Energy Efficiency Evaluation

At present, there is a lack of regional comprehensive energy multi-dimensional evaluation system and calculation of different quality energy in the energy efficiency evaluation of regional integrated energy system. Based on this, this article carries out research on multi-dimensional energy efficiency evaluation index system and evaluation methods. First, this article form quantifiable evaluation indicators from the aspects of energy supply subsystem energy efficiency, energy conversion subsystem energy efficiency, grid energy efficiency, economic benefits and social benefits, and clarify the calculation methods of each evaluation indicator. Then this article calculate the indicator combination weight. Finally, a multi-dimensional energy efficiency assessment method for a regional integrated energy system is proposed, and an example is used to prove the effectiveness of the method.

Discrete Manufacturing

The difficulty in the energy efficiency analysis of discrete manufacturing system is the lack of evaluation index system. In this paper, a novel evaluation index system with three layers and 10 indexes was presented to analyze the overall energy consumption level of the discrete manufacturing system. Then, with the consideration of the difficulties in directly obtaining machine energy efficiency, a prediction method based on recursive variable forgetting factor identification was put forward to calculate it. Furthermore, a comprehensive quantitative evaluation method of rough set and attribute hierarchical model was designed based on the index structure to evaluate the energy efficiency level. Finally, an experiment was used to illustrate the effectiveness of our evaluation index system and method.

Regional energy efficiency evaluation stands for the analysis of regional energy efficiency whose aim is to figure out the low– and high– efficient parts in energy consumption, providing most economic suggestions to improve energy efficiency. Based on the energy balance sheet, this paper decomposed the energy efficiency of one entire region into different sub-regional values and then got the energy efficiency index of each sub-region through standardized treatment. Further, the overall energy efficiency index was calculated out through weighting to lay the foundation of energy efficiency analysis and energy saving potential evaluation. Besides, this paper analyzed and compared the 2010 and 2006 energy efficiency data of China (including 30 provincial-level administrative regions) with a result that the evaluation index system of regional energy efficiency could satisfy the energy saving and managing demands, like location and analysis of regional energy efficiency level .

Currently, energy-saving building is a hot topic in society, which is also generally recognized as the most direct and effective way with the greatest potential for energy saving in the industry when the energy problem has become increasingly urgent today. At present, the domestic scholars less focus on rural residential energy saving, so the energy efficiency assessment on countryside buildings is still a relatively new field. This paper introduced existing energy-saving building assessment system at home and abroad through referring to the domestic and overseas existing assessment system, combining the characteristics of energy efficiency of rural residential buildings in China, constructed the energy-saving evaluation index system of rural residential buildings. Expert opinions and analytic hierarchy process (AHP) were used to determine the index weight, and the rationality of the evaluation system was determined by an empirical analysis case.

Energy Efficiency Evaluation

Thermal power industry in China is facing energyshortage , but now there is a lack of a comprehensive energy efficiency evaluation system to promote the energy efficiency ,The energy efficiency evaluation for steam turbine and auxiliary system fills this gap. On account of the fuzziness and randomness of the evaluation process, we propose the AHM-F combination evaluation method.It not only evaluted the energy efficiency level of the steam turbine and auxiliary system,but also point out the direction for further improving of energy efficiency level. The scientificalness and effectiveness of the proposed method is verfied by the example analysis of the 600MW unit in a power plant.
