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 strat...

APPLICATION OF WHALE OPTIMIZATION ALGORITHM (WOA) FOR DISTRIBUTION NETWORK RECONFIGURATION SCHEME FOR POWER QUALITY IMPROVEMENT

A Bukar^*, Gbenga Abidemi Olarinoye, Y. Jibril

Electrical power distribution networks (DN) are usually designed and operated in a radial configuration, but their topology, especially when highly loaded, is often meshed in order to improve system reliability and quality of the supply. This makes it feasible to alter the network topology after an outage to restore the service to affected areas. I...

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 Optimizati...

DEVELOPMENT OF AN IMPROVEDARTIFICIAL BEE COLONY BASEDCOORDINATION SCHEME FOR DIRECTIONAL OVERCURRENT RELAY IN DISTRIBUTION NETWORKS

A. J Akinbobola^*, Boyi Jimoh, Y. Jibril, C.O Okonkwo, K.O. Iyapo

A modified Directional Over-Current Relay (DOCR) operational time characteristic equation has been developed by introducing two new parameters (load current ratio and fault/load voltage ratio) into the conventional operational time characteristic equation to ensure flexibility while still retaining the necessary property of the original equation. A...

C.O Okonkwo^*, B. Jimoh, Y. Jibril, A. J Akinbobola, E.S Onyema

An Improved Binary Coded Genetic Algorithm for optimal Phasor Measurement Unit (PMU) deployment. A new PMU deployment optimizer was developed, and integrated into the conventional binary coded genetic algorithm (BCGA), to form an improved binary coded genetic algorithm (IBCGA), with high rate of convergence. This is applied for the optimal deployme...

DEVELOPMENT OF AN OPTIMIZED DUAL RELAY SETTING COORDINATION SCHEME FOR DISTRIBUTION NETWORK WITH DISTRIBUTED GENERATION

Babatunde Lambo^*, Y. Jibril, Boyi Jimoh, Adamu Abubakar Sa’idu

In Distributed Generation systems (DG), the fault current through a relay in forward direction is mostly higher than in the reverse direction. Thus, it is desirable to have dual setting directional over current relay (DOCR) which can operate for both forward and reverse direction of fault current with two independent relay settings. The presence of...

PLUG IN HYBRID ELECTRIC VEHICLE ENERGY MANAGEMENT DESIGN USING DISCRETE BAT ALGORITHM

S. B Kamal^*, Patrick Ubeh Okorie, Y. Jibril, Adamu Abubakar Sa’idu

This paper presents an energy management for improved battery state of charge (SOC) in Plug-In-Hybrid Electric Vehicle (PHEV). Due to the on-board charging requirement of PHEV engine and generator a means for optimal charging of the battery SOC becomes necessary. This requirement is viewed as an optimal solution of maintaining the best possible bat...

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 empl...
