Improvement of Electrical Power Load Demand and Stability in Electrical Power System with Incorporation of Wind Power Generation

Abstract

Nowadays, the penetration level of wind generation in power system is one of the most evolving among renewable generation (solar and hydro generation) with a least cost of installation to support the power system expansion planning. Thus, this study aimed to improve the Nigerian power system stability and meet the load demand from customers during contingency with application of wind power generators. The new generation location was obtained by converting one of the load buses on Nigerian 31-bus power system to generator bus and a new generator admittance matrix using Y bus matrix was formed. Swing equation was employed and the behavior of generator during contingency was determined. Then, the L-VSI for each new addition generation was obtained and used to optimally identify new location for the placement of the wind generator in the power system. Simulation was done in MATLAB R2023a. The generator damping ratio, total active power losses and total cost of the generator were determined. It was revealed that the result verified the accuracy of effective placement of wind generator in the power system to meet the load growth
