Power grid investment decision optimization based on binomial coefficient and variation coefficient

It is an inevitable trend that investment promotes supply side structural adjustment and demand side response to achieve bilateral power generation. Investment strategies and development paths in key areas of power grid in the future are the focus of power enterprises. Considering the derivative value of power grid investment, this paper proposes a smart grid investment decision evaluation model based on binomial coefficient and variation coefficient. First, the concept, criteria and methods of grid investment derivative value are summarized; Secondly, the smart grid investment derivative value index system is constructed from three aspects: grid investment benefit, grid operation and maintenance effect, and sustainable development value; Based on binomial coefficient method and variation coefficient method,a combination weighting method of subjective and objective fusion is constructed, and dynamic combination factors are adjusted according to different scene requirements to achieve dynamic balance of multiple objectives, reflecting the complementary advantages of subjective and objective methods. At last.we use Curve Comparison Chart and Specific 3D Curve to prove the effectiveness and accuracy of our method.
