Smart Grid is a complex scientific issue of the world’s power systems. It is a further development trend in the future. Currently, many developed countries such as European and American power grid enterprises are actively promoting innovation and managing change, Smart grid is one of the most important objectives of the enterprises. China has also presented the object of coustructiong a strong smart grid, the intelligent development of power grid in the further is not only a country’s development goals, but also the goal of the regional power grid. Therefore, it needs to evaluate the regional power grid’s intelligence development level.The evaluation of regional power grid intelligent level has an important practical and theoretical significance, a scientific evaluation can promote smart grid development healthly, and it can provide a technical support for network development and decision making. This will not only benefit the construction of power itself, but also make the entire power industry construction and development economic. It also helps social harmony and stability for sustainable development.This paper studys the regional power grid intelligence development evaluation based on the actual situation. Firstly, the factors of intelligent development of regional power and influence are analyzed. Combined with smart grid development related concepts, evaluation features, and intelligent power grid index system principles, ideas and from the interactive, self-healing, security, economic, clean, energy-saving and efficient characteristics, the national smart grid intelligence development level is studied. Secondly, the methods on the grid evaluation are summarized, the evaluation scope of these methods is also given. Based on the regional power grid index system construction principles and the indicatiors normalized method, an evaluation index system of regional grid is created from the safety, economy, good, coordination, and intelligence five aspects. And the main work is as follows:(1) The establishment of a regional network intelligent evaluation index system. Index system including security, economy, quality, coordination and efficiency in five areas, indicator system established by the experiments shows that science can contribute to the development of smart grid, smart grid development for the firm to provide technical support and decision-making basis, not only conducive to building strong and smart grid itself, but also to the entire power industry construction and development, sound economic development and social harmony and stability for sustainable development.(2) The establishment of a regional network of intelligent level of development based on combined weights of the hierarchical optimization of complex evaluation of optimization model. Because of different data characteristics of security, economy, good, coordination and efficiency, needs assessment of targeted select the appropriate method of its evaluation, including security aspects of neural network model is selected, the economy in terms of choice DEA DEA is, excellent in terms of TOPSIS method is used, coordination with the FEAHP methods, and efficient device selection method is the SVM series, and then the evaluation of all aspects of analysis, the overall results of the evaluation comprehensive evaluation of all aspects of weight in terms of a subjective weight to determine the objective weight and the combination of AHP-Entropy method, the corresponding weights and the evaluation of all aspects of the final results of the evaluation results can be obtained.(3) For the actual conditions on the regional power grid development of intelligent computing horizontal and vertical analysis. Horizontal is selected by the North China Power Grid, China Power Grid, Northeast Power Grid, Central China Power Grid and the Northwest Power Grid in 2009 the five regional evaluation of the empirical analysis of the data, the corresponding order situation. Is a region of longitudinal use 2003-2008 assessment data in empirical analysis. Results from the evaluation found that the level of development in the region should focus on intelligent network to develop those indicators, in order to provide the basis for the corresponding proposal.(4) The development of regional power grid intelligent proposals and programs. On the basis of the above, combined with the results of the regional grid computing development of regional power grid, summarize all aspects of the analysis to identify the level of the key aspects of network development, key indicators, and five on the grid from future development reasonable suggestions.Finally, the conclusion of this article, summed up in this part of the research article, and looks ahead the future research.
