Load flow studies form the basis for the steady-state analysis of power systems and are performed for a wide range of applications from planning to operations. The studies are typically conducted using computer software packages such as PSSE, DIgSILENT PowerFactory, ETAP, PowerWorld and SKM Power*Tools. The load flow (or power […]
