VOLTAGE STABILITY ANALYSIS OF NIGERIAN POWER SYSTEM USING DISTRIBUTED GENERATION

Accessing the impact of Distributed Generation on voltage control, inertia constants, power quality, fault current levels, protection system, etc. In Nigeria power system has not been studied critically with necessarytechnical actions taken to remedy all these factors (constraints). Their effects on power system stability were analysed using Port Harcourt transmission and distribution networks as a case study. ETAP was used inthe modeling of the power network system with its fault analysed. The impact of distributed generation on faults on the system was also analysed and the results showed that the addition of Distributed Generation in thedistribution network, the voltage profile of the system improved. The voltage profile of the bus that is nearer the Distribution Generation location was positively affected more than other locations in the network.
