Abstract :

The authors have examined a simulation study on the application of distribution static compensator (DSTAT-COM) in a microgrid to solve power quality (PQ) problems. Integrating renewable energy sources (RES) to realise microgrids at distribution corridor further aggravates customer’s power quality, which is often defined asany deviation from the fundamental, of either voltage or frequency signal. Traditionally, the solution is sought through careful design of proportional-plus-integral (PI) controllers for DSTATCOM interfaced mi-crogrid network. The PI parameters would normally involve internal current and external voltage control loops, as well as the DC-link voltage regulator. In this paper, modeling and simulation ofDSTATCOM based 9MW wind turbine generators (WTG) representation of microgrid system is implemented in Simulink’s Sim-PowerSystems for solving two distinct PQ problems: that is, voltage sag and voltage swell. The results ob-tained conformed to the requirement of the IEEE Standard 519 of 1992.
