Transient stability (TS) simulation is one of the most powerful tools to study and improve the behavior of power systems. In addition, new domains of research are using the TS to determine the optimal power flow after a disturbance. The TS is a division of the rotor angle stability that simulates and analyzes the dynamical behavior of synchronous machines before, during and after a disturbance. The most common pattern to study the transient stability is a time domain simulation (TDS). To this end, we formulate a set of algebraic differential equations (DAE) that simulate dynamical behavior of the machines connected to the power system. These equations are nonlinear and their solution requires the application of iterative numerical integration methods.
This project implements a TS program that includes detailed and classical models of synchronous machines. Similarly, for the simulation with the classical model, ten different integration methods using implicit and explicit integration with fix or variable integration steps were included. For the detailed model, two algorithms to solve the DAE system with simultaneous implicit and partitioned explicit methods were carried out. In addition, we tested how the program works in different cases: WECC three machines, New England ten machines, 17 machines and 50 machines. For each study case, the performance of each method in terms of accuracy and speed was analyzed.
This program aims to serve as a simulation tool in research requiring the use of a transient stability program.
