| Abstract: |
| As a key component of an integrated energy system (IES), energy storage can effectively alleviate the problem of
the times between energy production and consumption. Exploiting the benefits of energy storage can improve the
competitiveness of multi-energy systems. This paper proposes a method for day-ahead operation optimization of a
building-level integrated energy system (BIES) considering additional potential benefits of energy storage. Based on
the characteristics of peak-shaving and valley-filling of energy storage, and further consideration of the changes in
the system’s load and real-time electricity price, a model of additional potential benefits of energy storage is
developed. Aiming at the lowest total operating cost, a bi-level optimal operational model for day-ahead operation
of BIES is developed. A case analysis of different dispatch strategies verifies that the addition of the proposed
battery scheduling strategy improves economic operation. The results demonstrate that the model can exploit
energy storage’s potential, further optimize the power output of BIES and reduce the economic cost. |
