With the gradual construction and interconnection of regional multi-energy systems, the existing methods of integrated energy system planning need to solve the problem of vertical coordinated planning. 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 are 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. The mathematical model of IBDR considering user satisfaction degree is established. With the goal of minimum planning operating cost, carbon emission cost, and compensation cost, a multi-region integrated energy system coordinated planning that considering IBDR is modeled. Benders decomposition algorithm is used to solve the problem. The model is tested on a multi-region integrated energy system composed of multiple regional systems. Simulation results of two different examples show that IBDR can reduce the capacity requirements of lines and equipment planning and delay the construction of lines, assist to improve the capacity of wind power consumption in regions. Coordinated planning model is economical and environmentally friendly.
