Optimal scheduling of renewable energy sources and building energy systems serves as a pivotal strategy for achieving zero carbon emission. However, the coordination of zero carbon building energy systems (ZCBS) is still challenging due to the complicated interactions among multi-energy hybrid storage and the complex coordination between seasonal and daily scheduling. Therefore, this study develops a coordination scheduling approach for ZCBS. An operation model and a seasonal-daily scheduling approach are developed to optimize the operation of hydrogen, geothermal, and water storage devices. The performance of the developed method is demonstrated using numerical case studies. The results show that the ZCBS can be achieved by using renewable energy sources with the system flexibility provided by hydrogen, geothermal, and water storage devices. It is also found that the developed scheduling approach reduces operation costs by more than 43.4% under the same device capacity, compared with existing scheduling approaches.
Key words: zero carbon building energy systems / seasonal-daily scheduling / multi-energy storage / two-stage robust optimization
