Abstract

The invention discloses a new energy station internal frequency modulation instruction decomposition model construction method. According to the method, the output scene of the new energy field station is predicted, the output scene is reduced through a fast forward reduction method, a new energy field station participation energy and frequency modulation market strategy optimization model is constructed based on the reduced output scene, and the optimal declaration capacity of electric energy and frequency modulation of the new energy field station is determined. Meanwhile, a frequency modulation instruction decomposition model in the new energy field station is established. The method effectively promotes the new energy station to reduce the output fluctuation, actively participates in the frequency modulation market, reduces the operation cost of the power grid, and improves the operation flexibility of the power grid.

Description
