Inclusão de transformadores reguladores no algoritmo de análise de fluxo de potência

Abstract

The electric power systems (EPS) are non-linear systems that are constantly changing during its operation. Since the EPS’s creation, its complexity has grown fast, implying the needing of more precise analysis. This research address modeling a small power system in stationary state, including regulatory devices on resolutions of power flow studies. Static modeling has been used, and the EPS’s descriptions are throughout non-linear equations. Hence, the Newton-Raphson method provides all voltages and angles of the bus network, with respect of a reference bus (swing, slack). In this report, the including of regulator devices in the power flow algorithm will be analyzed. The load-tap-changing (LTC) transformer and the phase-shifter transformer will be focused for software ANAREDE, and then, an algorithm will be developed in MATLAB©, including the LTC transformer in the equations for the power flow solutions. This work aims to modify the power flow algorithm, thus comparing the solutions for a more detailed analysis of EPS.
