Present distribution networks have not been designed to accept extensive Distributed Generation (DG). The present framework may change in the near future impelled by a worldwide increase in DG penetration in distribution grids. The mutual dependency of energy distribution and communications on the same grid requires new means for effectively monitoring and controlling both systems in parallel. Relaying and control IEDs can also serve as measurement units for power quality. Synchronized Measurement Technology (SMT) has the potential of becoming the backbone of this paradigm. By using wide-area information systems, the data can be made available to all involved partners. This paper provides different outlooks about the possibilities of Embedded Systems to integrate the protection, control and monitoring functions in Distribution Automation Systems. To justify the choice of synchronization technology, we have scheduled a complete sequence of synchronism tests and measurement tests based on standard specifications.
