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, D.E Abah

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...

INTERNAL MODEL CONTROL PERFORMANCE EVALUATION IN NONLINEAR COUPLED TANK SYSTEM

I. A. Shehu*, M. Mohammed, A. 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...

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

M. Aderinola*, A.S. Abubakar, A. B. 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...

TIME SERIES WIND SPED PREDICTION WITH ENERGY MAPPING USING HYBRID INTRINSIC MODE FUNCTION (IMF) AND EXTENDED INPUT NEURAL NETWORK (EINN)

S. M. Lawan*, W. A. W. Z. Abidin, T. Masri, F. A. Umari, A.Y. Abdullaahi, S. J. Kawu

Accurate and precise wind speed predictions are a prerequisite requirement that isnecessary before siting of wind turbines. The output power of wind energy system iscompletely depends on the behavior of wind speed; a small deviation of wind speed willlead to large energy losses. This paper presents a new technique for predicting the windspeed based on hybrid model Intrinsic Mode Function (IMF) and...

Comparative Analysis of Conventional Single and Hybrid Photovoltaic Solar Energy System for Off-Grid Rural Electrification

Umar Alhaji Adamu*, Oghenewvagaga Oghorada, Ismaila Mahmud, Mahmud Mustapha, Ibrahim Sabi’u, Ibrahim Bashir Shehu, Simon Wakawa

Renewable energy sources are essential around the globe in power generation with solar photovoltaic energy system as one of the major sources. Lack of access to affordable and reliable power in rural off-grid communities affects their wellbeing in terms of economic and social activities. In Nigeria, over 60% of Nigerian rural communities are not grid connected and lack access to affordable and rel...
