Problems solved by technology

Regarding the risk of voltage sag loss, the object, time, place and degree of loss are uncertain. Once it occurs, it will bring huge economic losses to sensitive users
The degree of satisfaction of the risk of voltage sag loss is low, and the risk of voltage sag loss is weakly insurable. Since the insurance mechanism requires the partici...

Embodiment 1

[0049] Such as figure 1 The shown method for confirming a voltage sag insurance mechanism for sensitive power users includes the following steps:

[0050] A. The decision-making scheme of the four decision-making subjects of users, insurance institutions, power departments, and governmentb j Based on the decision-making attributes and decision-making attributes, the multi-attribute decision-making matrix A of decision-making subjects for different decision-making schemes is constructed k , and the multi-attribute decision matrix A k Transformed into a normalized matrix R k ; The decision-making attributes include insurance premiums, loss instant compensation, risk exposure, and net income;

[0051] B. Calculate the decision attribute weight;

[0052] C. Calculate the decision-making scheme b of all decision-making subjects j decision value;

[0053] D. Sorting of decision values ​​to determine the most feasible decision-making scheme.

[0054] On the basis of clarifying...

Embodiment 2

[0056] Based on the principles of the foregoing embodiments, this embodiment discloses a specific embodiment.

[0057] Stakeholders of voltage sag loss risk events include users, insurance institutions, power departments and governments, which are decision-making subjectsa k , k=1, 2, 3, 4. The user does not participate in the insurance mechanism, the market-oriented type, the market-cooperative type and the market-guided type are different decision-making schemes, that is, decision-making scheme b j , j=1, 2, 3, 4. The establishment of the insurance mechanism mainly relies on the joint participation of the insured and the insurer. The user is the insured, while the insurance institution, the power department, and the government are all insurers; and the input of the compensation amount, so the user loss is a bridge connecting the insured party and the insured party. The user's loss depends on the sag duration, depth, frequency and user anti-disturbance ability. It is the m...

Embodiment 3

[0090] In this embodiment, user L of three high-end manufacturing enterprises in a high-tech park 1 -L 3 Take the method as an example.

[0091] Users L1-L3 of three high-end manufacturing enterprises in a high-tech park conduct field survey statistics and analysis. During 2007-2014, users L1-L3 monitored the voltage sag data and statistical loss data of the 10kV bus as attached figure 2 , 3 , 4, 5 shown. In existing research at home and abroad, figure 2 , 3 4. This kind of map is also called sag density map, which is mainly used to present a large amount of power quality investigation data clearly and clearly, so as to facilitate quantitative evaluation of its power quality characteristics. attached figure 2 , 3 4. The X-axis in 4 represents the duration of a single sag; the Y-axis represents the magnitude of a single sag; the Z-axis represents the period from 2007 to 2014 when the user encountered a sag and the duration was within a given range. drop times. as a...

Abstract

The invention discloses a voltage sag insurance mechanism confirming method for a sensitive power user, and the method comprises the following steps: constructing a multi-attribute decision matrix ofa decision making subject for a decision theme on the basis of the decision scheme and decision attributes of the decision making subject, and converting the multi-attribute decision matrix into a standard matrix, wherein the decision attributes comprise insurance premium, net income, payment amount, and risk taking degree; calculating decision attribute weights; calculating decision values of alldecision makers on the decision scheme; sorting the decision values to determine the most feasible decision theme. The two-stage multi-target decision making method is employed, and the method integrates multiple types of attribute information. The preference degree of the scheme is optimized, and the attribute weights are obtained, thereby solving a problem that the subjectivity of the weights is high. The method achieves the evaluation of the preference degree of each subject for different mechanisms, and achieves the concluding and unifying of the scattered evaluation information of all subjects. The clear and high-feasible voltage sag insurance mechanism improves the insurability, improves the recognition degree of each side for the insurance mechanism, reduces the loss of each side,and improves the feasibility.

Description

technical field [0001] The invention relates to the technical field of power system high-quality power and power market analysis, in particular to a method for confirming a voltage sag insurance mechanism for sensitive power users. Background technique [0002] With the expansion of industrial scale and the development of science and technology, more and more high-tech electronic and electrical equipment and processes sensitive to voltage sags are connected to the power grid, causing users to face huge losses and risks. Under normal circumstances, power companies and users solve the problem of voltage sag by installing customized power equipment and improving the quality of power grid power supply. However, these measures have the problems of high investment cost and long payback period. However, different users have different requirements for power quality, and have different anti-disturbance capabilities for voltage sags, resulting in a power quality level that cannot sati...
