Smart Neighborhoods speak EEBUS.
The aim of the workshop is to demonstrate how EEBUS enables an industrial approach for residential energy management by providing standardized device communication and energy management use cases. Hence, a lock-in into proprietary manufacturer specific communication can be avoided. This enables cost effective scalability, replication, and commissioning of energy management solutions at target markets.
EEBUS provides transparency and access to all energy relevant devices and thus transforms them into flexible resources for demand response. Single households become the core elements of Smart Neighborhoods and consequently of Smart Grids. The continuously evolving technology is open to further use cases and therefore facilitates the integration of other domains to the REnnovates technical platform – such as E-Mobility which is already managed through EEBUS or grid interaction.

Notes de l'éditeur
The main objective of the partly EU-funded REnnovates project is to explore the main business model opportunities to make investment in the renovation existing building stock financially viable.
The concept encompasses the deep renovation of houses towards net-zero-energy status and integration of houses into smart neighborhoods.
For a successful business case of deep renovation of existing.
building stock into zero-net energy and smart neighborhoods is an industrial approach necessary. This includes for example prefabrication of components, modular structures, and utilization of digital construction tools such as BIM.
Why standardized:
-Standards facilitate…
-Because standardized device communication and interfaces are essential for scalable and replicable energy management solutions
This includes Plug&Play- ready device communication and implementation of standardized use cases for energy management – independent from underlying device manufacturers or gateway software. To enable this approach was EEBUS software from KEO GmbH chosen as the technology for device communication in the project.
Is the concept of interoperability familar to you?
How would you define it?
Analogy between humans and systems:
People can understand each other, regardless how the communication happens: Letter, call, whatsapp or face2face talk. As long as the language is common can we communicate (of course has the medium for communication to match).
Benefits
This is what EEBUS does.
EEBUS is the global language for energy. It is the language for devices to communicate with one another about energy – transcending the boundaries of industries and continents. It is common language that every device and every platform can freely use – regardless of the manufacturer and technology. All key domains of residential and commercial energy consumption and generation - renewables, energy storage, e-mobility, heating & air conditioning household appliances and lighting – converge into one system.
EEBUS is represented and developed by the non-profit organization EEBus Initiative e.V. The initiative brings together almost 70 member companies and industry organizations, that together work on the standardization of cross-domain use cases for device communication over energy.
The starting point for the EEBUS standardization process is usually the market requirements of the companies involved, which they commonly define. These requirements are transferred into so called use cases. EEBUS Use cases describe the communication between two or more devices in order to fulfill a specific goal related to improved energy efficiency, visualization of energy relevant data or configuration of devices.
In a spirit of partnership the EEBus members develop use cases and decide which information needs to be shared to achieve the goals. Due to the fact that only information necessary for the use case is exchanged, can the companies both open themselves to a larger device ecosystem, but still maintain the feasibility of their horizontal business models.
The cross-industry network of the EEBUS members plays a key role in this process. Through the exchange of technology and market knowhow, is a common overarching understanding reached and future development for more efficient use of energy promoted.
The EEBUS approach in the standardization process is always geared towards application on real products on the market. This means that use cases are transformed to production-ready specifications and data models.
The specifications and product prototypes are tested on so called common Plugfests, where the correct function of new use cases is verified.
The EEBus Initiative works for global convergence through interaction with other international consortiums in the Internet of Things - such as Energy@home, the Open Connectivity Foundation (OCF) and the Thread Group. The EEBUS data models for energy relevant devices were last year included in the OCF resources, affirming thus the EEBUS leading position when it comes device communication over energy.
EEBUS creates interoperability through the Smart Grid architecture layers by describing Uses Cases and standardizing the underlying data models.
Smart Grid Architecture Model:
Describes actors, functions, use cases, communication and components within the reference architecture. It enables definition of responsibilities and requirements per layer to crete interoperability through all levels.
Enables any market participant to release market-ready interoperable products
Changes in the layers do not necessary require re-validation of the entire Use Case.
Smart Premise Interoperable Neutral Message Exchange.
SPINE is standardised:
Most recently has SPINE been standardized by the CENELEC, where it was included in a standard for smart household appliances. SPINE based on an ETSI standard for SAREF4ENER, which is a reference ontology for Machine-2-Machine communication and a benchmark for device interoperability on European level.
In addition, the alignment of SPINE with standards in other domains is continuously ongoing.
SPINE is independent of the transport level, and can thus be transmitted via many communication and transmission channels e.g. for the TCP/IP environment, EEBUS has published a specification called SHIP (Smart Home IP). Whereas in UDP environment cooperates EEBUS with Thread and OCF. To other technologies can the SPINE content be mapped.
The Rennovates concept is based on the following four elements:
Insulating the houses with a envelope
Installing an energy module
Smart energy control on each individual house powered by EEBUS communication
Smart solution to flexibilize the neighbourhood
As EEBUS is a standard for device interoperability is it not applicable for physical structures such as insulation, but for all other concept elements EEBUS is a central enabler. The following slides will handle the EEBUS implementation in the project, provided added value, and future development of the platform on EEBUS basis.
The software expertise provided by KEO GmbH in the Rennovates project enabled a successful EEBUS integration of all energy-related devices - such as measurements & metering, heat pump, photovoltaic inverter and building-level battery - in the local energy management gateway. Manufacturer specific communication was mapped with KEO software into the technology neutral data model SPINE and transferred over the KEO EEBUS Framework to the Enervalis technology. Flexibility enabling use cases – for example smart start and stop of heating, battery charging, inverter control and local optimization – were thus made possible.
A successful cross-domain energy integration to enable efficient and truly smart energy management was essential to realizing the energy-savings potential and reaching the Rennovates target for housing Zero Net Energy status. Moreover, this could be done in a financially viable, scalable and replicable way. For KEO the project experience resulted in a mass-market suitable roll-out of Plug&Play qualified EEBUS communication solutions.
