Summary

Building sector accounts for nearly 40% of the global energy consumption. Energy-hub is attached attentions for the energy/cost saving and load shifting of building. In this paper, we proposed a model predicted control (MPC) based demand-side building energy management framework in the energy-hub structure. Simulations in four scenarios with dynamic electricity price were conducted on a building to investigate the energy saving potential under the proposed framework. In scenario 1 and 2, building climate control and economic control were employed to track the indoor temperature setpoint and minimize the cost respectively. In the scenario 3, a typical demand response problem with electric storage device was studied while an additional on-site generation component was considered in scenario 4. The results demonstrate that scenario 2 can achieve 21% cost saving compared to scenario 1. Furthermore, scenario 3 and 4 can achieve nearly 20% and 31% cost saving compared to scenario 2.
