Load flow analysis is a critical component of power system analysis, as it allows engineers to determine the steady-state operating conditions of an electrical system. Traditional methods of load flow analysis involve solving a set of nonlinear algebraic equations, which can be time-consuming and prone to errors. In this study, the development of algorithmic power flow equations for load flow analysis in ETAP software was aimed to provide a more efficient and accurate method for analyzing power flow in electrical systems in various power zones in Uyo, Akwa Ibom State, Nigeria. The traditional methods of load flow analysis are often complex and time-consuming, requiring manual calculations and iterations to converge on a solution. This can be a barrier to efficient power system analysis, particularly in large and complex electrical systems. The need for a more efficient and accurate method for load flow analysis has led to the development of algorithmic power flow equations in the ETAP software. The methodology of this study involved the development of algorithmic power flow equations based on the principles of power flow analysis. These equations were then implemented in the ETAP software, allowing the performance load flow analysis with greater efficiency and accuracy. The algorithmic equations were designed to solve the power flow equations iteratively, converging on a solution that accurately represents the steady-state operating conditions of the electrical system. The software revealed a maximum efficiency of 97.66% for the various zones such as Faith Street S/S3, Mask S/S, NEPA Road S/S2, Peter Uboh S/S4, PORT Harcourt Street S/S, Silas Udo S/S and Winners Chapel 47. In all these zones, core losses of 0.375, 0.062, 0.375, 0.625, 0.625, 0.062 and 0.375 were obtained. It was observed that in rural areas with lower electrical demand and less industrial activity, power transformers might have a longer replacement time and lower full-load current. Maximum rated power of 500. The findings demonstrate the effectiveness of the ETAP algorithmic power flow equations in calculating power flow in electrical systems. The algorithm is able to converge on a solution quickly and efficiently, providing a reliable tool for load flow analysis.
