EEBUS

from Wikipedia, the free encyclopedia

EEBUS (pronounced: "E-Ebus") stands for a communication interface based on standards and norms that can be used freely by any device and any technical platform, regardless of manufacturer and technology. EEBUS aims to enable energy providers and households to exchange applications and services to increase energy efficiency. Specifically, EEBUS stands for a common and manufacturer-independent language for energy management in the Internet of Things . Manufacturers can freely use the EEBUS specifications.

The aim is that energy providers, households and energy-relevant devices can exchange data with one another in order to increase overall energy efficiency. Only then can the potential of intelligent households and power grids really be realized. Cross-sector communication offers companies the opportunity to develop new products, services and business models.

The EEBUS initiative is driving the development of EEBUS . The members of the association define together, based on identified market needs, specific cross-sector application scenarios for energy-relevant devices, which are then standardized as use cases within the framework of EEBUS. In order to enable the implementation and development of interoperable products and services, EEBUS also standardizes the necessary technical specifications.

initial situation

Future systems of electrical energy supply will be shaped to a greater extent by volatile sources such as wind or solar energy and will be more decentralized than they are today. This development will require a more intensive exchange of information in the form of intelligent power grids between all participants. Private households in particular will play a more active role than before. Options currently discussed include:

  • You appear not only as a consumer, but also as a producer, e.g. B. with their own photovoltaic systems or combined heat and power plants . These generation plants may be organized as virtual power plants . This includes the option of generating the electricity required locally from the outset and thus helping to relieve the load on the grid.
  • They provide the battery capacity of their electric vehicles connected to the grid as a buffer to compensate for short-term fluctuations in production and consumption, or they charge the vehicle with self-generated electricity.
  • To set up their consumption at the current power generation by the operation of powerful consumers in times of great power supply shifts will. All household appliances whose operating times can be varied without any loss of functionality are suitable for this load shift, e.g. B. heat pumps, refrigerators, dishwashers, etc. According to the BDEW annual statistics from 2009, around 80% of domestic electricity consumption falls into this category. According to a study, such relocations would also be accepted by the user. By making electricity purchases cheaper with variable tariffs when there is a large supply and / or low network utilization, the energy supplier creates the incentive for load shifting.

All these scenarios assume that all participants can exchange information on energy management with one another:

  • Locally, all producers and consumers belonging to the household can communicate with one another about production and consumption values, load profiles and forecasts, etc. and coordinate their operating states with one another.
  • A bidirectional exchange takes place between the energy supplier and the household. a. of tariff information and measured values, which is largely automated and takes place without personal intervention by the user.

The EEBUS Initiative is a non-profit association that represents the interests of all members equally. The board of directors is elected from representatives of the member companies. In addition, the member companies work in the EEBUS working groups and task forces on the further development and implementation of the standard. The democratic structure ensures that EEBUS is independent of the interests of an organization or individual interest groups.

The EEBUS Initiative currently has 67 members (as of October 2017) who represent a variety of industries and sectors, and for whom the development of a manufacturer- and technology-independent communication standard is strategically important. The companies are mainly from the fields of heating and cooling technology, automotive, energy supply and service providers in the field of smart home and smart energy .

Structure of EEBUS

Classification of SPINE and SHIP in the SGAM framework

The core component of the technical specification is known as SPINE ( English Smart Premises Interoperable Neutral Message Exchange ). It describes the application scenarios defined by the EEBUS members in the form of data records that are compatible with a large number of protocols and transmission channels (WLAN, Thread, KNX, etc.) and thus interoperability with various smart home and smart grid technologies enable.

Any technology that supports the bidirectional exchange of any data can be used with SPINE. Direct use is possible with the encrypted and for SPINE native TCP / IP protocol SHIP (Smart Home IP) or with other IP-based transport protocols (e.g. thread). Data mapping is required for other communication technologies (e.g. KNX , Modbus , ZigBee ) .

The current SPINE data model includes use cases for various types of energy management functions with a focus on the areas of smart energy, smart home & building, connected devices and e-mobility . The data model is continuously evolving, and additional domains and use cases are being added through the work of the EEBUS initiative .

SPINE and SHIP can be classified in the Smart Grid Architecture Model (SGAM) of the Smart Grid Coordination Group and in the Home & Building Architecture Model (HBAM) derived from it.

Joint further development of EEBUS

EEBUS connects market and technology through a clearly defined process.

The working groups are the driving force behind the technical development of EEBUS. There, the EEBUS members work together to develop and define which cross-product and cross-manufacturer application scenarios are so sensible from a market perspective that they should be taken into account in EEBUS and standardized as use cases. They develop common data models and data exchange for their interfaces to external systems; this only standardizes what is wanted by the member companies.

By dividing into private and shared data, every company can retain complete sovereignty over its data and functions. This allows companies to become part of a larger ecosystem without endangering their own business model.

Before the release of new use case specifications, the use cases are tested in plug fests. There the practicability and robustness of the device communication is checked. Participants define a number of use cases in advance, which they then implement and test for mutual interoperability during the plugfest. The successfully tested use cases are consequently published as new EEBUS specifications.

The following working groups are currently active:

  • Photovoltaics & storage
  • Heating, ventilation & air conditioning (HVAC)
  • White goods
  • E-mobility & connected car
  • Commercial
  • In addition, a working group for the interface to smart metering / regulated energy market is in preparation.

standardization

In May 2010, the German Commission for Electrical, Electronic and Information Technologies (DKE) published a standardization roadmap on the subject of E-Energy / Smart Grid. EEBUS implements the recommendation drawn up there. At the European level, EEBUS was part of the Smart Grid Coordination Group for the first time and focused on the interface between the Smart Grid and the Smart Home. In the last few years the standardization process has been driven mainly on a European basis.

The EEBUS data model is already part of international standards:

  • CENELEC EN 50631 (Interoperable Connected Household Appliances)
  • ETSI TS 103 410-1 SAREF4ENER (EU Framework SAREF; Smart Appliances REFerence)

In addition, EEBUS is also active, for example, in the following standardization bodies at CENELEC, DKE, ETSI and IEC:

  • CLC TC205
  • CLC TC59x
  • 1711.x / 901.x /802.x
  • DKE / AK 353.0.101
  • DKE K716
  • ETSI oneM2M
  • IEC TC57
  • IEC TC59
  • IEC62746-2
  • prEN50491-12

Partnerships with other alliances

  • Energy @ Home
  • OCF (Open Connectivity Foundation)
  • Thread Group
  • ESMIG

criticism

Until mid-2016, EEBUS was to be regarded as a proprietary technology, as no technical details about the standard or the data models were publicly available. On May 18, 2016, a press release from the EEBUS Initiative announced the immediate disclosure of Specification 1.0 of the EEBUS standard, also for non-members. The specifications are now available to anyone on the EEBUS Initiative website by providing their contact details.

The specification relevant for white goods is available in the CENELEC EN 50631 standard. In addition, the ontology to which the SPINE relates has been incorporated into the SAREF4ENER specification ETSI TS 103 410-1.

membership

In contrast to non-members, the EEBUS member companies actively design all new areas of application for new use cases of the EEBUS specifications. This means that member companies can test EEBUS communication in their products and in interaction with the systems of other member companies even before the official standardization of new applications, for example in a plug festival that takes place regularly for individual application areas in EEBUS. Membership in the EEBUS Initiative costs 10,000 euros annually, smaller companies and partnerships can apply for membership at half the price (as of January 2017).
