Abstract

The invention provides an energy storage system random configuration method considering wind power uncertainty, a terminal and a storage medium, and the method comprises the steps: setting parametersaccording to the wind energy distribution of a region where the terminal is located; simulating random wind speed by utilizing two-parameter Weibull distribution, setting scenes, and enabling the probability of each scene to be equal; reducing the number of the original scenes into a plurality of representative scenes through a fast forward calculation method in a scene reduction algorithm; if thereduced number of scenes is greater than the set reserved number of scenes, circularly reducing the scenes until the set number of scenes is reached, and converting the reduced wind speed scene intoa wind power scene by utilizing a wind speed and wind power output relational expression; solving the model based on a sequential quadratic programming method; and if the solving result meets the constraint condition, outputting the solved values of the energy storage system installation node, the capacity and the target function. A representative wind speed scene is reserved by using the scene reduction algorithm, so that the trouble of analyzing and calculating each scene is avoided, and the calculation complexity is reduced.

Description

technical field [0001] The present invention relates to the technical field of wind power, in particular to a method for random configuration of an energy storage system, a terminal and a storage medium in consideration of the uncertainty of wind power. Background technique [0002] With the consumption of primary energy and the intensification of environmental pollution, in order to reduce the use of fossil fuels and promote the sustainable development of the power system, wind energy, as a non-polluting renewable energy, has begun to be connected to the grid on a large scale. However, wind power output is random and uncontrollable, and it will have a great impact on system operation after being connected to the grid. On the one hand, how to consider the uncertainty of wind power output poses a challenge to grid planning. cost, and the response speed is slow, it is difficult to adapt to the fluctuation of wind power output; on the other hand, wind power with high penetratio...
