Comprehensive evaluation of low-carbon power grid operation level based on cooperative game and improved ideal solution
Led by the goal of carbon peaking and carbon neutral in energy field of China,the power grid is showing a low-carbon development trend,and it is necessary to build a more comprehensive evaluation system for the comprehensive evaluation of the low-carbon power grid operation level.A comprehensive evaluation method of low-carbon power grid operation level based on cooperative game and improved ideal solution is proposed.First,considering the influencing factors of low-carbon power grid operation,a multi-level low-carbon power grid operation level evaluation index system including safety and reliability,economy,flexibility,adaptability and environmental protection is proposed.Secondly,the optimal combination weighting method based on cooperative game is used to determine the combined weight of each indicator,and an exponential variable weight function is used to adjust the combination weight.Finally,taking the actual grid operation data of a certain area as an example,the improved ideal solution method is used to comprehensively evaluate the operation level.The results show that the proposed method can accurately and reasonably evaluate the operation level of low-carbon power grids,which is helpful to guide the planning and decision-making of low-carbon power grids.
