Estudo da capacidade de hospedagem de geração fotovoltaica na rede teste IEEE 123 barras

Abstract

The integration of photovoltaic systems (PVS) at high penetration levels poses significant challenges to the electricity grid that warrant careful consideration. Issues such as reverse power flow and voltage level increases cannot be overlooked. Additionally, in residential settings, where photovoltaic systems are typically single-phase, there is a propensity for voltage imbalances to arise. In order to address these concerns, this study comprehensively analyzes the impact of PVS integration into distribution systems using deterministic load flow and hosting capacity methodologies. The evaluation is conducted on the IEEE 123-bus test feeder considering various scenarios, with photovoltaic systems randomly placed based on consumer load distribution and using the Open Distribution System Simulator (OpenDSS) software for simulations. The findings indicate that the presence of photovoltaic systems can mitigate conductor overloads and alleviate overvoltage conditions along the feeder, depending on the operational parameters.
