The results of the Newton-Raphson load-flow solution in Power World Simulator and MATLAB platform obtained for each of the two bus identification types revealed the convergence failure in one identification model numbering type.
In this study, analysis is carried out on the failure to convergence the result of load-flow as obtained for the 28-bus power system of the Nigerian 330-kV network using two different bus identification numbering sequence types. All these studies aimed at increasing the efficiency of the network and reduce real and reactive power losses. The Nigerian 330-kV transmission lines used in this study are radial and are overloaded thus, it has been subjected to numerous studies covering many areas as to how improvements can be made. The simulation of the load-flow analysis is carried out using the software of Power World Simulator and MATLAB, while verification of power losses is simulated with only MATLAB software.
The objectives of this research include the Newton-Raphson-based load-flow analysis and verification of power losses. This paper explains the effects of bus numbering using a load-flow study to investigate the Nigerian 330 kV radial transmission networks.
