针对双碳背景下新型电力负荷管理系统通信方式单一以及业务与通信技术适配性差等问题，构建了含本地通信和远程通信的新型电力负荷管理系统多域通信架构，并分析支撑该架构的关键技术。其次，根据差异化业务类型与通信需求，构建了业务与通信技术适配性评价体系，并提出了一种基于模糊层次分析法-融合熵权CRITIC-灰色关联逼近理想解排序法的通信方式适配方法，以实现差异化业务与多域通信技术适配性分析。由算例分析得，所提架构与适配算法为新型电力负荷管理系统业务进行多域通信技术的选择提供了有效的理论基础和解决方案。

Under the dual carbon background, a multi-domain communication architecture was constructed to address issues such as a single communication mode and poor adaptability between business and communication technology in the new power load management system. The key supporting technologies of this architecture were comprehensively analyzed. Additionally, an adaptability evaluation system for business and communication technology was developed based on varying business types and their specific communication requirements. A communication technology adaptation method was proposed, employing the fuzzy analytic hierarchy process (FAHP), the CRITIC method, and grey relational analysis-technique for order preference by similarity to an ideal solution (GRA-TOPSIS). The proposed method facilitates the analysis of adaptability between differentiated business requirements and multi-domain communication technologies. The analysis of case studies indicates that the proposed architecture and the adaptation method offer an effective theoretical basis and solution for selecting multi-domain communication technology for the new power load management system business.
