Supervisor Control of Power System for Stability Problems and Improvements Using Computer Control Technology

Abstract

Currently, there is a growing interest in the topic of power quality across the entire electric power system. The power system is a complex network of modules with a broad distribution area, designed to meet the demand for electric power. The power system is susceptible to a range of disturbances arising from either dynamic consumer load behavior or faults. The power system necessitates a precise and advanced stability and protection mechanism. Ensuring the safe and reliable operation of the power system is a significant challenge, with voltage stability and fault protection being key areas of concern. The present research study proposes a technique to augment the stability of a grid-connected system that comprises of several generating sources through the utilization of FACTS devices, specifically static synchronous compensator (STATCOM). The technology has been designed to enable the monitoring of supervisory control of devices, while the distribution system offers decision-making tools to enhance system performance. A fault was generated between the time interval of 1-1.04 sec duration, and the simulation waveform was subsequently observed. The present study entails a simulation-based comparison between a power system without a STATCOM devise and one equipped with the STATCOM. The analysis results of the transient voltage stability of HV AC transmission lines utilizing STATCOM.
