3Smart - Smart Building – Smart Grid – Smart City

Current tendencies in the Danube Region to integration of energy-efficiency  measures and renewable energy  are not followed by their adequate interactions to enable cost-optimal operation of the building as a whole. Distribution system operators are reluctant in allowing additional capacities of intermittent renewable energy in the grid as they engage investments into the grid and a costly reserve for secure operation. Distribution system operators are interested in introducing coordinated energy exchange with prosumers through dynamically changing conditions, e.g. via optimized price profiles for netto energy exchange. Currently neither of the countries in the Danube Region has regulatory/technology framework developed for inception of building-grid cross-spanning energy management schemes.
The main objective of the 3Smart project is to provide a technological and legislative setup for cross-spanning energy management of buildings, grids and major city infrastructures in the Danube Region. It will provide optimal economical value to energy-efficiency and renewable energy  investment in the building and optimized costs on the grid side as well as motivate installation of distributed storages for improving energy security in the Danube Region.

The project outputs are:

(i) Modular software tool for energy management on building and distribution grid side,

(ii) Five pilot actions in different Danube Region countries including buildings and grids with intersected technology/regulatory setups and

(iii) Strategy to enable city-wide energy management and related regulatory barriers removal in the Danube Region.

Main target groups are regulatory energy agencies/ministries (related to updating regulatory set-up), distribution system operators and suppliers (related to improving grid effectiveness), local authorities and regional energy agencies (related to reducing return-on-investment for investments in energy-efficiency and renewable energy); R&D institutions (related to possibly new modular extensions to the developed energy management, for specific configurations of buildings and grids).
Major innovative moment is in vertical two-way synchronization through all the modules via simple interfaces to attain optimal operation of the buildings and the grid, and easy modules add-on to the existing already deployed automation equipment.
