Problems solved by technology

These devices and methods usually do not distinguish the differences in thermal and electrical system characteristics, and adopt a unified modeling method; or do not consider the network relationship, and simplify the process according to the energy flow relationship, which often cannot effectively reflect the difference in electricity and heat transmission characteristics and network loss. It is difficult to meet the accuracy requirements of the model for an integrated energy system containing a complex network
