physical defects such as glass breakage significantly reduce panel efficiency and system output. In this study, a real-world case analysis was conducted on a 1003 kW…

Artificial lighting is an important part of global electricity consumption. At office buildings, the energy consumed by artificial lighting can reach up to 40% of total energy consumption. This work is being done to find solutions to such problems with energy …

Günümüzde, enerji ihtiyacının karşılanmasında fosil yakıtların kullanımı sınırlı kaynakları ve çevresel etkileri nedeniyle sürdürülemez hale gelmiştir. Bu durum, temiz, çevreci ve sürdürülebilir alternatiflerin, özellikle güneş, rüzgâr ve biyokütle gibi yenile…

A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…

Fotovoltaik (FV) sistemler birkaç W’dan, MW’a kadar ölçeklendirilebilmesi gibi özelliklerinden dolayı en çok yaygınlaşan yenilenebilir enerji kaynağı türüdür. Bu enerji kaynağından en yüksek oranda yararlanılabilmesi maksimum güç noktasını izleyen (MPPT) dönüş…

İhtiyaç duyulan enerji talebinin büyük bir bölümü petrol, doğal gaz, kömür gibi fosil ve nükleer yakıtlardan elde edilmektedir. Elektrik tüketiminin sürekli artması, kullanılan kaynaklarının çoğunun fosil kökenli olması ve bu kaynakların elde edilme zorluğu dı…

When the traditional fuel reserves are limited and the environmental factors of these fuels are taken into consideration, the importance of renewable energy sources is increasing day by day. Especially, obtaining electricity from solar energy has become popula…

The utilization of renewable energy sources is being enlarged daily to meet the escalating energy needs around the world. Solar energy, like other renewable energy sources, occupies an important place in the energy generation sector. Since it is important to i…

Yapılan bu çalışmada, Ankara ili merkezinde bulunan bir kampüsün bazı binaların elektrik ihtiyacının fotovoltaik sistemlerle karşılanılmasının istenmesi durumunda tasarlanacak sistemden üretilebilecek enerji miktarının ve sistemin performans oranın simülasyon …

Using a lens to concentrate sunlight and focus it on smaller sized solar cells increases the system’s output power and in the same time decreases the cost by replacing much of the expensive semiconductor photovoltaic cells with the cheaper optics. But the conc…

In this study, a single switch cascade DC/DC boost converter has been preferred instead of conventional cascade DC/DC boost converter to reduce cost and provide simple system control. High-performance controller design for DC/DC converters is the most importan…

In the study synchronization was studied using an all-to-all network structure in a multiple system of Kuramoto oscillators. Synchronization performance was first investigated in a weakly connected system, and the effects of link strength and number of oscilla…

Asynchronous motors are the most preferred engines in the industry due to factors such as their stable speed, economic and operational safety. Recently, asynchronous motors have been used as generators in the power generation sector and especially in wind turb…
