Embodiment 1
[0192] Table 1 shows the initial evaluation index value and expected index value of demand-side response resource value in a certain region. The specific index data is taken from the demand-side response measures implemented by a provincial power grid company in 2007, 2008, and 2009. According to the index system formulated above, the data of each index is obtained. The following section will calculate this data Example analysis.
[0193] As shown in Table 1, this model will evaluate the value of demand-side response resources for the power generation side, power grid side, large users, residents, and the whole society, analyze the benefits brought to each participant in demand-side response, and find out the gap link.

Embodiment 2
[0226] Assuming that scientific research results are evaluated, the evaluation index set U={u 1 ,u 2 ,u 3}={academic level, social benefit, economic benefit}, the respective weights are obtained according to the previous steps w={0.3, 0.3, 0.4}
[0227] Determine the comment set as V={V 1 ,V 2 ,V 3 ,V 4}={very good, good, average, bad}
[0228] A single factor evaluation is carried out for each evaluation index of this achievement, such as academic level, 50% of the experts think it is "very good", 30% of the experts think it is "good", and 20% of the experts think it is "average". The single factor evaluation result of the level is R 1 =(0.5, 0.3, 0.2, 0)
[0229] The evaluation results of all factors are

Abstract
The invention discloses a demand side response resource value evaluation method based on a rough set theory, and belongs to the demand side response resource value evaluation technology field. The demand side response resource value evaluation method comprises steps that: a first step, a set constituted by evaluated units is used as a domain; a set constituted by initial evaluation indexes is used as an attribute set A, and the threshold value of the initial evaluation indexes is determined according to related regulations and actual situations; a second step, the initial evaluation index information table of the evaluated units is determined according to the actual values of the initial evaluation indexes; a third step, the initial reduction information table of the initial evaluation indexes of the evaluated units and knowledge A are determined according to definitions. The demand side response resource value evaluation method is advantageous in that the rough set theory is a mathematical tool used for depicting incompleteness and uncertainty, and is capable of effectively analyzing incomplete information, and is used for data reasoning, and then tacit knowledge is discovered, and a potential rule is disclosed. The value evaluation model based on the rough set theory provided by the invention is advantageous in that the model is more comprehensive, and the integrity is stronger.
Description
technical field [0001] The invention relates to the technical field of demand side response resource value evaluation, and specifically provides a demand side response resource value evaluation method based on rough set theory. Background technique [0002] Demand-side response resource value evaluation model based on rough set theory: Rough set theory is a mathematical tool to describe incompleteness and uncertainty. Contained knowledge reveals underlying laws. At present, evaluation methods for resources on the demand side generally have the characteristics of incompleteness and poor integrity. Therefore, the present invention proposes a value evaluation model based on rough set theory, which is more comprehensive and more integrated. [0003] The evaluation methods of demand-side resources generally have the characteristics of incompleteness and poor integrity as follows: [0004] First, there are flaws in the index system, which cannot fully demonstrate the role of dem...
