Transmission investment evaluation based on Hierarchy-gray correlation model

Abstract

It's the must link for power grid companies to investment evaluation. In the traditional evaluation process, the decision-making based on the original score or a similar program is earlier, which exists the problem of simple theoretical support shortfall. This paper fully considers the power grid construction investment in the process of various factors, and makes the actual demand for standards, building a set of hierarchical structure with three indicators of the index system, on this basis, analyzing Hierarchy Process and gray correlation method, designing the evaluation model, and making a example to prove the evaluation model validated.
