School comprehensive energy system technology economy evaluation method and system

Abstract

The invention relates to a school comprehensive energy system technical economy evaluation method and system, and the method comprises the following steps: constructing a technical economy evaluationindex system of a to-be-evaluated project, wherein the evaluation index system comprises 10 indexes in the aspects of technology, economy and environment, 8 indexes are quantitative indexes, and 2 indexes are qualitative indexes; inputting the evaluation indexes into an established technical economy evaluation model, wherein the technical economy evaluation model comprises the weight and evaluation method of each index; and determining the weight by adopting an order relation analysis method and an anti-entropy weight method, and evaluating the technical economy of the school comprehensive energy system by applying a TOPSIS method of introducing the weight. The school comprehensive energy system technology economy evaluation method and system can scientifically and reasonably evaluate theschool comprehensive energy technology economy, and have high use value.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy system evaluation, and in particular relates to a method and system for technical and economical evaluation of a school comprehensive energy system. Background technique [0002] Energy consumption and environmental issues are two major problems and challenges faced by rapid economic development, especially in developing countries. With the gradual strengthening of people's awareness of energy saving and environmental protection, the integrated energy system has become the key to solving energy and environmental problems. In recent years, new energy technologies such as photovoltaic power generation, wind power generation, and heat pumps have been widely used, making the integrated energy system complex and diverse. Techno-economic evaluation is the main means to measure the advanced nature of comprehensive energy technology research results and the generalizability of engineering ex...

Problems solved by technology

[0003] The integrated energy system has many characteristics. At present, the research on the technical and economical evaluation of the integrated energy system has just started. At present, the technical and economical evaluation of the integrated energy system mostly uses indicators such as investment cost, net present value, and investment payback period, and does not consider other indirect The impact of factors on the technical economy of the system, such as technical factors, environmental factors, evaluation indicators are relatively single, most of the evaluation system selects quantitative indicators, lack of consideration of qualitative indicators

In the evaluation process, the subjectivity and objectivity of the evaluation cannot be considered comprehensively, and only the subjective weight is considered, and it is difficult to avoid the deviation caused by human factors; recognized

Some methods of combining subjective and objective weights require consistency checks and excessive sensitivity to cause index failures
