Transient Stability Analysis of Power Systems with Energy Storage

Power systems can effectively damp power system oscillations through appropriate management of real or reactive power. This thesis addresses some problems in power system stability with and without energy storage.A power system model with energy storage is used to analyze the influence of three-phase faults on the transient stability of the systems using simulation to determine the Critical Clearing Time (CCT) using the following approach:(1) Prefault Period: Solve the power flow equation to obtain initial values.(2) Fault Period: With and without energy storage, use SMIB (single machine infinite bus) power system model with constant impedance load to determine how CCT (critical clearing time), real and reactive power change during transients. Dynamic and algebraic power flow equations (DAE) are solved simultaneously.(3) Postfault Period: Solve DAEs to determine system response.Simulation results show how energy storage affects CCT and real and reactive power supplied to the load during disturbances such as faults and changes in load.
