Proposal of an Inverter-based DER Model on OpenDSS Under IEEE 1547–2018 Regulation

Renewable sources have gained great importance in the search for energy production, because of their possibility of expansion and being increasingly accessible. Therefore, this paper aims to present two models of distributed energy resources (DERs), working during normal and abnormal voltage conditions, following the guidelines presented by IEEE Std 1547–2018 running on OpenDSS simulation software. Computer simulations were conducted using IEEE 13-Node Radial Test Feeder for both applications. The results show that all five operating modes proposed by the standard within the continuous operation region work as provided for by the standard. Moreover, for an Under-voltage (UV) scenario where a three line-to-ground fault (3LG) was applied, the model was able to contribute with current control supporting the network. Finally, for an UV scenario, it was seen that the DER impacts the network differently depending on its position, whether increasing substation current or increasing the current through the fault node.
