Description

technical field [0001] The invention belongs to the field of distributed energy planning, and in particular relates to an energy optimization configuration method for a multi-energy complementary park considering power-to-gas planning. Background technique [0002] The increasing demand for energy and the continuous access of distributed generation (DG) have had a certain impact on the energy allocation of traditional multi-energy complementary parks. The reasonable configuration of its comprehensive energy supply center can not only reduce the loss in the energy transmission process, absorb more DG, but also realize the coordinated planning of electricity / heat / cold multi-energy flow. However, for the current research on the optimal configuration of multi-energy complementary systems, most of them focus on a certain type of equipment or a few certain types of equipment to form the system structure, and do not fully consider the diversity of system equipment types, and the ob...
