Despite this growth, a critical gap exists – a genuine operational performance assessment specific to the Maldives. This article pioneers such an evaluation, focusing on a 6.6 kWp rooftop PV system at STECO's bus station in K. Male'. Utilizing

Conditional monitoring and fault detection of wind turbines based on Kolmogorov–Smirnov non-parametric test Energy Rep. (IF 5.2) Pub Date : 2024-02-20 Olayinka S. Ohunakin, Emerald U. Henry, Olaniran J. Matthew, Victor U. Ezekiel, Damola S. Adelekan, Ayodele T. Oyeniran
This research presents a new method for conditional monitoring based on the wind turbine power curve. The Kolmogorov-Smirnov (K-S) distribution test is employed in the assessment of turbine data and the detection of abnormality (faults) in wind turbines. The process begins with anomaly detection and filtration of faulty SCADA data by a quantile-based filtration approach. Suitable data comprising wind

Maximizing power transfer in transmission networks with TCPS: A non-linear programming-genetic algorithm approach Energy Rep. (IF 5.2) Pub Date : 2024-02-20 Syed Abdullah-Al-Nahid, Tafsir Ahmed Khan, Md. Abu Taseen, Silvia Tasnim, Tareq Aziz, Taskin Jamal
This study presents an advanced methodology for maximizing the performance of Thyristor-Controlled Phase Shifters (TCPS) in order to enhance power transfer capacity within transmission networks. As a flexible AC transmission system (FACTS) device, TCPS plays a crucial role in providing dynamic control over bus voltage and angle, thereby improving the power system overall operational efficiency. The

Towards sustainable electricity generation: Evaluating carbon footprint in waste-to-energy plants for environmental mitigation in Iran Energy Rep. (IF 5.2) Pub Date : 2024-02-20 Kiana Rouhi, Majid Shafiepour Motlagh, Fatemeh Dalir, Javier Perez, Abooali Golzary
The environmental impacts of municipal solid waste have become a critical issue in Iran due to rising waste generation and limited waste treatment methods. From a global warming perspective, in 2018, Iran was the seventh-highest greenhouse gas emitter in the world. An implementation should demonstrate that it is possible to estimate the environmental impact of climate change. A simple carbon footprint
