Abstract

In order to solve the problem of the connection between the initial planning scheme and the later system operation in the long-term planning, based on the energy consumption characteristics of agglomeration-promotion-type rural areas, a multi-stage planning model for integrated energy systems in such areas was established using a village in the Guanzhong Plain as a case study, considering optimal construction sequencing, and the results show that： 1） Compared to the single-phase planning approach, the multi-phase planning approach, which takes into account the optimal construction timing, resulted in a 38.9% increase in the residual value of the energy system equipment, a 5% reduction in operating costs, a 4.5% reduction in life cycle costs, and an increase in the environmental benefits of the system.2） The increase of the energy load highlights the superiority of the multi-stage planning method, and the rural areas with a fast development speed are especially suitable for adopting the multi-stage method for the planning of the integrated energy system.3） After adopting the multi-stage planning method, the life cycle cost of the energy systems in the typical representative regions of severe cold, cold, hot-summer and cold-winter, and hot-summer and warm-winter decreased by 5.01%, 4.51%, 4.30%, and 0.21% respectively compared with the single-stage planning situation. If the multi-stage planning method is adopted for the energy system planning in severe cold, cold, and hot-summer and cold-winter regions, the economic benefits of the system can be significantly improved, while the improvement in economic benefits in hot-summer and warm-winter regions is limited.
