Optimal Operation of Integrated Energy Systems Considering Coupling Characteristics: Models and Quantitative Analysis
摘要
The Integrated Energy System (IES) has the characteristic of multi-energy coupling. However, the coupling degree and benefits between heterogeneous energy sources have not yet been quantitatively analyzed. In this context, firstly, an IES structure that couples electrical energy, thermal energy, and natural gas energy is constructed in this paper, the definitions including energy coupling degree are proposed for quantitative analysis of the coupling of IES systems are proposed. Secondly, an IES optimal operation model with the goal of minimizing total cost is established. Finally, based on a 71-node testing system, the effectiveness of the proposed model and method is verified.
