Voltage stability limit improvement Of a power system by optimal Location of facts devices through Nature inspired algorithms

Abstract

A power system is said to be well designed if it gives a good newlinequality of reliable supply Voltage level maintained within the acceptable newlinelimits is referred as good quality here In current power markets control of newlineactive and reactive power flow in a transmission line becomes a necessity newlineaspect Entry of more power generation companies in a deregulated power newlinemarket has increased the need for enhanced secured operation of power newlinesystems Increased reactive power flow though lines is more likely to cause newlinevoltage instability This is because of uncontrollable decline in voltage levels newlineat load buses Those systems are facing the threat of voltage instability newlineleading to voltage collapse Also the stable operation of the power system newlinenetworks revolves around improving voltage profile minimizing power newlinetransmission loss An aspect of interest here is quantifying the loss accurately newlineand adopting measures to minimize the loss thereby resulting in improved newlinepower transfer capability newlineVoltage stability and real power loss analysis are essential for newlinesecure operation of a power system Many works have been developed to newlineimprove voltage stability and minimize the real power loss newline newline
