Building sector accounts for nearly 40% of the global energy consumption. As an efficient way to manage buildings energy, energy-hub are attached much attentions.
To investigate the energy saving potential of a commercial building, this paper proposes an approach based on the economic model predictive control (EMPC) in three scenarios under energy-hub framework.
First, EMPC is applied to minimize the building energy costs with variant electricity price and comfort range. Next, demand response problem with heat/electricity storage device is introduced. Finally, an additional generation unit is considered.
The simulation experiment is carried out in heating season for one week. The results show that first scene can achieve 28% energy costs reduction than original operation. Compared to the first scenario, there is 14% and 17% reduction in the scenario two and three respectively. In general, EMPC can achieve good performance in building energy management under energy-hub framework.
