Research On Evaluation Method Of Grid Investment Benefit

As the overall investment in power grid increases yearly, how to improve the efficiency of power grid input -output has become a hot issue. This paper introduces a new grid input-output benefit evaluation method by looking for the corresponding relationship between grid stock asset investment, incremental asset investment and output benefit. Meanwhile, factors such as the time value of funds and the full life cycle cost have been taken into consideration. Based on the grid input-output benefit evaluation index system, a comprehensive evaluation model for grid input-output benefit is established in order to analyse the grid input-output benefit. The method overcomes the problem of non-corresponding between input and output in the traditional method and achieves to reflect the stock assets of the grid precisely.
