Power System Dynamics and Simulation

This chapter discusses power system dynamics and simulation using the electromechanical model for generators and the constant impedance model for loads. It shows how generators and loads can be connected into the static power network to form a dynamic system. The chapter presents the impact of faults on power system stability by simulating the resulting power system dynamics. It discusses fault‐on and post‐fault electrical power computation for the single‐machine infinite‐bus system. The chapter analyses dynamic simulation and uses the electromechanical model of synchronous machines to illustrate the simulation of power systems subject to disturbance conditions. The Euler method requires one evaluation of vector at each integration step, and is straightforward to implement. The chapter also discusses several integration methods for numerically computing the time response of such dynamic power systems to disturbances.
