    As the country proposes the "rural revitalization" strategy in 2017, the rural power grid inevitably faces a new round of upgrading and transformation.How to balance the benefits and risks of rural network investment becomes an important research topic in the future.Based on the analysis of traditional distribution network investment benefits, this paper integrates environmental impact, ancillary services, and rural power grid investment benefits, and proposes a new type of rural power grid investment evaluation system that includes project benefits, management benefits, energy conservation, emission reduction, and valueadded services. At the same time, taking into account factors such as large investment volume and long period of capital recovery, the investment risk evaluation system of rural power grid is introduced. Based on the TOPSISgray correlation degree model, the advantages and disadvantages of the data samples are ranked to reflect the completeness of the evaluation system. In order to reflect the completeness of the evaluation system and the adaptability of the evaluation method, different power supply companies are selected for example verification.In summary, this paper provides power grid investment decision makers with a comparison of different investment schemes based on multiparty risks to better maximize revenue.
