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.
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.
The Energy Provider may provide variable tariffs based on electricity market prices to adjust the consumption to the availability of energy. The DSO can provide dynamic transmission fees as a preventive measure to avoid overload scenarios, by influencing the overall consumption or feed-in of buildings according to the local grid situation.
The EMS receives the time of use tariff, directly from the DSO or Energy Provider, through a gateway or cloud service and offers the energy through domain specific incentive-tables to the controllable devices. The devices will choose the best price option according to their energy demands and provide their consumption plans to the EMS.
EVSE/EV + HVAC
The controllable device (with significant load) is connected to the EMS to receive the tariff information. The device will choose the best price option according to its’ energy demand and provide its consumption/charging plan to the EMS.
The battery is connected to an EMS and incentivised to charge or discharge according to current price of electricity.
WHITE GOOD DEVICE
The white good device receives a smart start signal from the EMS in case of ow price of electricity.
