Safety Evaluation of Smart Grid based on AHP-Entropy Method

It has become a realistic choice to develop smart grid actively to meet the electricity demand for load centers, especially in China. In the current period of rapid development, in order to effectively measure the safety level of smart grid, to compare power grid safety among different regions or within the same region at different times, in this paper, smart grid safety evaluation index system is proposed from six aspects such as structural safety of transmission network, structural safety of distribution network, high-efficient system and equipment support, operational safety and stability, adequacy and Resilience. With the thought of combined evaluation, this paper uses AHP-Entropy method to evaluate the safety of smart grid. Finally, an empirical study shows this method is effective.
