Balancing supply and load is a challenge in a market with a growing energy demand and multiple decentralized energy resources. Even the most advanced management systems require numerous field devices to monitor and control the process level. Those devices have usually to be compact, cost-efficient and provide a secure communication interface even in remote locations. SICAM SGU 7XV5676 has such a secure and cellular communication build to connect with an energy management system. It can be used for smart grid purposes as various as demand response, DER controller for virtual power plants, renewable integration in microgrids, or small RTU. (EEG-Box only for German version)
SICAM SGU – simply powerful
Based on a powerful and future-proof hardware and soft-ware platform, SICAM SGU is designed for substations and rough industrial environment requirements. SICAM SGU is ready for today’s and tomorrow’s needs. The parameter setting of the SICAM SGU is simply carried out with a standard Web browser at the PC which is connected via the Ethernet interface. No special engineering tool is required.
Open ADR - Fit for demand response
The SICAM SGU can be used as a field device in any demand response management system (DRMS) via the use of the interoperable and secure communication protocol Open ADR, a growing Smart Grid standard where Siemens plays a key role with its expertise and integrated solutions.
Even cellular wireless integrated!
The SICAM SGU can be used with an integrated GPRS modem to connect remote distributed energy resources. SICAM SGU provides a cost-efficient alternative to expensive wired installations and separate configuration of an external cellular modem. The SICAM SGU is supporting the most widespread 2Gcommunication technology worldwide, GSM/GPRS, perfectly adapted to the required bandwidth of IEC 60870-5-104.
And an optimal end-to-end security on top!
A VPN connection, based on IPsec, provides your application a secure way without intermediates. Even without IPsec, the integrated TLS provides end-to-end security for the Open ADR communication.
