Abstract

The continuous increase of Distributed Generation (DER) along the electrical grid can offer several benefits, such as microgrid operation. However, microgrid operation requires special attention and introduces new challenges to the distribution operators, in particular for the protection systems. In the SENSIBLE project, a H2020 project funded by the European Commission (EU), one of the objectives of the Portuguese demonstrator is to test the islanding operation of a LV secondary substation (SS) with grid and residential storage devices. In the context of this paper, the results of the protection tests performed under laboratory conditions at EDP Labelec are presented. For that purpose, a secondary substation low voltage (LV) grid was built, with the grid embedded storage devices connected to a LV busbar, which provide energy to a set of adjustable loads (three-phase heating fans). The studies were performed for all foreseeable configurations (parallel and island) to ensure clearing of faulted conditions, and with different load scenarios.
