This study assesses the applicability of EnergyPLAN, a simulation tool, for a high renewable energy source (RES) system, focusing on Brazil. By comparing EnergyPLAN outputs with data from the Brazilian National System Operator (ONS), the research evaluates its accuracy. Findings show high accuracy in annual and monthly simulations for photovoltaic and hydroelectric plants but higher errors in daily simulations for variable RES like wind and solar. The study highlights the need for better modelling of variable RES and offers insights into EnergyPLAN’s effectiveness for energy planning, contributing to more reliable energy systems.engEnergy planningEnergy systems computer modelingEnergyPLANconference paper10.1109/ICECCME62383.2024.10796235
