Hierarchical evaluation method for competitiveness comparison of multi-distributed energy system

Abstract

The invention discloses a hierarchical evaluation method for competitiveness comparison of a multi-distributed energy system, and the method comprises the following steps: obtaining objective data ofevaluation indexes of the distributed energy system; constructing an original quantitative evaluation data matrix according to the objective data; preprocessing the original quantitative evaluation data matrix and constructing a standardized evaluation index matrix; constructing an evaluation index contribution coefficient matrix for the standardized evaluation index matrix by using an entropy weight method; combining the output evaluation index contribution coefficient and the expert evaluation matrix to obtain a competitiveness result of the distributed energy system; and obtaining a competitiveness sorting result of each energy system according to the competitiveness result. The invention can ensure that the multiple side faces influencing the construction competitiveness of the distributed energy system are reasonably balanced, the quantitative method capable of comprehensively and globally conducting distributed energy system construction decision making is obtained, and the method has high engineering value.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a hierarchical evaluation method for comparing the competitiveness of multi-distributed energy systems. Background technique [0002] In recent years, with the rapid development of the global economy, not only the dependence on electricity is getting higher and higher, but also the requirements for comprehensive utilization of energy are getting higher and higher, which has become a common trend in the development of modern energy industries in all countries in the world. At the same time, it is still arduous for my country to complete the task of reducing greenhouse gas emissions promised to the international community. Based on the above factors, it is determined that the construction of a distributed energy system has become an important means to solve the problem. However, due to the large number of distributed energy systems and the wide variety of application scenarios...

Problems solved by technology

However, due to the large number of distributed energy systems, the wide variety of application scenarios, technical conditions, and economic constraints, it is extremely difficult to conduct a comprehensive and comprehensive evaluation of the construction of a large number of distributed energy systems.

[0003] To evaluate whether the construction of a distributed energy system is competitive, there are several outstanding problems: it is necessary to take into account fairness and rationality; factors affecting competitiveness are divided into two categories: hard factors and soft factors, and there must be appropriate Quantitative methods; most of the existing methods only focus on a certain aspect, such as energy availability, carbon emissions, economy, etc., and a unified evaluation system that can comprehensively consider these aspects is urgently needed
