Abstract

The invention discloses a method for quantitatively analyzing intermittent energy synergistic effect based on a time domain, and belongs to the technical field of new energy power-generation grid-connection. The method comprises the following steps: analyzing intermittent energy long-term synergistic effect from two time scales of years-months and days based on related coefficients; determining an intermittent energy daily output fluctuation characteristic classification method based on fuzzy classification; computing two intermittent energy synergistic effect indexes: the intermittent energy synergistic effect related coefficient and an intermittent energy synergistic effect fluctuation index; analyzing intermittent energy years-months and days scale synergistic effect according to the intermittent energy synergistic effect related coefficient; and analyzing intermittent energy short-term synergistic effect based on the intermittent energy synergistic effect fluctuation index. The synergistic effects of the intermittent energies are analyzed from the time scales in different levels to determine the relevance and complementary between the intermittent energies, and the theoretical basis and guidance are provided for the power network planning containing a high permeability intermittent energy regional power grid.

Description

technical field

[0001] The invention belongs to the technical field of new energy synergy, and in particular relates to a method for quantitatively analyzing the synergistic effect of intermittent energy based on time domain. Background technique

[0002] In a complex power system containing a variety of new energy sources, due to the differences in resource characteristics, geographical environment, climate and other factors of different types of new energy electric fields, when they are incorporated into the system, the overall output power characteristics will affect each other. The fluctuation of output power will bring different hidden dangers to industrial and agricultural production.

[0003] The characteristic of reduced overall volatility is called the synergy effect. In fact, the synergy effect is the cluster effect of different resource types. The analysis method of synergy effect is similar to cluster effect. In view of the fact that wind power develops most ra...
