Metodologia para análise de uma rede de distribuição utilizando OpenDSS e Python para obtenção de impactos devido à inserção de geração distribuída fotovoltaica

Abstract

This work seeks to identify the possible impacts caused by the insertion of distributed pho- tovoltaic generation in a real distribution system. This study is based on the Monte Carlo

methodology in which several scenarios are generated with variation in the location and penetration of distributed generations (GD), in addition to varying the daily consumption

profile of consumers. The analysis is performed using the simulation software Open Dis- tribution System Simulator (OpenDSS) together with the programming language Python,

using the Component Object Model (COM) interface as a way of connecting the program- ming code and the software. From this, it is possible to observe that for certain penetration

levels the system losses become smaller, however, at higher levels these losses can incre- ase. It is also observed that when there is a very high amount of generation, there may

be an increase in voltage, generating overvoltages in the network. In addition, the loading of conductors decreases as the DG is inserted into the network. Finally, it is clear that the

inclusion of distributed photovoltaic generation can bring positive or negative results, de- pending on its level of penetration.
