This project analyzes load flow, voltage profile, and power losses for an industrial network integrated with both conventional (generator) and renewable (wind turbine) sources. The analysis is performed using ETAP 19.0.1C with adaptive Newton-Raphson load flow method for accurate steady-state performance evaluation.
