【摘要】：目前，能源与环境问题依然不容乐观,人们开始追求低污染、低排放、低消耗的经济增长方式。在此背景下,在调整能源结构、推动新能源产业发展中发挥重要作用将会是消耗大量化石能源的电力行业。智能电网是未来电网的发展方向，承担着巨大的节能减排任务，，它最大的特征之一就是“清洁高效、坚强可靠”，能够有效促进低碳电力经济发展。本文针对智能电网低碳效益的评价体系进行了深入的研究，在分析了国内外智能电网评价内容、评价方法等相关研究现状的基础上，对我国智能电网的内涵、目标以及实施的战略意义进行了研究。然后分别从智能电网的发、输、配、用电及调度等角度考虑其能够实现的低碳效益，构建了科学全面的智能电网低碳评价指标体系，并提出了以组合评价理论为基础的评价方法。并以云模型改进的层次分析方法确定主观权重，熵权法确定客观权重相结合为基本脉络，针对智能电网低碳指标体系的特点设计了将熵权法、云模型改进的层次分析法、改进理想点法、改进灰色关联度法、主成分分析法等评价方法相结合的基于组合评价理论的智能电网低碳效益评价模型，进而使智能电网的低碳效益评价能够更加科学、可靠、准确及有效。本文以南方某省“十二五”规划为基础依据，将设计好的评价指标体系及评价模型应用于该省智能电网的低碳效益评价。实证分析表明，本指标体系对未来区域智能电网低碳发展的进一步改进和完善有着重要的指导意义，也对未来智能电网的重点发展方向及评价智能电网所产生的社会、经济效益等有着重要的参考价值。
[Abstract]:At present, energy and environment problems are still not optimistic, people began to pursue low pollution, low emissions, low consumption of economic growth. In this context, the electric power industry which consumes a lot of fossil energy will play an important role in adjusting the energy structure and promoting the development of new energy industry. Smart grid is the development direction of power grid in the future, and it undertakes a huge task of energy saving and emission reduction. One of its biggest characteristics is "clean, efficient, strong and reliable", which can effectively promote the development of low-carbon power economy. In this paper, the evaluation system of low carbon benefit of smart grid is deeply studied, and the connotation of smart grid in our country is analyzed based on the analysis of domestic and foreign intelligent grid evaluation content, evaluation methods and other related research status. The goal and the strategic significance of implementation are studied. Then the low carbon benefit of smart grid is considered from the aspects of smart grid generation, transmission, distribution, electricity consumption and dispatching, and a scientific and comprehensive evaluation index system of low carbon for smart grid is constructed. An evaluation method based on combination evaluation theory is put forward. Based on the cloud model improved AHP method to determine the subjective weight and the entropy weight method to determine the objective weight as the basic context, aiming at the characteristics of the low carbon index system of smart grid, the entropy weight method and the improved analytic hierarchy process of cloud model are designed. The low carbon benefit evaluation model of smart grid based on combination evaluation theory is improved by improving the ideal point method, grey correlation degree method and principal component analysis method, so that the low carbon benefit evaluation of smart grid can be more scientific and reliable. Accurate and effective. Based on the twelfth five-year plan of a southern province, this paper applies the designed evaluation index system and evaluation model to the low carbon benefit evaluation of the province's smart grid. The empirical analysis shows that this index system has important guiding significance for the further improvement and improvement of the future regional smart grid low-carbon development, but also for the future smart grid development direction and evaluation of the smart grid generated by the society. Economic benefit has important reference value.
