Battery Storage Engineering for Stand-Alone and Co-Located Sites
Varian Energy engineers battery energy storage systems both as stand-alone installations and in combination with photovoltaics and wind, covering layout, electrical design, grid connection, protection, metering and communication concepts as well as clarification of interfaces between grid operator, certifier and suppliers.
© TEOS EnergyEngineering, interfaces and documentation as one system
The technical focus is a clean definition of system boundaries: where the storage system ends, where the generating plant begins, how control is applied at the point of connection and which information has to be exchanged between the storage system, the power plant controller, the network operator and energy trader.
- Engineering driven by expertise and experience
- Interfaces clearly defined
- Documented for review
Technical scope in detail
The service modules are clearly structured and can be combined to match the project phase, plant configuration and technical requirements.
