Cost – Power Modeling of Kainji Hydro Scheme Units Using MATLAB

Abstract

Mathematical Models which describe the behavior of the units in Kainji hydro scheme in terms of the cost of generation as a function of power generated were developed in this work. Data including monthly operating costs in Naira (), corresponding monthly power in Megawatt (MW) and energy in Megawatt hour (MWh) contributed by each unit for the year 2008, due to data availability, was collected from the power plant. Using MATLAB environment, the objective function of each unit was modeled in terms of generation cost (/hr) as a function of power (MW) generated per unit.
