Abstract

In recent times, adverse environmental changes and the gradual reduction in fossil fuel deposits is making integration of renewable  energy secure global attention. This paper therefore investigates the effect of high penetration of wind power on power loss and voltage  profile of 52-bus, 330kV Nigerian grid. Modeling and simulation of the study were successfully done using the Continuation Power Flow  method and Power System Analysis Toolbox in the Matrix Laboratory environment. The Ant Colony Optimization (ACO) technique codes  were used to determine the best sites and sizes of Permanent Magnet Synchronous-based Wind Turbine Generators (PMS-WTGs) on the  grid as nonoptimal placement and size of PMS-WTGs will result into active power losses and poor voltage profile. The ACO and power  flow analysis indicated two load buses, Aladja bus and Yola bus as best sites for PMS-WTGs with optimal sizes of 100MW and 197MW  respectively. The result shows a decrease in the system's active (42.1%) and reactive (43.9%) power losses while heightening voltage magnitudes of critical buses to statutory values and enhancing the grid power quality. The overall results indicate that integrating 297MW  PMS-WTGs improves voltage stability and power loss reduction by maximizing system loadability and reducing line losses.
