“…Moreover, adding more PV modules decreases the efficiency of the AC power conversion system because the output DC power from the photovoltaic string keeps increasing while the value of the AC power output at the single-phase CSI output terminal does not change. Where Pout represents the AC power output of the single-phase CSI, Pin is the DC power input of the single-phase CSI [31][32][33][34][35].…”

“…The maximum efficiency power conversion system of 63.3% occurred when the voltage at maximum power of the PV string equaled the peak grid voltage source. The system is a current source inverter, and the power quality is based on voltage quality [31]. Therefore, the current waveform at the load as well as its magnitude is based on the nature of load impedance [36].…”

This paper presents the simulation of a simple single-phase grid-connected photovoltaic (PV) system using the PSPICE model. The modeling system consists of a PV string, a single-phase current source inverter (CSI), load, and a grid voltage source. The system uses the PV string as the current source. The single-phase CSI was controlled by the grid AC voltage. The operation of the system employs the negative conductance characteristics of the PV string. We studied the voltage and current waveform at the inverter output terminal, the current waveform at the load, the AC power with various open-circuit voltages and temperatures of the PV string. The result showed the current waveform at the inverter output terminal follows the I-V characteristics of the PV string. The current waveform at the load depends on its impedance characteristics. The AC power increased with the open circuit voltage. We found that the maximum efficiency of the AC power conversion system was 63.3% at the peak of the AC voltage source, which was equal to the maximum power voltage of the PV string. In addition, the prototype was built for testing and testing verified the simulation results. The experimental results showed the current waveform at the inverter terminal and load were similar to the simulation results.

“…Turbines with more blades operate at low speeds and have a higher initial power coefficient, but the coefficient decreases rapidly as the speed increases. Turbines with fewer blades operate at high speeds, and the power coefficient takes large values initially, but gradually decreases as the speed increases (Boulouiha, Allali, & Denai, 2017).…”

Konvansiyonel yanıcı (fosil) yakıtların (kömür, madeni yağ ve doğal gaz) rezervleri, bugünkü hızla kullanılması halinde 50 ila 200 yıl içinde tükenecektir. Doğal gaz, petrol, kömür veya nükleer gibi konvansiyonel enerji kaynakları sınırlıyken, rüzgar, güneş, biyogaz/biyokütle, jeotermal vb. gibi yenilenebilir enerji kaynakları temizdir ve doğada bol miktarda mevcuttur. Yenilebilir enerji kaynaklarından olan rüzgar enerjisi temiz, emisyonsuz bir enerji üretim teknolojisidir. Rüzgar enerjisi, üstün özellikleri, yenilenebilir enerji, geniş dağıtım ve sıfır kirlilik nedeniyle “yeşil enerji”nin ana destekçilerinden biridir. Bu çalışma, son yıllarda yapılan araştırmalara dayanarak rüzgar enerjisinin potansiyelini tartışmaktadır. Çalışmada öncelikle rüzgar enerjisi kavramı kapsamlı bir şekilde anlatılacak, rüzgar enerjisi kullanımının avantaj ve dezavantajlarına değinilecektir. Daha sonra rüzgar enerjisi santrali bileşenlerinden rüzgar türbinleri üzerinde durulacaktır. Rüzgar türbinleri türleri ve özellikleri açıklanacaktır. Son olarak Türkiye’nin rüzgar ve rüzgar enerjisi potansiyeli hakkında bilgi verilecektir. Araştırmanın sonuç kısmında ise araştırmada elde edilen bilgilere dayanılarak, Türkiye’nin rüzgar enerjisi gücünün gelişimine yönelik önerilerde bulunulacaktır.

There has always been a high expectation that wind generation systems would capture maximum power and integrate properly with the grid. Utilizing a wind generation system with increased management to meet the growing electricity demand is a clever way of accomplishing this. However, wind power generation systems require a sophisticated, unique, and dependable control mechanism in order to achieve stability and efficiency. To improve the operation of the wind energy conversion method, researchers are continually addressing the obstacles that presently exist. Therefore, it is necessary to know which control can improve the whole system’s performance and ensure its successful integration into the network, despite the variable conductions. This article examines wind turbine control system techniques and controller trends related to the permanent magnet synchronous generator. It presents an overview of the most popular control strategies that have been used to control the PMSG wind power conversion system. Among others, we mention nonlinear sliding mode, direct power, backstepping and predictive currents control. First, a description of each control is presented, followed by a simulation performed in the Matlab/Simulink environment to evaluate the performance of each control in terms of reference tracking, response time, stability and the quality of the signal delivered to the network under variable wind conditions. Finally, to get a clear idea of the effect of each control, this work was concluded with a comparative study of the four controls.
