VOLTAGE STABILITY INVESTIGATION OF POWER SYSTEMS WITH GRID-CONNECTED WIND TURBINE GENERATORS: A CASE STUDY OF THE NIGERIAN DISTRIBUTION SYSTEM

📄 Project Abstract

Wind energy is one of the fastest growing technologies in energy generation industry nowadays. As wind energy is increasingly integrated into power systems, the stability of the existing power systems is becoming a concern and of utmost importance to the power system engineers and operators. The subject of voltage variation at the Point of Common Coupling (PCC) is very crucial to the consumers. This voltage variation is as a result of variable nature of wind turbine power output, which is a function of the wind speed. A load-flow analysis, therefore, needs to be carried-out to ascertain the effect on the test distribution grid with and without the connection of wind turbine generators. Only a small part of Lagos (test) Distribution system is considered in this research work. The purpose of carrying-out load-flow analysis is to evaluate the voltage at each bus, its phase angle and the total loss on the system. Due to high Resistance/Reactance (R/X) ratio of the distribution lines and th...
