This paper presents an analytical approach to enhance the stability and power profile of a power system grid, particularly under fault conditions. It discusses the performance improvement achieved by connecting dynamic components like Static Var Compensators (SVC) to ensure reliability after transient events. The results indicate enhanced voltage and reactive power profiles, outlining future steps for further improvements in the power network.

4.  The initiation of fault in the Power System
introduces a high degree of transient behaviour leading to the
flow of a high value of current causing damage to the entire
system.
 System starts losing stability leading to high degree of oscillations in the system.

5. Main objective of the paper
 This paper presents an analytical approach to improve
stability and to enhance active & reactive power profile of grid
network mainly under fault condition.
 To obtain optimum performance of the grid network by
connecting certain dynamic components in the network
 To improve the network parameters and ensure the reliability
of power flow after a huge transient in the power system by
using FACTS device.

14. Conclusion
The profile of the receiving end voltage of the line determines
satisfaction level at the consumer end and is also responsible for
smooth operation of certain loads. Thus for a compensated network the
profile of both reactive power as well as voltage are enhanced. The
SVC basically provides reactive power compensation to the line. Since
voltage of the line is coupled with reactive power, it also gets
modified.

components in the network.
