After a highly successful research- and demonstration project, the GridBox Technology is now being commercialized within the scope of a spin-off project. The company smart grid solutions AG (website), led by Martin von Euw, will take the technology to market maturity. Supercomputing Systems AG is the technology partner of the new company.

Concerning this matter, read this press release:

 

Zurich, 27th of September 2016

Establishement of smart grid solutions AG:
Spin-off of the largest Smart Grid demonstration project in Switzerland

The project partners of GridBox, the largest smart grid demonstration project of Switzerland, have now established smart grid solutions AG. The company aims at the industrialization of an innovative grid management solution and its further development. Using the new platform smartbox, the pioneering GridBox technology as well as the acquired knowledge of the successful one-year-trial are being unified in one solution.

Thus, smart grid solutions AG offers the distribution grid operators an intelligent and scalable solution, which is able to manage current and future technical challenges. Anton Gunzinger, entrepreneur and member of the board of directors of smart grid solutions AG, explains the use of the real time management systems as follows: “Due to the increase of decentralized producers, battery storage solutions and E-mobility, grid operators will face new challenges, or are already facing them. The smartbox is a tool to master these tasks and does not only serve one single purpose, but as a platform it supports a variety of tasks, services and business models of the grid operators.”

The smartbox technology is the comprehensive platform for a modern distribution grid management. As a coordinated and spread solution it guarantees for a safe yet economic network operation. Thereby the smartbox covers a multitude of requirements. Applications like fault detection- and localization, extended network monitoring, support of the asset management, prosumer-applications as well as market functions, featuring real time characteristics are being unified on just one platform.

 

By applying this generic approach, smart grid solutions AG offers a flexible and scalable measuring-, communications-, and control platform, which allows for a rapid implementation of new business models and therefore already has the answers for tomorrow’s challenges.

Press Release (PDF) from 27.9.2016

In collaboration with BKW, ewz and Bacher Energie AG, as well as co-financed by the Federal Office of Energy (FOE), SCS AG has successfully fulfilled the GridBox measurement and demonstration campaigns by March 2016. The GridBox project demonstrated a real-world instance of a full featured smart grid concept. Two distribution grid regions were equipped with almost 150 Gridbox devices: an urban quarter of the city of Zurich as well as an alpine region around Bern (Kiental). The development comprised of the measurement and control box, the communication infrastructure, the central intelligence software as well as data archive and analysis tools. A large number of research campaigns have been conducted on the GridBox platform for more than a year of full operation.

The primary results of the project are:

  • Demonstration of the feasibility of a real-time management platform for the distribution grid (low- and medium-voltage levels)
  • Development and demonstration of an advances real-time state estimation for distribution grids
  • Topology detection based on pure grid measurement data (calculation of the grid graph and identification of electrical characteristics)
  • Demonstration of a real-time optimization of the distribution grid state by influencing loads and infeed:
    • In households: control of water heaters, heat pumps and solar inverters (P and Q)
    • Within the grid: Control of a large grid battery (500kWh)
  • Recording of detailed grid measurement data in a specific archive: 150 measurement points, 1 Hz, including PMU-information
  • Evaluation of PMU functionality in the distribution grid

The box measures voltages and currents (12kHz resolution) with GPS-synchronized phasor information. The measurement data is preprocessed and communicated to a central data processing unit once per second. The box allows the control of flexibilities such as water heaters, heat pumps, solar infeed, batteries, e-mobility etc.

The core team at SCS encompassed ca. 7 engineers. The full project team including partners amounted to about 35 people including developers, data analysts, installation personnel, IT personnel and project management. We highly esteem their active contributions and commitment in order to bring this project to a successful finish.

GridBox will live on – commercialization is planned.

In cooperation with BKW (Berne), ewz (Zurich) and BEAG (Baden), Supercomputing Systems AG develops a holistic smart grid platform that will help to make distribution grids future-proof:

The electrical energy system is undergoing fundamental changes. Efforts to decentralize the system that is historically based on central energy generation and top-down distribution. Large power stations might be replaced by many local energy generation units like PV, water power, wind power etc. In addition, regulatory requirements are changing and energy markets see new rules of the game. All these transformations have an impact on the electrical distribution grid which will have to be more dynamic, less cost-intensive and more intelligent in the future.

GridBox is a generic platform for the intelligent grid of the future: Distributed measurement and control devices (intelligent PMUs, phasor measurement units)  collect data about the grid every second and communicate the grid state to a local master agent. The master agent implements algorithms for grid stability, grid monitoring, asset management aspects, market aspects etc. and takes control of the grid through a set of available actors such as PV inverters, electrical water boilers, batteries, e-car loading stations etc. The platform therefore is a real-time control system for the distribution grid.

The GridBox platform enables additional applications such as power quality measurements, grid monitoring, virtual power plants, support at grid dimensioning, coordination of PV and batteries in homes, smart markets with real-time price signals etc.

SCS has developed an open model for the simulation of different energy supply scenarios in Switzerland. The model makes it possible to calculate energy and activity balances depending on the chosen generation system, the degree of development of volatile energy sources (taking into account site and weather data), the degree of development and use of central and local storage facilities, the storage strategy etc. The model thus allows the direct comparison of various scenarios.

The model has already been presented at various public events. As part of a short presentation various scenarios are presented and subjected to technical plausibility checks. Pertinent findings for Switzerland’s future energy can be derived from this, which in turn can serve to stimulate debate.

The model is being continuously expanded and will be available to the public in the foreseeable future. It aims to set the foundation for a transparent energy debate that is as “de-emotionalised” as possible.
