Paper Title
Improvement in Power Flow Conditions using Sensitivity Analysis for Congestion Management
Abstract
As the power systems are becoming more complex it requires careful design of the new devices and systems for
the operation of controlling the power flow in transmission system. The researched systems should be flexible enough to
adapt to any momentary system conditions. Power-flow analysis or load flow analysis is a numerical analysis of the flow of
electric power in an interconnected system. The goal of this analysis is to obtain complete information of angle and
magnitude of voltage for each bus in a power system for specified load, generator real power and voltage conditions. Once
the required information is achieved, real and reactive power flow on each branch as well as generator reactive power output
can be analytically determined. Due to the nonlinear nature of this problem, numerical methods are employed to obtain a
solution within an acceptable tolerance. In this paper, Gauss-Seidel, Jacobian Series Code, Newton-Raphson, Tanikchalam
Sensitivity Analysis and Fast-Decoupled methods are compared with respect to their performances, convergence rates and
outputs for IEEE 14 bus system. Further, fact controllers i.e., static VAR compensator for improvement in the voltage profile
is also designed and implemented and a comparison is carried out for the voltage profiles with or without the absence of fact
controllers.
