Embodiment Construction
[0036] A method for quickly determining the importance of the power grid risk management and control dimension proposed by the present invention specifically includes the following steps:
[0037] (1) Establish a function model based on the best power grid risk management and control effect and the greatest power grid risk reduction:
[0038]
[0039] In the formula: γ and β are the weighting factors of the objective function, which are set according to the importance of the objective function, γ+β=1; ΔR 1 (j loss ) The objective function of reducing the risk of the power grid in stages, i is the number of risk items in the power grid in the statistical period, α i In order to reduce the effectiveness coefficient of the risk control dimension in stages, R i is the risk assessment value of the power grid before risk control; maxΔR 2 (y loss ) is the permanent risk reduction objective function, R i ′ is the risk assessment value of the power grid after the implementation...

The invention provides a method for rapidly determining the importance in the risk control dimension of power grid. The method comprises the following steps that (1) a mathematic model aimed at optimizing the risk control effect of the power grid and minimizing the risk of the power grid is established by combining the risk control dimension of the power grid; (2) an influence factor matter-element set and a node state matter-element set based on the model are established by utilizing an extension correlation function as a solution means rather than solving an object mathematical model of the risk control effect of the power grid, and the importance in the risk control dimension of the power grid is calculated rapidly on the basis of a solution method of the extension correlation function of the model; and (3) according to different power-grid states, importance in the risk control dimension of the power grid is ordered, and an execution principle based on the importance degrees in the risk control dimension of the power grid is formed. Risk control is guided and realized effectively, the risk of the power grid is reduced, and the intrinsic safety of the power grid is improved.
Description
technical field [0001] The invention belongs to the technical field of power system operation and control, and in particular relates to a method capable of quickly determining the importance of a power grid risk management and control dimension. Background technique [0002] Traditional power grid risk management and control often distributes management and control requirements to various units and departments for implementation, without analyzing the importance of the management and control dimension. The resulting risk management and control levels are not clear, the focus is not prominent, and the focus of risk management and control investment resources is not prominent. , not maximizing performance. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the above-mentioned prior art, and provide a method that can quickly determine the importance of the power grid risk management and control dimension. By establishing ...
