Análise e simulação de modelos matemáticos para usinas solares fotovoltaicas

Abstract

The study addresses the modeling and simulation of grid-connected photovoltaic solar power plants, focusing on control techniques to maximize system efficiency and stability. The increasing penetration of distributed generation, particularly photovoltaic, imposes significant operational challenges, such as intermittency and voltage fluctuations. This work compares two simulation models: an average model, which simplifies large-scale analysis by disregarding high-frequency harmonics, and a detailed model, which captures transient phenomena and the switching dynamics of converters. The results indicate that the detailed model is more suitable for power quality studies and critical events, such as short circuits. Additionally, harmonic distortions and the impact of DC components on voltage and current signals are analyzed, highlighting the need for robust control and protection techniques to ensure the system's safe operation.
