Using the Monte Carlo Method to generate random and realistic scenarios, a probabilistic analysis of the network is performed to reflect the unpredictability of a real system and to develop a predictive analysis for harmonic distortions. For the simulation of the IEEE 123-bus test feeder, the integration between the OpenDSS software and the Python language is used to apply various load, irradiance, and photovoltaic penetration levels to the system. The investigation assesses the impact of harmonic frequencies on the network, quantifying the penetration threshold at which the system transitions from a state of compliance to a condition of systematic violation of regulatory limits, and demonstrating that the risk of non-compliance becomes a statistical certainty in scenarios with a high density of distributed generation.Acesso Abertophotovoltaic systemsharmonic distortionMonte Carlo methodpower qualityopenDSSdistribution networksistema fotovoltáicodistorção harmônicamétodo Monte Carloqualidade da energiarede de distribuiçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICATrabalho de Curso - Graduação - Monografia
