Optimizing Small-Scale Wind Energy Generation: Site-Specific Wind Speed Analysis and Turbine Placement Strategies
Wind is an effective renewable power source suitable for localized electricity production when regional environmental factors have substantial impact on system output. The research studies the best wind turbine placement through wind speed variability studies conducted with calibrated anemometers and data loggers that assess site conditions. A data-based assessment method creates the research's main contribution which facilitates the optimization of wind power potential measurement for enhanced energy efficiency. The research methodology includes continuous Vantage Pro2 equipment together with anemometers at different heights for wind speed observation while performing accuracy-based calibration analysis. The research shows that elevating the turbine from seven meters to ten meters leads to a 12 percent growth in the amount of power produced. The power output of wind energy decreases as wind speed changes because of environmental conditions so proper installation locations become essential. Energy performance increases best when selecting sites which feature reliable and elevated wind speeds. This research provides useful knowledge about enhancing decentralized power generation through wind energy but it cannot be easily scaled up to bigger systems. The study demonstrates that specific site assessments together with practical recommendations will enhance the efficiency of small-scale wind energy systems.

Determination of I-V curves for photovoltaic generator by an analytical method; Akbaba model
In order to maximize the amount of electrical energy generated and ensure effective use, the conventional I-V or V-I characteristics derived from the diode model of Photovoltaic (PV) Solar Panels are important. Unfortunately, these features cannot be extracted using linear equations. It follows that the answer requires extremely drawn-out, time-consuming procedures. Many studies focus on calculating maximum power extraction. The analytical solutions to these equations are also nonexistent. Programming on computers can assist in solving the equations. The Akbaba Model was created specifically for the PVG to address these challenges. The Akbaba Model relies heavily on coefficients A, B, and C in this equation. The diode model serves as the true model in this case, and the coefficients A, B, and C are calculated. Another advantage of this model is that, because its qualities have partially deteriorated with time, the genuine I-V characteristics of the PV Panels can be recovered by measuring again.

Hummers ve Askorbik Asit ile Kimyasal İndirgenme Metotlarında Döngüsel Yaklaşım
Grafitten, Hummers metodu ile sentezlenen grafen oksidin ve sonrasında grafen oksitten kimyasal indirgenme metodu ile sentezlenen indirgenmiş grafen oksidin, pek çok kullanım alanlarına sahiptir. Bu çalışmada döngüsel yaklaşım ile grafen oksit ve indirgenmiş grafen oksit sentezlenmesi hedeflenmiştir. Bu hedef ile grafitten, Hummers yöntemi ile grafen oksit ve ardından kimyasal indirgenme metodunda askorbik asit kullanılarak indirgenmiş grafen oksit sentezlenerek birinci döngü tamamlanacaktır. Birinci döngüden sentezlenen indirgenmiş grafen oksit ikinci döngüde grafit yerine Hummers yönteminde kullanılarak döngüsel yaklaşım hedeflenmiştir. Döngü prosesi ile dört farklı grafen oksit ve indirgenmiş grafen oksit örnekleri elde edilmiştir. Sentezlenen her bir döngüye ait grafen oksit ve indirgenmiş grafen oksit örneklerinde, FTIR, RAMAN, BET, ZETA-SİZER ve SEM-EDS analizleri ile döngüsel yaklaşımda grafen oksit ve indirgenmiş grafen oksit örneklerinin karakterizasyonu gerçekleştirilmiştir. Döngüsel yaklaşım ile grafen oksit örneklerinde oksidasyon derecelerinin artması ile yapıdaki kusurlu bölgelerinin artığı, indirgenmiş grafen oksit örneklerinde ise oksidasyon derecelerinin azalması ile yapıdaki kusurlu bölgelerinin azaldığı tespit edilmiştir.

The comparison study of PI and Sliding Mode control techniques for Buck-Boost converters
This paper compares the performance of a Sliding Mode Control (SMC) and Proportional-Integral (PI) controller under different voltage and load conditions. The study's findings underscore the need to account for load variations in system designs and to continuously seek system optimization irrespective of the controller type chosen. PI controller demonstrates effectiveness under certain circumstances. However, significant drops in voltage and current during abrupt load changes are obtained. On the other hand, SMC enables superior adaptability, efficiently managing voltage transients and load variations without any electrical disturbances, thereby maintaining system stability. A comparative analysis further emphasizes the SMC's superior time response and robustness against reference voltage changes. Consequently, SMC is proven to be a preferable choice over the PI controller in systems experiencing frequent voltage and load variations. However, both controllers achieve the potential for further response time optimization and stability.

Mikro Şebekeler için Enerji Yönetimi ve Gerilim Kontrol Algoritmalarının Geliştirilmesi: Alçak Gerilim Seviyesinde Statik Voltaj Regülatörü Örneği
Son yıllarda dağıtık enerji üretiminin artması ile birlikte alçak gerilim (AG) tarafta, tüketici geriliminde yükselmeler meydana gelmektedir. Aynı zamanda ters güç akışı, şebeke dengesizliği gibi problemler ile birlikte gerilimdeki yükselme, enerji hatları üzerinde kayıplara yol açarak sistemi veriminin düşmesine neden olmaktadır. Bu makalede, AG mikro şebekeler için gerilim problemlerinin çözümüne yönelik, mikro şebeke önüne statik voltaj regülatörü (SVR) bağlanmıştır ve SVR gerilim kontrol algoritması geliştirilmiştir. Gerilim kontrol algoritmasının mikro şebeke için önerilen Kural Tabanlı ve Optimizasyon Tabanlı Enerji Yönetimi Sistemleri (EYS) ile birlikte uygulanmasına yönelik benzetim çalışması yapılmıştır. IEEE 13 bara test sistemi ve önerilen algoritmalar Simulink/MATLAB ortamında oluşturulmuştur. Optimizasyon tabanlı EYS sonuçları, Python programlama dili kullanılarak elde edilmiştir. Gerçek gerilim ve yük profili otomatik sayaç okuma sistemi (OSOS) verilerinden alınmıştır ve elde edilen sonuçlar SVR gerilim kontrol algoritmasının, mikro şebekelerinin gerilimini istenilen seviyeye indirilmesinde etkili bir şekilde kullanılabileceğini göstermiştir. Aynı zamanda Optimizasyon Tabanlı EYS ile mikro şebekelerin daha efektif bir şekilde yönetilebileceği benzetim çalışması sonuçları ile doğrulanmıştır.

GA Based Selective Harmonic Elimination for Five-Level Inverter Using Cascaded H-bridge Modules
Multilevel inverters (MLI) have been commonly used in industry especially to get quality output voltage in terms of total harmonic distortion (THD). In addition, development in semiconductor technology and advanced modulation techniques make MLI implementation more attractive. Selective Harmonic Elimination (SHE) that can be applied MLI at desired switching frequency offers elimination of harmonics in the output voltage. Also, by using SHE technique with cascaded multilevel inverters, the necessity of using filter in the output can be minimized. In this paper, SHE equations have been solved by using of Genetic Algorithm (GA) Toobox&Matlab and it has been aimed to eliminate desired harmonic orders at fundamental output voltage. Simulation results have clearly demonstrated that GA based SHE techniques can eliminate the demanded harmonic orders.
