Abstract: In this paper, a new method of the Accurate Investment of Power Grid (AIPG) Based on Full Life Cycle Input-output Benefit is proposed, clearly putting forward a comprehensive benefit evaluation index system of power grid in different application scenarios. First, according to the evaluation method, different scenarios are compared and selected and the feasible project is obtained. Secondly, under the condition that the investment capability is constrained, the feasible scheme is optimized, screened and sorted, and the investment plan of the grid project is determined to realize the accurate investment of the grid development. Finally, this paper combines the empirical analysis of Jiangsu power grid to optimize, select and sort the project, and demonstrates the feasibility and practical value of the evaluation system. The method is of great significance to the development of investment efficiency and efficiency of the grid, and makes up for the gap and deficiency of the current investment in precision investment.
