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 DGs gives additional fault current contribution t...

MULTIPLE MONTE CARLO SIMULATED HIDDEN MARKOV MODEL FOR FUZZY TIME SERIES FORECASTING

A. T. Salawudeen*, A. Nurudeen, S. Garba, S. U. Hussein, M. L. Imam, I. F. Egbujo, B. Yahaya

This paper presents a Monte Carlo based Hidden Markov Model (HMM) for fuzzy timeseries forecasting. To make the nature of conjecture and randomness of forecasting morerealistic, the Monte Carlo method with different simulation size is adopted to estimate theforecasting outcome. To address the insufficiency in data associated with the HMM model,we adopted a method called smoothing. A number of simu...

Integrated Economic and Emission Dispatch of Hybrid Thermal-Photovoltaic Generation

I. Abdullahi*, U. Musa, B. Musa, A. Aliyu, Abdullahi Bala Kunya, S.A. Alkali, S. Awaisu

Due to the increasing demand for qualitative electric energy at a competitive price and reduced environmental deterioration, electric power generation systems should be optimally dispatched. In this paper, the Integrated Economic and Emission Dispatch (IEED) of hybrid thermal-photovoltaic power plants using Bat (Chiroptera) Inspired Algorithm (BIA) is presented. The IEED technique entails determin...

DECOMPOSITION APPROACH TO THE NEWTON- RAPHSON BASED HYDRO-THERMAL OPTIMAL POWER FLOW SOLUTION

Muyideen Olalekan Lawal*, OlusolaAderibigbe Komolafe

This paper presents a decomposition approach to the hydro-thermal optimal power flow problem to address the mathematical difficulty due to large number of variables and constraints associated with the problem. The decomposition of the problem is achieved by dividing the optimization period under consideration into hourly time intervals. The optimization problem for each time interval is first solv...

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 battery SOC for the hybrid electric vehicles (HEV). I...

SURF-FAST BASED PARTICLE FILTER TRACKING OF ARAPAIMA GIGAS

F. S. Bala*, A. A. Shafie, U. U. Bello

Invasive Alien Species (IAS) of fish has recently become issue of concern, due to their adverse ecological effect, as well as potential risk and danger to humans. Method of containment mostly employed to invasive fish without harming indigenous fish species would involve direct human effort. The involvement of humans in physical and direct containment of invasive fish species can be very tedious, ...

CONTROL OF LOAD FREQUENCY IN INTERCONNECTED POWER SYSTEMS: A COMPARATIVE ANALYSIS OF PID AND PI CONTROLLERS

Mustapha Muhammad M*, Jafaru Usman, Armaya’u Sarki, Bashir Baba Abba, M. Abdulkadir

This paper presents load frequency control of two area interconnected power system using PID controller and PI controller. The main target of load frequency control is to maintain good tracking of load demand and zero steady state errors for frequency deviation in a multi-area power system. This help to maintain a balance of energy and frequency of power generation system and enable proper power e...
