Desenvolvimento de interface para análise do impacto de sistemas de geração distribuída e de armazenamento de energia em redes de distribuição

This paper presents the development and testing of a graphical user interface designed to analyze the impact of distributed generation and energy storage systems in electrical energy distribution networks. The OpenDSS software is used to model the network and calculate the power flow, while the graphical interface was developed in Python. The new interface developed allows (i) the visualization of the geographical layout of the medium and low voltage grids, (ii) the insertion of PV distributed generation and/or energy storage systems, (iii) the dispatching of the energy storage systems in six different ways and (iv) practical evaluation of the results obtained from the load flow study such as: load factor, technical losses, steady-state voltage variation, amount of injected energy, the state of charge of the storage system batteries, etc. More comprehensively, the interface allows the simulation of different scenarios and the choice of the best network configuration for different purposes in order to optimize the use of distributed energy resources.
