Paper Details

The blackout of power system in India in 2012 has indicated that the operation and control of powersystems may need to be improved. Even if a lot of data was available, the operators at different control centers did nottake the proper actions in time to prevent the blackout. This depends partly on the reorganization of the control centersafter the deregulation and partly on the lack of reliable decision support systems when the system is close to instability.Today a large problem for system operators is to identify critical states since there are thousands of parameters whichdescribe and affect the state. Motivated by these facts, in this dissertation, we have consider a hypothetical three bussystem and by using Newton –Raphson iterative method we have compare variation in voltage magnitude(V) and busvoltage angle(δ). Due to which, there is significant changes in both active and reactive power (more specifically reactivepower).We have verified our results by using MATLAB Program for power flow studies using Newton –Raphson Method.This Paper concludes that FACTS is a technology which provides a methodology for the utilities to effectively utilizetheir assets, enhance transmission capability by loading lines to their full transmission capability, and therefore,minimize the gap between the stability and the thermal limits, and improve grid reliability.
