Abstract: Reasonable evaluation on current conditions of smart grid is of vital practical significance to scientific instructions for smart grid planning and construction. Conventional evaluation method for smart grid is mainly static evaluation, which is of single evaluation standard, and without consideration of differentiation factors, which makes the evaluation results not objective and no comparable. A dynamic evaluation method for smart grid, which considers both indicator development differences and regional differences, is proposed in this paper. The method acquires comprehensive evaluation results from two aspects, including to modify evaluation values of properties based on analysis on differentiation degree of each indicator development and to modify weights of properties based on analysis on differentiation of regional development for smart grid. Data of three regions in the latest five years are selected for case study in the paper. Results indicate that compared with traditional methods without consideration of the difference, our method is more objective and reasonable, and is able to effectively find out problems of unbalanced development of power grid.
