A new approach for area interchange control modeling

This paper describes a new methodology to evaluate the area interchange control (AIC) in a power flow problem using the Newton-Raphson method. In this methodology, the equations of the AIC are incorporated into the system of equations of the power flow problem. Thus an augmented system of equations, which is linearized and solved, at each iteration, is obtained. The proposed method has been tested and compared with existing methods in the literature using both small and large scale systems. The results presented validate the proposed technique.
