SHORT-TERM TREND OF PROCESS ORIENTED POWER SYSTEM SECURITY BASED ON LOAD PROFILE

Abstract

Power system analysis is necessary for planning, operation, economic scheduling and exchange of power
between generation to load center. The primary information of power flow analysis is to find the magnitude and phase
angle of the voltage at each bus and flowing of the real and reactive power in all transmission lines. This paper presents
an introduction to the concepts and methods for “ short-term trend security analysis” of power system”. This work
presents a solution methodology of process-oriented power system security using Taylor series expansion method for
power flow for without the contingency. Also, determine the power flow analysis using NR, FDLF and Taylor method are
applied to an IEEE14 node system and fast process oriented power system security using Taylor series expansion
method than Traditional method and evaluate their performance and verify their accuracy.
