This approach upgrades a group of independent several small users with rigid loads and chaotic behavior, to a large user with a flexible and controlled profile. A central building automation control system (BACS) managing all built-in technical systems and smart appliances may control load minute by minute, shifting in time plannable and controllable ones merging different kinds of load, obtaining a flatter diagram. The authors consider the suggested approach convenient to realize demand side management (DSM) for residential/commercial buildings.

DSM exploits the flexibility of smart appliances and the thermal inertia of the structure, by imposing local and central set-points of heating and cooling systems according to the actual global net load and generation at a given moment. In the present paper, main aspects of the proposed control system are presented and simulations for a given case study with local PV generation are provided. Results show that this approach may lead to power peak reduction up to 20% even in the unfavorable case of combining commercial and residential units. Moreover, full self-consumption of locally generated energy from RES may be achieved.

The suggested model aggregates the users around an electric node in a common microgrid in order to reach up the threshold value of electric power and to get a more virtuous and flexible cumulative load profile. The building (or a group of buildings) represents the natural limit of the aggregation of the electric systems, like in the heating systems. Present proposal is a full electric smart micro grid with heating and domestic hot water generated by a centralized electric heat pump system.

The renewable energy is provided by a photovoltaic field. The authors suggest to control the whole electric demand of the building by exploiting its thermal inertia as an energy storage by forcing both local and central set points of heating and air conditioning systems and time shifting opportunities of smart appliances. A case study is presented.

The paper presents a feasible model of architecture for the technical building systems (TBS) particularly suitable for Nearly Zero Energy Buildings (NZEBs). The suggested model aggregates the users around an electric node, in order to reach up the threshold value of electric power and to get a more virtuous and flexible cumulative load profile. Present proposal is a full electric common smart micro grid with a single point of connection, with heating and domestic hot water generated by a centralized electric heat pump system. The renewable energy is provided by a photovoltaic field connected to the common grid.

A Building Automation Control System operates those electric TBS modulating the global load for a building demand response (DR). The effectiveness of the proposed model consists in exploiting thermal inertia as an energy storage, by forcing both local and central set points of heating and air conditioning systems. The control is based on the integrated and common operation of all users and all systems of the building as one unique “large user”. The integrated management of the grid is operated to control the whole electric demand exploiting the self consumption, avoiding peaks and maintaining a flat load profile.

The suggested micro grid model allows concretely the possibility to realize a building DR with benefits for the end-users in a consumer view point. A study of the effect of these control opportunities on whole electric demand is done by simulation on a case study.

La ricerca si inquadra pertanto nel contesto nazionale ed internazionale, ormai fortemente sentito dalle istituzioni ed anche dai singoli cittadini di promozione dell’uso razionale dell’energia, di miglioramento dei processi di trasformazione, dell’ottimizzazione dei consumi, dell’impiego di fonti alternative di produzione di energia e dell’utilizzo di tecnologie ad alta efficienza per migliorare le condizioni di compatibilità ambientale, in accordo con la politica energetica della Unione Europea.

La finalità è quella di contribuire alla promozione a livello nazionale di “comuni di utenza” con fornitura e gestione unica per aree residenziali e/o commerciali dei servizi come l’energia (elettrica, termica, gas), le comunicazioni (telefono, dati, TV, posta) ed altri (acqua, rifiuti, bike e car sharing ecc.). Particolare attenzione è rivolta all’analisi di fattibilità di soluzioni di microproduzione di energia elettrica con sistemi di produzione combinata di energia elettrica e termica con sistemi cogenerativi e trigenerativi.
