Products from VIVAVIS and their Practical Application
CLS Management/CLS Operator
The implementation of control tasks for switchable loads, renewable energy sources, e-mobility and other energy-related tasks (e.g.peak/off-peak rate switchover) through the control box require more than just a simple logic for protocol adjustment. The CLS operator serves as an input interface, providing various services for the energy industry and fulfilling technical functions for communication with the control box. Examples are:
- Direct control commands (e.g. the smart grid traffic light is red)
- Configurations (e.g. peak-/off-peak switching times)
- Administrative tasks (e.g. certificate management of the control box)
- Priorization (e.g. grid has priority before the market) and other tasks
The intelligent design of this system is one of the foremost challenges in the integration of power grids and metering systems.
Smart Meter Gateway (SMGW)
The SMGW is the future communication unit in the customer's system. It enables logging of all billing-related data and their provision to authorized users in accordance with the regulations of the German Act on the Digitization of the Energy Transition. Moreover, this Act prescribes the communicative connection of the control box via SMGW. This means that each and every control tasks must be executed via the SMGW. The SMGW can provide metering data on how power supply and demands can be optimally balanced to benefit the grid.
In the future, the control box is more than just a replacement for a classic ripple control receiver. The increasing complexity of systems is reflected by the wide range of demands on control boxes with regard to
- Secure bidirectional communication
- Connection of field-bus systems
- Systemic services
- Additional basic functions and expansions
Apart from mere switching operations, control boxes must fulfil a variety of other functions to ensure their future-proof installation and operation.
This is important: Requirements on control boxes differ depending on the size of a system. For this reason, VIVAVIS offers control boxes both for large-size (>100kW) and small-size systems (6,000 to 10,000 kW).
Meters/Modern Metering Equipment (mME)
The metering device is and will be the means by which billing rates are measured in accordance with legal provisions, and are provided to the SMGW. In addition, however, the mME has to fulfil requirements concerning the safe connection to an SMGW and the provision of information to the final consumer via display. On these points, there have bee lively discussions in all the involved panels. As of January 01, 2017, the installation of mME's is mandatory.
Administration of the SMGW
In the future there will be a role for the remote administration of the SMGW. Access tot he gateways must be organized decentrally in order to guarantee security. This new technical function, referred to as Gateway Administrator, is subject to various demands on information security. For this purpose, the German BSI (German Federal Institute for Security in Information Technology) has defined several binding technical regulations concerning the security demands on the SMGW.
Meter Data Management (MDM)
The provision of processed data (decrypted, verified, aggregated data) for billing purposes is still the tasks of MDM systems. These systems are frequently used, yet they must be adjusted to the required security structure of the iMSys and the massive utilization of future data volumes. In this context, the changing technical approcach of ”old“ systems towards a process-optimized view in the bulk business and an integration of cryptography/IT security is of particular importance.
