Analyzing the Effect of Loadability in the Presence of TCSC &SVC

چکیده
The loadability enhancement problem with loadability objective is solved in the presence of TCSC and SVC while satisfying system equality and in-equality constraints. It is necessary to solve the optimal power flow in the presence of series and shunt flexible AC transmission system controllers such as thyristor controlled series capacitor and static VAr compensators. The optimal location of these controllers is identified so as to maximize the system security. The optimal parameters of this controller and system are identified using the developed gravitational search algorithm. The effectiveness of the proposed methodology with TCSC and SVC is tested on standard IEEE-30 bus test system with supporting numerical and as well as graphical results.
