With the gradual construction and interconnection of regional multi-energy systems, integrated energy system planning methods need to solve the problem of coordinated planning. Now many planning methods only consider single-region, centralized energy supply methods, which will cause problems such as equipment redundancy and low reliability. Therefore, incentive-based demand response (IBDR) measures were introduced to study multi-region integrated energy system coordinated planning that takes energy interaction between regions into account. This paper uses the energy hub to describe the energy relationship within the integrated energy system. Secondly, the IBDR considering user satisfaction degree is modeled. With the goal of minimum planning operating cost, carbon emission cost, and compensation cost, a multi-region integrated energy system collaboration that considering IBDR is modeled. Benders was used to solve the problem. The model was tested on a multi-region integrated energy system composed of multiple regional systems. Simulation results show that IBDR can reduce the capacity requirements of lines and equipment planning and delay the line's construction, improve the capacity of wind power consumption in regions. Coordinated planning model is economical and environmentally friendly.
