Distributed planning solving method and system of integrated energy system

The invention belongs to the technical field related to comprehensive energy, and provides a distributed planning solving method and system of a comprehensive energy system, the comprehensive energy system is decomposed into an electricity-heat combined subsystem and a natural gas subsystem, and an inner-layer algorithm is adopted in the electricity-heat combined subsystem to realize locating and sizing planning of a distributed photovoltaic power station. The optimal energy supply plan is realized in the natural gas subsystem, only the information at the coupling position is interacted between the two subsystems, the information protection and high-performance calculation solving efficiency of each subsystem are considered, and the high-efficiency solving calculation of the distributed power supply locating and sizing plan and the energy supply of which the information of the comprehensive energy system is not completely shared is realized. 本发明属于综合能源相关技术领域，提出了一种综合能源系统的分布式规划求解方法及系统，将综合能源系统分解为电-热联合子系统和天然气子系统，在
