At this year’s ENLIT Europe ESMIG and EEBUS jointly presented their demonstration on end-to-end interoperability. Together with members of both associations, the transmission of a signal along the entire communication chain, from grid operator to end device level, has been presented. Initiated by the grid operator (backend), a power limitation signal was sent via mobile network (DLMS/COSEM) to the smart meter from Landis + Gyr which uses the P1 port to transmit it to the Gateway from Thales. Here, it is converted into EEBUS and sent to the local Energy Manager from TQ which controls connected devices such as heat pump (simulator) and Wallbox accordingly, e.g. by reducing its charging power.

Using a common and widespread smart meter to receive this signal which is then converted into standardised EEBUS communication inside the building, provides an international approach for the integration of e-mobility and heating. This solution can be applied at any market using mobile network based smart meter infrastructure, even in a retrofit approach, and is helping to accelerate the integration of flexible loads.

At its Living Lab in Cologne, the EEBUS initiative offers test services for end-to-end communication. For the German market, for example, a grid test system from Exceeding Solutions (incl. grid control center, GWA, aEMP) that can consider all Smart Meter Gateway variants and control boxes is available for end-to-end system tests.

ESMIG is the European association of smart energy solution providers. Members, ranging from small to multinational companies, develop and manufacture devices, information technologies and services for multi-commodity metering, display and management of energy production and consumption. These products and services cover and connect the entire energy chain, from energy suppliers to distributors, and production at consumer premises in a two-way information highway.

The purpose of EEBUS is the development and standardisation of the communication interface in order to allow for the interconnection between energy management relevant devices as well as corresponding control systems. Special focus is laid on the local interface for grid relevant interconnected devices where, driven by its cross-industry membership structure, EEBUS has especially developed EV, HVAC, white goods and grid related use cases in line with latest market development topics.
