Embodiment Construction

[0076] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0077] Such as figure 1 The illustrated embodiment is a further detailed description of the implementation cases of the present invention in conjunction with the figures below.

[0078] A method for evaluating wind power accommodation capacity of a power system. The power system includes a power load, a high-power battery, a power transmission grid, and several wind power, hydropower, and thermal power generators connected to the power grid; the power load and the high-power battery are respectively connected to the electrical connection to the transmission grid;

[0079] Such as Figure 9 As shown, the method includes the following steps:

[0080] To configure multiple scenarios on the computer:

[0081] Set Scenario 1: E=0, P wn = 0 means the power system with wind power capacity of 0 and no high-power battery connected;

[0082] Set Scenario 2: E =...

Abstract

The invention discloses a wind power absorption capacity assessment method for an electric power system. Random statistical laws of wind power and load are mined based on historical wind power and load data, a wind power absorption capacity assessment model and a solving method are built on the basis, and the method not only can quantize the influence of wind power integration on power generation and peak load regulation capacity of the system, but also can effectively improve wind power absorption capacity by the aid of an energy storage system while meeting long-term planning requirements, so that the problem of difficulty in grid connection and absorption after large-scale wind power development is more effectively solved. The method has the advantage that calculated energy storage capacity Ex or wind power Pwny provides a reliable method and path for planning design and dispatch of the electric power system.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a method for evaluating the wind power accommodation capacity of a power system that can effectively improve the wind power accommodation capacity of the power system. Background technique [0002] Wind power is undergoing a role transition from a small-scale, supplementary power source to a large-scale, important power source. Whether wind power can be connected to the grid after large-scale development and how much wind power the system can absorb after wind power is connected to the grid are the current bottlenecks for the large-scale development of wind power, and are also the focus of attention of the power system dispatching and planning departments. [0003] However, the usual evaluation method of wind power accommodation capacity is to evaluate real-time optimization, and the evaluation results are difficult to provide a reference for the long-term planning ...
