Wind power plant active support control capability evaluation method based on grading evaluation

The invention discloses a grading evaluation wind power plant active support control capability evaluation method comprising the following steps: determining a first-level index of the wind power plant active support control capability, and constructing a second-level index based on the first-level index; determining the weight of the second-level index and solving an evaluation value corresponding to each first-level index; constructing a three-dimensional improved radar map, and introducing an evaluation function based on the characteristics of the three-dimensional improved radar map to calculate an active support control capability evaluation value of the wind power plant; and wind power plant active support control capability grading evaluation is realized. According to the method, the active support capability of the wind power plant can be evaluated more comprehensively, the credibility is better, and power grid dispatching and wind power enterprises can be better promoted to know performance condition
