摘要：This paper studies the input-output model considering microgrid and multi-load microgrid. Combined with the new power reform, the investment strategy of the distribution network is analyzed and evaluated. The input model considers depreciation of fixed assets, operation and maintenance fees, and electricity purchase costs. The output model considers the benefits of distribution services and the benefits of electricity sales. On this basis, the uncertain factors in grid investment are studied, and the probability distribution function is constructed. The "incremental method" is used to analyze the influence of uncertain factors on the evaluation index of the reform scheme, and the most sensitive factor is obtained. Finally, the case study shows that the input-output model can better reflect the evaluation indicators of the transformation plan and provide decision-making basis for the grid investment transformation plan.
