VOLTAGE STABILITY ENHANCEMENT BY OPTIMAL SIZING AND SITING OF STATIC SYNCHRONOUS COMPENSATOR USING DRAGONFLY ALGORITHM

J Abubakar*, Y. Jibril, Boyi Jimoh

Ever- increasing demand of electric power makes transmission networks operate outside their voltage stability limits. To meet with the demand, the networks have to be improved, which may be difficult due to economic, environmental impact and implementation period. Therefore, Flexible Alternating Current Transmission Systems (FACTS) devices are employed to achieve proper utilization of existing tra...

A Study on State Estimation of Synchronous Generator using an Improved Unscented Kalman Filter Algorithm

Yahaya Ismail*, B. Jimoh, Adamu Abubakar Sa’idu

An enhanced Unscented Kalman Filter (UKF) technique for synchronous generator state estimation is presented in this study. The suggested approach overcomes the drawbacks of conventional UKF in managing noise and nonlinearities in power systems. Comparative analysis and validation are made on the tracking performance of Normal Ukf and Improved Ukf (SR-Ukf) algorithms and the simulation results show...

FREE SET POINT TRACKING AND DISTURBANCE REJECTION OF BINARY DISTILLATION COLUMN USING MODEL PREDICTIVE CONTROL

A. T. Salawudeen*, Zaharaddeen Haruna, B. Yahaya, I. F. Egbujo, U. R. Bello, A. Y. Zubairu, I. Nwokocha, I. Hamisu

Off set free set point tracking is a challenging problem in distillation column control. This isusually due to the multivariable nature of the distillation column and hence the interactionbetween the loops. This study designed a model predictive controller using MATLAB andSimulink for a Lubyen Vinate Distillation Column. The results show that the model predictivecontroller performs an off set free...

Development of an Optimal On-Load Tap-Changing Scheme for a Transformer to Improve Power Quality

Ahmad Ibrahim*, Boyi Jimoh, Adamu Abubakar Sa’idu

Voltage instability remains a major operational challenge in large-scale transmission networks, particularly in developing power systems with increasing load demand. This paper proposes a coordinated on-load tap changer (OLTC) control strategy based on a Hybrid Particle Swarm Optimization–Grey Wolf Optimization (HPSOGWO) algorithm to enhance voltage stability and power quality. The proposed approa...

Development of Improved Particle Swarm Optimization Algorithm Based on Success Rate for Optimal Placement of DG on Distribution Network

H. Yusuf*, A.S. Abubakar, Y. Jibril, J. Abubakar

The increase in load demand of distribution networks, made the role of distribution systems (DSs) difficult for the power utilities. However, thoughtful planning for supplementary power reimbursement are necessary on DSs for power loss and voltage deviation minimization which is done by optimization techniques. An Improved Particle Swarm Optimization algorithm Based on Success Rate (IPSO-SR) was i...

Development of Energy Management System for Microgrid System Considering Demand Response Program for Clean and Economic Operation

Obiabo Okeme*, B. Jimoh, Abdullahi Bala Kunya, Abah David Enemali

Micro-grids are small-scale localized energy systems operating independently or in conjunction with the main power grid. A micro-grid system (MGS) is made up of various energy sources like solar panels, wind turbines, fuel cells, along with storage units, control mechanisms, and a network of radial load feeders, all designed to enhance the economic efficiency of the micro-grid system. A fundamenta...

APPLICATION OF PARTICLE SWARM OPTIMIZATION AND SIMULATED ANNEALING TECHNIQUES FOR OPTIMAL LOCATION AND SIZING OF DISTRIBUTED GENERATORS

S. M. Lawan*, W. A. W. Z. Abidin, T. Masri, S. J. Kawu

Distributed Generators (DGs) are generators that produce electrical power from quite a fewmodest energy resources. Some could be referred to as on-site generation, dispersedgeneration, embedded generation, decentralized generation or distributed energy. TheseDGs are located in metropolitan locations if you want to minimize the losses in transmittingthe energy. In order to identify the size of the ...

Optimized PID Based Load Frequency Control of a Hybrid Microgrid

S. M. Aminu*, Y. Jibril, Abubakar Abdulkarim, A.S. Abubakar

This research presents the development of an optimized PID based load frequency control of a hybrid microgrid. The micro-grid (MG) concept allows the renewable energy sources to operate in both synchronized grid and islanded/stand-alone mode. These modes of operations of the MG have made it smart, hence require intelligent coordinated control strategies. The existing control strategies of the MG s...
