Evaluation of Photovoltaic Grid Connection Capacity of Power Grid Considering Seasonal Characteristics of Small Hydropower

Because the regulation capacity of small hydropower is insufficient, the power grid with small hydropower may have different grid connection capacity in the wet season and the dry season, so it is necessary to consider the seasonal characteristics of small hydropower to evaluate the new energy grid connection capacity of the power grid. In this paper, the reverse load rate is selected as the evaluation index to measure the grid connection capacity of the line. Taking the data of G131 line on the West Bank of Nanxi, Jinyun County, Zhejiang Province as an example, the change of the new energy grid connection capacity of the line in one year is evaluated.
