Problems solved by technology
However, there are problems in these two types of methods. The method of weighting according to the degree of relative importance reflects the subjective intuition of the decision-maker, but is easily affected by the lack of relevant experience and knowledge of the decision-maker; the method of weighting according to the degree of data dispersion is completely based on mathematics. Theories and methods, the calculation results are objective and accurate, but completely ignore the influence of subjective factors of decision makers, which is inconsistent with the original intention of many comprehensive evaluation processes

Embodiment Construction
[0061] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, and therefore are only examples, and cannot be used to limit the protection scope of the present invention.
[0062] figure 1 It is the implementation flow diagram of the method for confirming the evaluation index weight of the transmission network planning scheme provided by the present invention, which specifically includes the following steps:
[0063] In step S101, each index is assigned a value according to the importance of each index data in the index system, and the weight coefficient p of index j is obtained j .
[0064] In step S102, according to the degree of dispersion of each index data in the index system, each index is assigned a value to obtain the weight coefficient q of index j j .
[0065] In s...

The invention relates to the technical field of power transmission network planning, and provides a power transmission network planning scheme evaluation index weight confirmation method and system, and the method comprises the steps: carrying out the assignment of each index according to the importance degree of each index data in an index system, and obtaining a weight coefficient pj of an indexj; Assigning each index according to the discrete degree of each index data in the index system to obtain a weight coefficient qj of the index j; And calculating a comprehensive weight coefficient ofthe index j according to the calculated weight coefficient pj and weight coefficient qj of the index j and a comprehensive weight calculation formula so as to confirm the weight of the index in the index system, reflect subjective information of a decision maker and objective information of data distribution, and provide a guarantee for power grid planning scheme evaluation.
Description
technical field [0001] The invention belongs to the technical field of transmission network planning, and in particular relates to a method and system for confirming the evaluation index weight of a transmission network planning scheme. Background technique [0002] The goal and requirement of the comprehensive evaluation of the transmission network planning scheme is to comprehensively and quantitatively examine the satisfaction of the safety, economy, environmental protection and other requirements of the transmission network planning schemes and the degree of adaptation to the level of national economic and social development. Provide the basis for the most reasonable planning scheme. Safety is the first element considered in power grid planning. Power grid planning must ensure reliable supply of loads and have certain accident prevention capabilities. At the same time, the power grid planning scheme needs to take into account the requirements of economy and environmenta...
