OPTIMAL POWER FLOW AND TRANSIENT STABILITY ANALYSIS OF A POWER SYSTEM

Abstract

The power flow analysis is used to determine the power flow of the system and also to determine the voltage
drop across each buses. By determining the voltage drop of each buses, FACTS devices can be placed across those buses
and the system efficiency can be increased and also the cost of the system can be reduced. There are a variety of
formulations with different constraints, different objective functions, and different solution methods that have been
labeled optimal power flow. FACTS devices has been proposed as the better alternative to overcome this, as in addition
to improving system performance, reliability, quality of supply and also provide environmental benefit. For determining
that optimal location power world simulator is used here. The continuation power flow is an accurate method for
estimating the maximum loading margin and determined the ‘weakest bus’. when the voltage collapse occurs. The
advantage of this simulated method is to develop a simple, fast, and convenient procedure which can be applied
effectively .Effectiveness of the proposed system is tested on IEEE-30 bus systems using power world simulator
