Artan küresel enerji talebi ve değişken maliyetler, insanoğlunu sürdürülebilir ve düşük maliyetli enerji çözümlerine yönlendirmektedir. Yenilenebilir kaynaklar ve buna benzer enerji üreten teknolojiler, ekonomik ve çevre dostu seçenekler olarak öne çıkmaktadır. Son yıllarda enerji üretim maliyetlerindeki ciddi azalma ile güneş enerjisi ön plana çıkmıştır ve milli ekonomiler içerisindeki üretim payı artmıştır. Güneş enerjisinden elektrik üreten teknolojiler sadece düşük maliyetli olmalarından dolayı değil, aynı zamanda iklim değişikliği ile mücadeleye ve sürdürülebilir kalkınma hedeflerine katkılarından dolayı da tercih edilmektedir. Bu çerçevede; bu çalışmanın amacı, İstanbul'da bulunan bir yerleşkenin elektrik talebini karşılayacak, güneş enerjisini kaynak olarak kullanan fotovoltaik (FV) modüllerden oluşan bir sistemin tekno-ekonomik ve çevresel yönlerini incelemektir. Milli Savunma Üniversitesi Deniz Harp Okulu'nun toplam güneş potansiyeli; yerleşkedeki FV modüllerin çatıdaki kullanılabilir alanına, çatının kullanılabilir birim alanına, verime, inventör verimine ve FV dizini üzerindeki sıcaklık etkisine bağlı olarak hesaplanmıştır. Önerilen çatı tip FV sisteminin potansiyeli, modifiye edilmiş bir hesaplama yöntemi ile belirlenmiş ve daha sonra önerilen FV sisteminin fizibilitesi RETScreen simülasyon aracı tarafından geliştirilmiştir. Sonuç olarak, önerilen sistemin dört sene geri ödeme süresi sonunda pozitif nakit akışına ulaştığı ve öngörülen 25 yıllık proje ömrünün devamında da kâr durumunu devam ettirdiği, toplam sera gazı salımında %93 oranında azaltım sağlayarak 721.1 ton ham petrol kullanımından tasarruf sağlayacağı hesaplanmış ve Deniz Harp Okulu yerleşkesi için maliyetetkin ve çevre dostu bir uygulama olduğu değerlendirilmiştir.

“…A fraction order structure comprises by a fractional differential or an integral equation, and systems covering few equations, has been deliberate in engineering and physical appliances, for example active control, signal processing, linear and nonlinear response controller. The generally utilized approaches have been anticipated for numerical assessment of fraction derivatives by Riemann-Lioville and Grunwald-Letnikov definition [8,9]. It reflect a continuous function f(t), where its α th order derivative can be conveyed in reference [14].…”

“…This FOINC provides a dynamic mathematical model to adjust the PV array voltage towards the maximum power point. In Yu-Chi Wu et.al [9], suggests a three point weighting method that incorporates midpoint tracking to improve the limitation of the P&O and to enhance the efficiency of the three-point weighting method. It was establish that the proposed method tracked better than the three-point-weighting method, and it was capable of improving the deficiency of P&O method that has difficulty to track from the open-circuit voltage as well as enhancing the precision of the three-point-weighting method in the case of zero-weight.…”

This research suggests maximum power point tracking (MPPT) for the solar photovoltaic (PV) power scheme using a new constant voltage (CV) fractional order incremental conductance (FOINC) algorithm. The PV panel has low transformation efficiency and power output of PV panel depends on the change in weather conditions. Possible extracting power can be raised to a battery load utilizing a MPPT algorithm. Among all the MPPT strategies, the incremental conductance (INC) algorithm is mostly employed due to easy implementation, less fluctuations and faster tracking, which is not only has the merits of INC, fractional order can deliver a dynamic mathematical modelling to define non-linear physiognomies. CV-FOINC variation as dynamic variable is exploited to regulate the PV power toward the peak operating point. For a lesser scale photovoltaic conversion scheme, the suggested technique is validated by simulation with dissimilar operating conditions. Contributions are made in numerous aspects of the entire system, including new control algorithm design, system simulation, converter design, programming into simulation environment and experimental setup. The results confirm that the small tracking period and practicality in tracking of photovoltaic array.

“…The traditional chaos search is blindness; that is, it is difficult to determine the search times which are related to the complexity of objective function and the size of optimization space. So, it cannot guarantee the quality of search [26,27]. In order to improve MPPT precision and speed in PV system, in this paper, the process of chaos optimization search was divided into two stages: the rough search based on the first carrier process and the refine search based on the secondary carrier.…”

In order to deliver the maximum available power to the load under the condition of varying solar irradiation and environment temperature, maximum power point tracking (MPPT) technologies have been used widely in PV systems. Among all the MPPT schemes, the chaos method is one of the hot topics in recent years. In this paper, a novel two-stage chaos optimization method is presented which can make search faster and more effective. In the process of proposed chaos search, the improved logistic mapping with the better ergodic is used as the first carrier process. After finding the current optimal solution in a certain guarantee, the power function carrier as the secondary carrier process is used to reduce the search space of optimized variables and eventually find the maximum power point. Comparing with the traditional chaos search method, the proposed method can track the change quickly and accurately and also has better optimization results. The proposed method provides a new efficient way to track the maximum power point of PV array.
