Modeling of Distributed Generators in 13 Nodes IEEE Test Feeder

This work aims to develop a model capable of evaluating the behavior of distributed energy resources in 13-nodes IEEE systems as a result of the change in the disconnector’s opening protocol that creates a power generation island. The first scenario simulated a failure in the 632-671 line isolating the subsystem into two 375 kVA distributed generation units (DG) in the nodes 675 and 652. Likewise, a second scenario considered the aperture of the disconnector located between nodes 671 and 692 representing a 375 kVA DG feeding a 900 kVA load. The last scenario produced a threephase failure modeling two 500 kVA DG units in the nodes 634 and 646 supplying an 800 kVA load.
