Firefly Algorithm-Based Optimal Deployment of Unified Power Quality Conditioner for Loss Minimization and Voltage Stability Enhancement in Distribution Networks

Musa Mustapha^*, Mustapha Kunduli, Babangida Modu, Modu Abbagana, Modu Ali Gana, Musa Baba Lawan

The increasing penetration of nonlinear loads and distributed generation (DG) in distribution networks poses significant challenges to voltage regulation and power loss minimization. Although Unified Power Quality Conditioner (UPQC), has proven effective in enhancing power quality and system stability, determining its optimal location and size remains a complex optimization problem. This study exa...

Development of Optimal Electricity Management Systems to Minimize Resources and Losses using Particle Swarm Optimization Techniques: A Case Study for UDUS

A. U,Lawan^*

Hybrid energy systems (HESs), have played an important role as clean and efficient source of electricity generation. HESs are often formulated as an optimization problem which is solved mostly using metaheuristics techniques. The conventional objective function is based on levelized cost of energy (LCOE), the lowest loss of power supply probability (LPSP), and the maximum renewable factor (REF) as...

Subthreshold Signal Enhancement in a Space-Dependent Damped Van der Pol-Duffing Oscillator via Vibrational Resonance

Usama Bello Ibrahim^*, Hamza Mustapha, Mannir Ahmad, Adamu Abubakar Sa’idu

This paper presents a numerical study of a subthreshold signal enhancement in a Van der Pol-Duffing oscillator, via the phenomenon of vibrational resonance. The oscillator describes a particle motion in a bistable periodic potential, influenced by space-dependent damping and excited by an external bichromatic excitation. Temporal and spectral analyses approaches were employed to analyze the system...

Assessment of Wind and Solar Energy Potential at ADUSTECH-Wudil for Hybrid Electricity Generation Using Weibull Distribution and Samani Model

Mamunu Mustapha^*, Aminu Tijjani, Usman Aliyu Magaji, Sani Salisu, O. O. Mohammed, Abah David Enemali

Intermittent nature of electricity supply in Nigeria is not only affecting social-economic sector, also educational sector. It affects activities such as lecture presentation, laboratory practical etc. Also, the inconsistency in the cost of fuel is making it difficult to conduct some laboratory practical in some Nigerian Universities. This work analyzed the wind and solar data of Aliko Dangote Uni...

ASSESSMENT OF PID-BASED CONTROL OF SERVOACTUATORS FOR FLIGHT REGULATION OF SMALL UNMANNED AERIAL VEHICLES

Mahmud S. Zango, Ameer Mohammed^*, Jamilu U. Yahaya, Khalid K Dandago, Muhammad I Muhammad, Abdulbasit Hassan

Flight control systems for unmanned aerial vehicles (UAVs) are responsible for maintaining safe flight – they are required to be reliable and robust. Flight regulation is achieved by controlling servomotors linked to flight control surfaces – ailerons, rudder, elevators and flaps. The most important parameters in servomotor control are position and speed. Hence, this work performed an assessment o...

INTERNAL MODEL CONTROL PERFORMANCE EVALUATION IN NONLINEAR COUPLED TANK SYSTEM

I. A. Shehu^*, M. Mohammed, Abubakar Abdulkarim, M. Auwal Shehu

Most industrial process control systems are associated with non-linearity behaviour.Control of such industrial process system is a challenging task according to the degree ofnon-linearity of the system. A typical process control that represent part of such complexindustrial process is the principle used in Coupled Tank System (CTS) level control. Thispaper investigated the performance of Neural Ne...

DIPOLAR MAGNETIC FLUX LEAKAGES FOR PIPELINE RECTANGULAR DEFECT CHARACTERIZATION: ANALYTIC APPROACH

L. U. Daura^*, A. Dan-Isa, S. A. Babale

Magnetic Flux Leakages (MFL) find its application in non-invasive of Non-Destructive Testing and Evaluation (NDT&E) to detect and characterizeddefect in pipelines made from ferromagnetic materials. Various improvementsof MFL models have been investigated for defect quantification but still couldnot achieve higher precision due to technical errors. We, therefore, proposemodels that minimize the err...

REVIEW ON METAHEURISTIC-BASED DECISION TREE INDUCTION

Ismaila Mahmud^*, Abubakar Abdulkarim, Sulaiman Haruna Sulaiman, Umar Musa

Decision tree is one of the well-known machine learning algorithms which remain popular due its simple implementation and ease of understanding. Existing techniques used in inducing decision tree have shown that they suffer data overfitting which leads to producing small size of decision tree model. To address the drawback and improve the performance of the algorithm, hybridization of metaheuristi...

Development of Optimized Maximum PowerPoint Tracking Scheme for A Partially Shaded Photovoltaic System

M. Aderinola^*, A.S. Abubakar, Abdullahi Bala Kunya

Solar energy harnessed through photovoltaic (PV) technology plays a pivotal role in generating electrical energy. Maximizing the power output of solar modules requires optimal solar radiation. However challenges arise due to obstacles such as stationary objects, building, tree leaves and winds, which can result in the presence of multiple points of maximum power on the PV curve. This problem neces...
