The research on adaptability evaluation of wind power integration capacity in power grid considering wind-solar hybrid complementary characteristics and flexible loads interference

As the rapid development of wind power and increasing influencing factors of wind power integration capacity in power grid, the scientific evaluation system of wind power integration capacity is more and more important. In this paper, a complete evaluation system of wind power integration capacity is proposed. After considering the factors such as the plant capacity of power grid, the scale of the power grid, the level of load, the wind-solar complementary characteristics, and the capacity of flexible load, the evaluation index system is defined. By using Delphy method to calculate the weight of the main evaluation index, the final comprehensive evaluation index is obtained. Comprehensive evaluation index can reflect the level and improving space of wind power integration at certain moment. Based on the evaluation system, the on-line evaluation analysis system is designed. The system consists of three parts, data monitoring module, wind power acceptance capability analysis module and adaptive evaluation module. Through the above research, the scientific evaluation and comparison of wind power integration capability between different power grids will be achieve, and the key factors that influence the wind power acceptance will be found, and the healthy development of wind power will be promoted.
