Systems engineering perspective on power transmission for Nigeria

PI: Adegoke Melodi ( or with co-PI Olatubosun Olabode, The Federal University of Technology, Akure
U.S. Partner: Kevin Tomsovic, University of Tennessee
Project Dates: September 2014 - August 2018

The aim of this project is to develop an algorithmic model for planning transmission expansion or development in order to achieve acceptable reliability of transmission and maximize cost-benefit ratio of transmission operations under the growing deregulated operating environment of Nigeria and the probabilistic factors affecting power transmission-demand relationship. It is expected that the model would be applicable to power distribution as well. Primarily, the model would enable a dynamic planning process for providing optimal plan options, applicable for implementing transmission installations and operations that will prevent recurrence of historically unreliable transmission problems in Nigeria under a State-regulated environment and ensure sustainable service for the Transmission Company of Nigeria (TCN) under deregulated conditions. The novel concept in this project includes the application of a value base reliability approach to transmission expansion planning (TEP) of the Nigerian power transmission network, which will be embedded in a developed multi-stage and multi-objective optimization algorithm for the transmission planning. This concept will use a state-of-the-art optimization procedure and a new congestion index. Further, the proposal will provide guidelines for future TEP to be used by TCN planning engineers.

In summary, the proposal is expected to provide an optimal value-based reliability TEP determination framework, which considers prevailing power market dynamism, for assisting system development in deregulated demand-supply condition; and typical optimal TEP solutions for the Nigeria transmission network  in the short and long terms.

The framework developed will restore value reliability and economically effective power transmission to the Nigerian future systems, in line with Power Africa objectives. Implementation of the proposal should provide opportunities for training male and female students at  the Federal University of Technology, Akure, in power systems planning research and improve on the research contributions and capacity of the investigators in providing solutions to African power development problems.

Further, the implementation of the proposal within the Federal University of Technology, Akure will assist in developing the university’s infrastructure and human capacity in power research.

Summary of Recent Activities

During this quarter ending March 2018, the focus was on the review of results obtained so far and continuation of research work on the project tasks. The PI and his team are trying to factor in other possible variants of system capacity expansion. Some new students have been admitted but yet to conclude on specific roles in the remaining work. Some emerging or identified problems are being assigned to train the new graduate students. They are deploying experience acquired so far in modern theory, data analytics and software to expand their training of new students in transmission expansion planning and power systems engineering in general. Some have presented proposal seminars on assigned tasks. The experience is impacting the training approach of new students in power systems engineering research, especially in the application of modern software and methodology. Lastly, the team is putting together a budget in view of planned stakeholder workshop for a date in July or August.

In the next 3 months they are planning to screen their workspace with aluminum panels to secure out equipment against noticed dust and pests; publish more papers; and present the two currently involved students in the PEER project for final defense of their projects, a prerequisite to completing their masters programs.
