The CLS Operator for the Digitized Energy Turnaround

The German Digitization of the Energy Turnaround Act provides the framework of an economically viable rollout of intelligent metering systems (iMSys) as per 01 January 2017.

Thus, the fields of grid operation (IDS GmbH) and metering systems (GÖRLITZ AG) are becoming ever more closely linked.

VIVAVIS has already initiated a wide range of business processes required for this rollout, in order to provide the best possible support for the implementation of the Digitization Act.

Benefits of VIVAVIS at a Glance

  • Solutions for metering systems (GÖRLITZ AG) and grid operation (IDS GmbH) from one source
  • Solutions for IT security
  • Extensive know-how in all related areas thanks to strategies involving all members of VIVAVIS, as well as involvement and cooperation in relevant panels and research projects
  • Reduced synchronization efforts and workload thanks to integrated, comprehensive solutions

Portfolio of IDS GmbH

IDS GmbH provides extensive experience and products in the field of SCADA/network control. With a view to the digitization of the energy turnaround, we rely primarily on our HIGH-LEIT SCADA system, whereas our ACOS EEM tool is particularly for the management of renewable energy systems. We have also developed strategies for CLS management. Cryptographic tasks are solved by using technologies that are identical to those of Görlitz AG, thereby significantly reducing the complexity of encryption processes.

With a view to network operation and control, IDS GmbH offers the following solutions for the digitization of the energy turnaround:

  • Updatable  HIGH-LEITSCADA system
  • Expandable ACOS 730 control box for installations > 100kW
  • Solutions for power grid management (feed-in management, load control etc.) based on ACOS EEM
  • CLS Operator

GÖRLITZ AG - Portfolio

GÖRLITZ AG  are experts in the field of metering systems, offering tailor-made solutions for the installation and operation of smart metering systems based on their products IDSpecto.DAYOS and IDSpecto.GWA

These software packages are suitable for different fields of applications, reflecting the separation (as stipulated by the German BIS Agency) between the application itself (administration of SMGWs) and cryptography/IT security. The two systems are similar in that they both share the uniform use of the necessary crypto-technology, thereby considerably facilitating the introduction of these systems.

With a view to network operation and control, GÖRLITZ AG offers the following solutions for the digitization of the energy turnaround:

  • Solutions for SMGW administration (IDSpecto.GWA)
  • MDM system (IDSpecto.DAYOS)
  • Control box acc. to the specifications of the VDE Network Technology Forum (FNN)
  • SMGW
  • CLS Operator

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. 

Control Box

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
  • switching
  • 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.

The German Act on the Digitization of the Energy Transition

The German Act on the Digitization of the Energy Transition pursues the strategy of an economically useful roll-out of intelligent metering system (iMSys) starting on January 01, 2017, thanks to which the fields of grid operation and control (IDS GmbH) and metering point operation (GÖRLITZ AG) become even more closely integrated.

In order to control new systems in accordance with the requirements, power suppliers need new technologies and a modified ICT infrastructure. For the time being, existing installations and controls are protected by the status quo.

  • For the owners of power generation plants, this means that
    power meters may only be remote-read for billing purposes via the Smart Meter Gateway (SMGW) if plants are larger than 7 kW they may no longer be telecontrolled but must be controlled by means of the intelligent measuring systems via control box.
  • For grid operators this means that
    with a view to power generation, they may only intervene into processes via SMGW (production management) control boxes are connected via the CLS interface (CLS = Controllable Local System) of the SMGW conclusions concerning the grid status (balance of power supply and demand) are provided via SMGW.
  • For the owners of metring points, this means that
    in the future, they have to read out information (e.g. for billing purposes) via SMGW
