EEBUS
SOLUTIONS
All EEBUS Use Cases are aligned with each other and thus allow for a variety of business models, while avoiding conflicting interests and chaos at the grid connection of a building. Our EEBUS solutions provide an overview of how these use cases can be combined and used best and for which purpose. Real customer value is achieved by combining these solutions.
Power Limitation
The transmission of power limitations for consumption and feed-in ensures compliance with physical and grid-initiated constraints at the grid connection point (GCP) and thus supports a stable local grid operation. This solution enables transparency and control at the GCP.
End-user devices can be continuously operated within the power limitations given by the Distribution System Operator (DSO). This allows energy-related and manufacturer-specific business models to develop, without endangering the grid situation.
The limitation signal is sent to the EMS, which adjusts the energy flow of connected devices accordingly and aligned with customer preferences. In the absence of an EMS, a single device receives and reacts to the signal directly.
TLS encrypted transport in combination with national requirements for the gateway at the GCP ensures data protection and IT security.
System follows country-specific requirements. In Germany the highly secure intelligent Metering System (compliant with BSI TR-03109-compliant) combines the Smart Meter Gateway with a smart meter. Here, the SMGW enables MGCP Use Case.
METER
The Meter is providing the buildings’ total power consumption to the EMS or the DSO.
*In Germany the MGCP measured values are transmitted through the Smart Meter Gateway.
Gateway
Enables secure communication between DSO and External Market Participants and the EMS while applying/considering country-specific requirements (on security and functionality).
EMS
The EMS receives power limitation from the DSO via the Gateway and dispatches available power to the corresponding devices according to the cost and comfort related preferences set by the end-user.
CONTROLLABLE DEVICES
The controllable devices may be connected to an EMS (in case of two or more controllable devices) or directly to the gateway, which allocates the available power capacity to the connected device(s). Devices can continue to be operated within the limits set by the DSO and in compliance to end-user preferences.
Tariff management
Time of use tariffs enable incentive-based load management. They can be used e.g. to optimise local grid load via dynamic grid fees or to optimise cost-effective operation of energy devices based on electricity market prices (e.g. EEX).
The tariff information is sent from the DSO or Energy Provider (ESP) to the EMS which adjusts the overall power consumption of connected devices. Depending on the end users’ preferences, the EMS offers incentives to devices while considering the base load and possible grid constrains given by the DSO. Devices, such as EVs or heat pumps, will calculate their power consumption schedules by taking advantage of their flexibility and making them available to the EMS. This enables cost-optimised operation of the devices or revenue-optimised PV feed-in.
Market mechanism, such as dynamic tariffs, can continuously been applied, even in times of grid constraints.

Preventive Capacity Allocation
For DSO
This solution enables proactive and preventive capacity management at the grid connection point (GCP). The DSO is able to allocate capacity ranges (via Power envelopes) for the entire premise at GCP to prevent foreseeable grid congestion scenarios in the low-voltage grid.
For a more precise power envelope, the DSO might receive a power demand forecast of the building, beforehand. Inside the building, the EMS takes care of adjusting energy flows of connected devices within the boundaries of the power envelope.

For TSO
The Energy Service Provider (ESP) can use this solution for balancing services for the Transmission System Operator (TSO) to avoid cross-regional grid congestion. Single devices can be aggregated to a larger power pool and operated in a grid-supportive way.
To do so, the ESP might request the power demand forecast of the building (via the gateway or directly from the asset) and sends back a power schedule envelope to the asset, which adjusts its power consumption or feed- in accordingly. This power schedule is also provided to the EMS which considers it in the overall energy management of the building.

Self-Consumption Optimisation
This solution allows end users to benefit from reduced energy costs for the operation of their devices while improving their ecological footprint. EEBUS enables devices to communicate their current and forecasted power consumption or production. The EMS influences the power consumption of devices as well as PV feed-in in such a way that all demands will be scheduled underneath the PV production curve. In presence of energy storage capability such as stationary battery system or bidirectional EV, PV surplus energy may be stored temporarily to be provided to the building after sun set. The EMS also considers device specific constraints, e.g. time of departure or energy demand of the EV.
