Summary
There has been an unprecedented growth in the rate at which renewable energy integration is happening in the modern-day Power System. While RE integration stands as one of the most prominent solutions to decrease carbon footprint, it is apparent that the Grid stability and resilience is dynamically challenged. Without suitable compensation, the RE integration poses a serious threat to the reliability of the electrical Grid. Wide Spread grid outages may result because of such uncompensated RE networks, which can often have cascading effects and may lead to wide spread blackouts, resulting in heavy economic losses.
Read more Read lessStatic Synchronous Compensator’s (STATCOM’s) have long been envisaged as a solution to address the Grid Stability issues in view of increased RE integration. A STATCOM station provides excellent dynamic compensation to electrical grid, enhancing the stability limits of the
Power System, while also providing static voltage compensation, thereby improving the power quality.
This paper discusses and vindicates the practical response of STATCOM station installed in the southern region of India, to the various types of faults in the Grid. The static and dynamic capabilities of STATCOM station are illustrated through actual Transient Fault Recorder traces captured during testing of the system and the real-time response to grid faults is demonstrated subsequently.
The illustrations to be presented in the paper show a conclusive evidence of the effect of
STATCOM stations in safeguarding the grid stability in view of the present challenges to grid reliability posed by exponential RE integration. The response of STATCOM stations during faults in power systems is seen to be similar to the excitation response of synchronous generators. Also, the real time voltage compensation (static) can also be achieved through
STATCOM stations. Hence, it can be concluded that installation of STATCOM stations is the need of the hour for sustaining the transition from the energy generation and grid operation through conventional/ fossil fuel based generation to energy generation and grid operation from renewable sources.
