Bu çalışmada, Hibrit Yenilenebilr Enerji Siatemleri optimizasyonunda kullanılmak üzere bu alanda en sık kullanılan HOMER programının olumsuz yönlerini bertaraf eden metasezgisel Parçacık Sürü Optimizasyonu tabanlı optimizasyon aracı tasarımı yapılmıştır. Güvenilirliğinin ortaya konması nedeniyle aynı yükü beslemek için gerekli hibrit sistem, hem geliştirilen araç ile hemde HOMER optimizasyon yazılımı ile optimize edilerek sonuçlar karşılaştırılmıştır. İşlem hızı bakımından yapılan karşılaştırmada aynı sistemi optimize etmede, HOMER yazılımının 936 saniyede elde etmiş olduğu sonucu 17 saniyede elde ederek tasarlanan sistemin daha hızlı sonuca ulaştığı görülmüştür. Ekonomik yönden yapılan karşılaştırmada ise iki ayrı aracın yapmış olduğu optimizasyon sonucunda; Enerji maliyetinde 1.737 % , Toplam Net Bugün ki Maliyette 0.85 % ve Başlangıç Sermayesinde ise 1.895 % lik fark bulunmakta olup sonuçlar arasında önemli bir farkın bulunmadığı gözlenmiştir. Elektriksel sonuçların kıyasında ise Beslenen yüklerde 0.031 %, Beslenemeyen yüklerde 1.071 % lik fark çıkmış olup elektriksel anlamda da sonuçların güvenilirliği ortaya konmuştur. Sonuçlar bu alandaki detaylı optimizasyon çalışmaları için umut vericidir. Ayrıca HOMER yazılımının sunmakta olduğu, ekonomik ve elektriksel detaylar, gerçeği temsil eden özgün bir sevk stratejisi sayesinde tasarlanan araç ile de kullanıcıya sunulmaktadır. Güvenilirlik parametresi olarak HOMER yazılımının içerdiği fakat daha önce metasezgisel algoritmalarla yapılan optimizasyon süreçlerinde hiç kullanılmamış olan kapasite eksikliği parametresi kullanılmaktadır. Kapasite eksikliği parametresi ilk defa metasezgisel algoritma ile yenilenebilir enerji kaynaklarının optimizasyonunda kullanılmıştır. Maliyet fonksiyonu olarak Enerji Maliyeti kullanılmıştır. Kısacası HOMER programına alternatif çok daha hızlı sonuca ulaşabilen ve HOMER programındaki hassasiyet, hantallık ve zorlu arama uzayı oluşturma süreçlerini bertaraf eden özgün, güvenilir bir optimizasyon aracı tasarlanmıştır. Bu araç sayesinde ayrıca, vekil modelleri, makine öğrenmesi veya derin öğrenme tabanlı optimizasyon sistemlerini eğitmek için gerekli optimizasyon çıktıları çok hızlı bir şekilde elde edilerek fazla sayıda veri üretilmesi kolaylaşacaktır.

The integration of renewable energy sources, such as wind and solar, into co-located hybrid power plants (HPPs) has gained significant attention as an innovative solution to address the intermittency and variability inherent in renewable systems among plant developers because of advancements in technology, economies of scale, and government policies. However, it is essential to examine different challenges and aspects during the development of a major work on large-scale hybrid plants. This includes the need for optimization, sizing, energy management, and a control strategy. Hence, this research offers a thorough examination of the present state of co-located utility-scale wind–solar-based HPPs, with a specific emphasis on the problems related to their sizing, optimization, and energy management and control strategies. The authors developed a review approach that includes compiling a database of articles, formulating inclusion and exclusion criteria, and conducting comprehensive analyses. This review highlights the limited number of peer-reviewed studies on utility-scale HPPs, indicating the need for further research, particularly in comparative studies. The integration of machine learning, artificial intelligence, and advanced optimization algorithms for real-time decision-making is highlighted as a potential avenue for addressing complex energy management challenges. The insights provided in this manuscript will be valuable for researchers aiming to further explore HPPs, contributing to the development of a cleaner, economically viable, efficient, and reliable power system.

“…Global action toward increasing clean energy technologies is growing due to the role they play in energy security and climate change mitigation, as well as their perception as the most economically viable option (Iweh et al, 2021). As the perception is rising in the African continent, there are potentials to leapfrog the conventional centralized power grid model of energy supply to a more sustainable grid powered by renewables (Iweh et al, 2022a) since the uptake of clean energy technologies comes with extra benefits for economic productivity and socioeconomic development (Sen and Ganguly, 2017;Singh and Nyuur, 2019). Renewable energy makes up a small share of overall global primary energy consumption, contributing ∼12% in 2020 (IRENA, 2021).…”

The Intergovernmental Panel on Climate Change (IPCC) 2021 report has noted the perceived rise in severe weather phenomena such as heat radiations, hurricanes, flooding, and droughts and the rising scientific evidence attributing these events to anthropogenic sources of climate change. Cameroon as a nation is equally exposed to these climate vulnerabilities, and contributing to global climate efforts is imperative. She has earmarked the integration of 25% renewables in its electricity production mix and a 32% emission reduction, all as part of her commitment to global climate action. The fresh commitments coupled with a rapidly growing power demand have paved the way for a revolutionized approach to electricity generation in Cameroon. However, the imminent changes, as well as their implications, remain uncertain. This study explores how these emission reduction targets can be achieved through the adoption of a more sustainable power transition, which provides realistic solutions for emission reduction, escaping high carbon pathways. The assessment of the level at which long-term electricity generation scenarios in Cameroon could be renewable energy intensive was done using the Low Emissions Analysis Platform (LEAP) tool following a backcasting approach. The study noted that there is an implementation gap between earmarked policy ambitions and existing measures. The study recommended several opportunities in aspects, such as suitable share of technologies, administrative reforms, and required adjustments within the Nationally Determined Contributions (NDCs), which the government could exploit in the electricity sector to sail across the challenging trade-offs needed to become a sustainable economy in a carbon-constrained world. It equally examines actions that could help close the gap between earmarked policy ambitions and existing pathways and proposes cost-effective methods that were identified as priorities.
