Abstract：Under the"carbon peaking and carbon neutrality goals",the novel power system urgently requires grid planning to show strong adaptability to the randomness and volatility of high proportion of renewable energy.However,in addition to grid planning technology and economic benefit indicators,decision makers'attitude towards planning risk and profit and loss is also an important factor that will affect the evaluation results of grid planning adaptability.Therefore,this paper introduces the Improved Cumulative Prospect Theory(ICPT)to represent the multiple decision-making psychology of decision makers,and constructs an adaptability evaluation system of power grid planning scheme for novel power system.First,an evaluation index system is established based on the adaptive needs of the grid planning for novel power system,and optimal weights are derived using the Artemisinin Optimization-Projection Pursuit combination weighting method.Second,ICPT is adopted to improve the calculation method of the distance between the evaluation program and the positive and negative ideal programs in the GRA and TOPSIS.Then,based on the Shapley value to combine evaluation results of ICPT-GRA and ICPT-TOPSIS,an improved combined evaluation model based on ICPT is established.Finally,the power grid planning scheme of three regions of a certain province is taken as an example to carry out evaluation analysis and verify the effectiveness of the proposed evaluation system.