Firstly, plug&play ready device interoperability with the EEBUS solution from KEO solves the major challenge the integration of devices into compact modules and systems creates: development of device and manufacturer specific solutions, that are expensive to maintain, scale and replicate. Once the energy management is also set up with EEBUS data models and Use Cases, system components can be exchanged without expensive and complicated re-integration efforts. Utilizing standardized EEBUS use cases enables extending the modular approach to the energy management both on house and neighborhood level. Thus, implementing EEBUS on both device and energy management system level promotes platform scalability as well as replicability.
Secondly, integration of all devices into one system enables a holistic approach for managing the energy flows of households and as well reduces technical complexity. This is a driver for both energy and cost efficiency.
Thirdly, standardized device communication enables networking of all energy relevant devices and thus creates the infrastructure for smart energy control on individual house level. A house with intelligent and networked devices is the core element of a flexible neighborhood. Consequently, a must for improved flexibility and transparency to residential loads and resources, which furthermore enables creation of new services and business models (i.e. Smart Neighborhoods as product, or bundling of demand response with other consumer services).
Other benefits:
In addition, an energy management solution based on EEBUS data models is open for a future integration of other energy relevant devices and domains, such as e-mobility.
For optimal development of the Rennovates platform, should native EEBUS devices be used. However, this requires a wider market penetration of EEBUS technologies. This development should be supported with appropriate incentives that encourage technology providers to improve interoperability with other ecosystems. For further interoberability, EEBUS is compliant to the common European reference language for energy (SAREF4ENER).
The development of standardized EEBUS high-level use cases for multi-family houses and commercial buildings should be driven in the working groups of the EEBUS Initiative. Up to now Rennovates platform services – such as energy savings, solar self-consumption and solar forecast – have been implemented on proprietary technology that creates certain degree of barriers and lock-in conflicts to other services. Realizing these services with standardized EEBUS use cases will significantly promote the scalability and replicability of the platform in the future.
Furthermore, additional services could be offered by developing new use cases for e.g. the integration of e-mobility into smart neighborhoods or information exchange with the DSO and other grid stakeholders.
Basing the energy management on freely available – non-proprietary - EEBUS data models and use cases would also make setting up platforms for smart and flexible neighborhoods possible for a larger group of stakeholders. This would improve energy efficiency and reduce the CO2 footprint of the whole building sector in the European Union.
Back to EEBUS
As the practical use cases from EEBUS show, has EEBUS already networked the energy relevant devices in the household. However, to unleash the full potential of an energetically networked house is grid interaction necessary. E.g. from a grid operators point of view does purely local use cases not provide much added value neither does it enable a smart grid. Thus are also use cases for interaction with the grid necessary.
This especially because e-mobility will increase electricity consumption and its volatility significantly. To manage overload and underload scenarios through the existing grid infrastructure a bi-directional communication from grid level to cell/device level (e.g. e-vehicles) is required.
Standardizing meaningful use case for the connected home. All devices within a house are connected with the local energy management (EMS) which optimizes the energy self consumption, using EEBUS data models and use cases.
Example of such an use case: Overload Protection
To prevent an ongoing EV charging process from tripping a fuse of the supply side infrastructure. -Enables the system to limit the maximum charging current of the EV on each phase depending on the electrical connection.
-> Added value: The power consumption of the EV may be reduced and thus the house protected from blackout
However, protecting the house from blackout is not enough. Consider that if the main fuse can handle a load of 20kW and there are 10 houses in the neighborhood, does it not mean that the local transformer can handle a load of 10x 20kW.
Information exchange between Smart Home and Smart Grid a must.
Grid connectivity
-> Added value: Local cell / grid can be protected.
For linking the Smart Grid with the Smart Home has EEBUS developed the Power Limitation use case, which takes use of the house internal use cases enabling power limitation of energetic processes. In the EEBUS approach will the EMS will aggregate energy demands/offers and manage e.g. set points for power limitation provided from the grid side stakeholders.
In Germany will this connectivity be realized over the smart meter gateway, for which multiple approaches are possible. However, purely technically it does not matter from where the EMS gets the power limitation setpoint. Note also that the EMS is an logical device and can be a separate local device, a software on the smart meter or even in the cloud.
Lets think again at E-mobility.
According to German studies will 80% of EV charging be non-public – in other words behind the meter. These charging processes are somewhat of a black box for the network operators.
Such black boxes can for example be basement garages with multiple charging points. These cause a major increase in local electricity consumption and a stress on the grid!
Without a use case like the power limitation will such locations cause local blackouts. Here the local EMS and its charging management would get a power limit and optimize the charging accordingly. Enables the system to limit the maximum charging current of the EV on each phase depending on the electrical connection. Forecasts can be provided and load curves from the grid side taken into account.
The power limitation use case can be applied on local distribution network level – thus its not limited to single houses. Remember the capabilities of local transformers as I a while ago mentioned. And it can also be applied both to residential and commercial buildings.
With the help of real time consumption data and forecasts for electricity consumption can each level and house be given their individual – and dynamic - power limit.
Considering this individual Pmax, can the local EMS optimize energy consumption, but still comply to the grid requirements. This means: Stable power distribution does not have to be in conflict with local optimization
Furthermore could future energy consumption be influenced – instead of a power limit - by power curves, tarifs or incentives (incentive curves).
Increasing electrification of the mobility and heating domains sets – without any doubt - higher pressure on buildings and their energetic infrastructure to be smart grid „compliant“. This can be reached with local and grid connectivity through EEBUS and the described Pmax use case. For building owners could this e.g. enable participation on flexibility markets and access to lower grid fees.
