Power grid enterprises are the backbone of promoting clean and low-carbon energy transformation, playing an important role in achieving carbon peak and carbon neutrality. It is very necessary to audit the implementation of the "dual carbon" work of power grid enterprises, in order to better implement the national "dual carbon" policy and serve the development of the national economy. The risk assessment of "dual carbon" audit in power grid enterprises is multiple-attribute group decision-making (MAGDM). In this study, in light with projection measure technique and bidirectional projection measure technique, four forms of projection measure technique with q-rung orthopair fuzzy sets (q-ROFSs) are conducted. Then, two weighed projection techniques are conducted to manage the MAGDM. Finally, a numerical example for risk assessment of "dual carbon" audit in power grid enterprises and comparative analysis is utilized to verify the developed techniques. The major contribution of this research is constructed: (1) entropy technique is implemented to determine the weight values in line with score number (SN) and accuracy number (AN); (2) two weighed projection techniques are implemented to put forward MAGDM with q-ROFSs; (3) the numerical example for risk assessment of "dual carbon" audit in power grid enterprises is implemented to show the two weighed projection techniques under q-ROFSs; and (4) comparative studies are constructed with existing techniques.
电网企业是推动能源清洁低碳转型的主力军，在实现碳达峰、碳中和目标中发挥着重要作用。对电网企业“双碳”工作落实情况进行审计，对于更好地贯彻国家“双碳”政策、服务国民经济发展十分必要。电网企业“双碳”审计风险评估属于多属性群决策（MAGDM）问题。本文基于投影测度技术和双向投影测度技术，构建了四种q阶正交对模糊集（q-ROFSs）投影测度技术。然后，运用两种加权投影技术处理多属性群决策问题。最后，通过电网企业“双碳”审计风险评估数值算例及对比分析，验证所提方法的有效性。本研究的主要贡献在于：（1）运用熵权法，结合得分函数（SN）和精度函数（AN）确定权重；（2）运用两种加权投影技术，提出基于q-ROFSs的多属性群决策方法；（3）通过电网企业“双碳”审计风险评估数值算例，展示基于q-ROFSs的两种加权投影技术；（4）与现有方法进行对比研究。
