Steady State and Quasi-Dynamic Alternating Current Power Flow (ACPF) Simulation

Welcome to the first tutorial on power flow. This tutorial is designed to provide new users a strong foundation in their journey to becoming an expert user of SAInt. The ideas presented here will assist the user in becoming familiar with the operation of SAInt and the common workflow while using the software. This series of instructions will use the GUI to leverage SAInt to run steady-state and quasi-dynamic ACPF simulations. In SAInt these type of models are referred to as SteadyACPF and QuasiDynamicACPF scenarios.

The AC power flow simulation uses mathematical models to predict the behavior of electrical components, including voltage, current, and power flow between generators, transmission lines, transformers, and loads, under different operating conditions.

This series starts by explaining how to create an AC power flow model in the SAInt environment. The first step is creating a network file and adding lines and nodes to construct the system’s topology in the map window. The next step is to add external objects to the nodes, allowing the injection or extraction of energy at the node. After completing the network file, it’s time to create the scenario file to run a power flow simulation. This file includes scenario events and profiles. Events can control or limit the objects and constraints on the system, while profiles are used to model the dynamic behavior of different object parameters. The final step in the workflow is to execute the simulation.
