As a result of the deregulation of the energy markets,the separation of the vertically integrated structures ofthe past, and the sharp increase in decentralized powergeneration, the reliable management of power supplysystems is increasingly challenging. This developmentgoes hand in hand with the rapid growth in the demandfor communications. This is not just a question of higherbandwidths but also of communications requirementsfor new energy applications, including meter data management,distribution automation, and demand response,to name just a few examples. At the same time, energynetwork components like ring main units, distributedenergy resources, virtual power plants, microgrids, publiccharging, energy storage, and private households needto be integrated into the power utilities’ communicationsinfrastructure for smart grids.
Evolution of communications technology …
In a parallel process, communications technology hascontinued to develop rapidly over the past few years,and Ethernet has become the established standard inthe power supply sector.International communications standards like IEC 61850 will further simplify the exchange of data between differentcommunications partners.
Migration to a smart-grid communications network …
This means that the power utilities’ mostly heterogeneouscommunications networks, with their gaps in coverageand bandwidth, need to be migrated to a smart-grid communicationsinfrastructure. That will provide IP/Ethernetconnectivity between most components. The gradualmigration of most conventional communications interfacesand products toward TCP/IP-based networks and the extensionof network access down to the consumer level are thereforean important task for decision makers at powersupply companies. To meet these challenges, a teamorientedand interdepartmental planning of migrationconcepts is required.
