Research on benefit distribution mode of regional integrated energy system considering both direct and indirect benefits

A co-benefits assessment index system is developed for the introduction of a regional integrated energy system (RIES). Following which, by analyzing the interest demands of each stakeholder and determining the beneficiaries of each unit benefit, the initial benefit distribution model based on attribution relationship is established. According to the networked relationship of stakeholders, a fair and reasonable cost sharing mechanism for RIES is established. On this basis, the benefit–cost (B/C) analysis is carried out from various stakeholders to evaluate the commercial feasibility. According to the simulation results of a numerical study, the project as a whole and all stakeholders have B/C values greater than 1 to coordinate and balance related issues such as system income distribution according to the designed benefit distribution mechanism. In this way, the win-win situation of overall interests and individual interests can be realized.
