Abstract:The selection of project management mode for the battery energy storage station on grid slide, as an emerging construction project, is related to whether the expected social and economic benefits could be got. an evaluation index system of management model selection for the battery energy storage station on grid slide is constructed according to the industry development stage and the characteristics of the project, a model is established using the TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution), gray correlation theory and vector projection method for the selection of project management mode in the battery energy storage station on grid slide. In order to overcome the shortageSobjectivenessSof the subjectiveSweightingSmethod, suchSasSexpertSevaluationSetc, the IFS (Intuitionistic Fuzzy Sets) was used to determine the weight of the evaluation index. A major province of electricity in china is taken as example to calculate and analysis, and the result is consistent with the engineeringSpractice. The method is proved to be effectiveSandSapplicable.
