Abstract:

As a distribution power grid is subjected to a contingency such as fault, system frequency and voltage may be severely deteriorated and becomes harmonically. In addition, the concerns about stability issues grow with large fault occurring in the distribution power system. Distribution STATCOM (DSTATCOM) is nominated as a fast-response and robust device for mitigation of instability and oscillation problems. These capabilities of DSTATCOM can be improved by inclusion of relatively fastacting energy storage systems (ESS) such as Ultra Capacitor (UC). The aim of this paper is to investigate the application of DSTATCOM accompanied with UC in stability problem of the distribution power system in the case of three-phase fault occurring in the system. The harmonic and time-based results of the frequency and voltage before and after the presence of the proposed devices are analyzed and compared with each other.
