Uma nova proposta para o controle de intercâmbio entre áreas

Abstract

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, where the new state variables are the active power generation increments at the AIC regulating buses. Thus an augmented system of equations, which is linearized and solved at each iteration, is obtained. In addition, a new approach for the representation of multiple AIC regulating buses at a given area is also presented. The proposed method has been tested and compared with existing methods in the literature using both small and large scale power systems. The results presented validate the proposed technique.
