Abstract
This article presents an innovative methodology for analyzing power flow and assessing the impacts of wind and solar generation on the transmission network of the National Interconnected System (SIN). The proposed approach combines security region simulations with historical data on capacity factors, taking into account the correlation between this data and the intermittent characteristics of these sources. A case study was conducted in the states of Rio Grande do Norte and Ceará to demonstrate the robustness of the methodology in the face of variations in the generation of wind and solar plants. In addition to providing insights into the exposure time to overloads in the electrical network equipment and quantifying possible energy constraints of the plants, the proposed methodology offers valuable support for studies of Special Protection Systems (SPS), among other benefits.
