The multifunctionality of Energy Storage Systems (ESS) has being viewed as a powerful resource for a stable and reliable grid operation in an environment of high DER penetration at all voltage levels. The Portuguese DSO, EDP Distribuição, established a multi-sourced partnership with Siemens and the University of Évora, to implement, test and execute a pioneer Energy Storage project.

The most important of which are the oscillographic records, because they allow: fault location estimation; validation of relay settings; validation of coordination among protections. This important information traditionally resided in the protection units and could only be retrieved through vendor proprietary software. Retrieving this informatio...
