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 optimal operation of the building as a whole. Distribution system operators are reluctant in allowing renewable energy in the grid as it engages investments into the grid and increases costs for its correct and secure operation.

Distribution system operators are interested in introducing coordinated energy exchange with buildings through dynamically changing conditions, e.g. via optimized hourly price profiles.. 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 at the same time it will result in optimized costs on the grid side whereas grid and buildings will also interact through exchanging energy and prices data. This is expected to motivate installation of distributed storages in both buildings and grids 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 of the energy management tool 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.
