Keeping a smart grid balanced means responding in real time to fast changing conditions -- so sensors are a crucial part of smart grid technology. Siemens has partnered with the local municipal utility in Wachtendonk, Germany, where up to 80% of peak demand is supplied by photovoltaic power. Since solar power is notoriously variable, monitoring the grid in real time is essential.
Pilot projects such as this can be invaluable in preparing for large-scale smart grid deployments. In this pilot, Siemens installed smart meters with a special feature: power snapshot analysis. This captures and tracks crucial parameters that indicate grid stability.
Siemens also installed five new intelligent secondary substations, which can help compensate for the voltage dips that occur when clouds obstruct local solar power production. These substations also are equipped with communication-enabled switchgear, adjustable transformers, and components that support remote control and distribution automation.
Last week at DistribuTECH, Bruno Opitsch (Senior Key Expert for Distribution/Feeder Automation, Siemens Smart Grid) discussed the results of Siemens' studies of Wachtendonk and related pilot projects.
