Modeling and simulation of electrical power flow in a brewery: An approach for optimized sizing and energy loss minimization

In the context of designing a new industrial brewery, this study introduces a comparative approach between the classical analytical method and numerical simulation-based modeling for the purpose of electrical network sizing and optimization. The primary objective is to evaluate the extent to which power flow simulation enables more accurate equipment sizing (particularly the main transformer) and contributes to minimizing energy losses while enhancing the stability of the internal electrical grid. Based on a representative single-line diagram, a digital model is developed using the ETAP software suite. The results demonstrate that simulation not only improves the precision of sizing but also enables efficient localization of voltage drops and overload points. The proposed adjustments lead to enhanced overall energy performance and operational reliability.
