Quantitative Evaluation of Reserve Projects Based on the Grid Contribution

The comprehensive evaluation of electric construction project is one of the main tasks in the early stage of the project.In order to accurately embody the nature, content, and scale of the reserve projects, a quantitative evaluation method for reserve projects based on the contribution of power grid is proposed in this paper.An evaluation index system and its quantitative calculation method are established, And the optimal weight of each index is determined by utilizing the combination assigning method and particle swarm optimization algorithm.Then the contribution evaluation model of power grid reserve project is constructed based on the contribution and project investment.The dynamic sorting method for power grid reserve projects is determined by analyzing the coupling relationship and decoupling method in the reserve projects.Finally, the distribution network expansion projects in a certain city are taken as an example, and the results are presented to illustrate the usefulness of proposed method.
