Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0058] Such as figure 1 As shown, a new energy delivery system condenser configuration method based on risk quantitative assessment includes the following steps:

[0059] (1) According to the power system data, determine the typical operation mode and expected fault set. The number of typical operating modes is M, and the number of faults in the expected fault set is F.

[0060] (2) Establish a risk cost assessment model for new energy units off-grid, and calculate the quantitative evaluation indicators for reducing the risk of new energy off-grid by configuring condensers;

[0061] In a specific embodiment, the calculation process of the risk cost assessment index for energy unit off-grid is...

Abstract

The invention discloses a method and device for configuring a new energy delivery system regulator based on risk quantitative assessment, including determining the basic operation mode and expected failure set according to the power system data; establishing a risk cost assessment model for new energy unit off-grid; determining The order of priority for location selection of condenser configuration locations; determine the number of condenser configurations. Based on the risk quantification evaluation theory, the present invention takes into account the unification of safety and economy, quantitatively evaluates the optimal configuration scheme of the new energy delivery system condenser, and provides technical means for improving the reactive power and voltage support capability of the new energy delivery system and promoting the consumption of new energy .

Description

technical field [0001] The invention relates to a method and device for configuring a condenser in a new energy delivery system based on risk quantitative assessment, and belongs to the technical field of electric power automation. Background technique [0002] With the development of new energy power generation technology, it has made important contributions to my country's energy optimization and clean development. However, new energy and other power electronic equipment have low inertia and weak withstand voltage, which also bring challenges to the operation and control of the power grid. As the penetration rate of new energy continues to increase, the characteristics of the power grid have undergone tremendous changes, and the difficulty of security and stability control has increased. At present, in order to prevent new energy units such as wind power and photovoltaics from going off-grid under system AC faults, the converters of new energy units generally have high / lo...
