Transitórios Eletromecânicos em Sistemas Elétricos com Forte Geração Fotovoltaica e STATCOMs para Suporte de Resposta Inercial - [Not available in English]

The increase in photovoltaic generation affects the performance of the electrical system in the face of disturbances due to the fact that this type of source does not contribute to the regulation energy of the system. In the literature, several studies on strategies to mitigate this problem can be found. However, most of these studies use very detailed models that consider high frequencies, outside the range of interest of electromechanical phenomena, which restricts the simulations to small systems. In this work, an inertial strategy based on STATCOMs is applied in a study of transient stability. Electromechanical models of these electronic devices are used, obtained from a synthesis of the literature on the subject. The results obtained in the simulations show how these devices act favorably in the balance of active power and in the regulation of frequency.
