Optimal operation of energy-efficiency building: A robust optimization approach

The intermittent nature of renewable energy sources and inaccurate load forecast bring up great uncertainties in the operation of power systems, which consequently increases the risk of inadequate energy supply especially during the peak load hours. This paper proposes a robust optimization model taking into account the randomness of electric and thermal loads, as well as solar power production. The robust energy supply is determined from various energy sources including electric grid, battery, and combined heat and power (CHP) with boiler unit. The operation of energy-efficiency building becomes more robust against these uncertainties. The simulation results demonstrate the effectiveness of the CHP unit and battery in alleviating the influence of uncertainties in the operation of the energy-efficiency building.
