  • Demand side response (DSR) will be an important scheme for a secure, sustainable and affordable electricity system. Buildings will play more important roles in DSR in the future energy system as they consume much energy. Studies on system planning (SP) for buildings give the optimal energy system configuration. However, these studies usually do not examine the real operational conditions of optimally designed system. On the other hand, studies on the energy management system (EMS) usually assume capacities of the components in the energy system are pre-determined. It is unclear whether the decided system from SP can meet the system demands when subject to real operational conditions in EMS. This study aims to fill in this research gap. The optimization results from SP and the operation results from EMS were compared in a case study, which consists of photovoltaic panels, heat pump, electrical heater and hot water tank. Robust optimization was used in EMS to consider prediction uncertainties. The results show that the optimally designed system can meet the electricity and heat demands. The real operation cost from EMS is slightly higher (less than 1%) than the optimization results from SP. It should be noted that this work only considers a particular case study. Nevertheless, more cases and various operational scenarios should be considered in future works.
