description | In this study, considering the characteristics of multi-energy coupling and multi-level interconnection, a bi-level steady-state physical model is developed. Both decomposed and unified solution methods are employed for the energy flow calculation under the bi-level and multi-energy coupling structure. A numerical study is executed to examine the validity of the algorithms. In addition, the load change within the microgrid and the system operation state under both on-grid and off-grid modes are examined. According to the simulation results, compared with the unified solution method, the decomposed method has faster solution speed and higher data privacy protection, and is more adaptive to the further expansion of the scale of the interconnected microgrids. The microgrids can realize energy interaction and energy mutual aid through grid-connecting operation or inter-network interconnection. |
