.EVALUATION OF THE IMPACT OF POWER SECTOR REFORM ON THE NIGERIA POWER SYSTEM TRANSIENT STABILITY

This paper evaluates the impact of power sector reform on the Nigeria 330KV Grid System’s response to large disturbances. The power sector reform on-going in Nigeria has the prospect of impacting positively to the transient stability status of the Nigeria Power system owing to massive investment in generation, transmission and distribution segments of the power sector. Evaluation of the transient stability status of pre-reform 8-plants, 26-bus system and projected 16-plants, 49-bus system under superimposed large disturbances were conducted using MATLAB program. The areas of instability threats in the existing network was highlighted, while the expected level of reform-induced improvement were identified; and recommendations made for further improvement on the system stability.
