Fuzzy AHP-based comprehensive evaluation for smart grid in energy internet systems

Reliability validation is an important research field in smart grid and involves the comprehensive consideration of various evaluation factors. Because it is difficult to accurately define the indicators of qualitative analysis, the fuzzy comprehensive evaluation method is introduced to evaluate each index and obtain reasonable, comprehensive and effective evaluation results. A novel model evaluation method called fuzzy analytic hierarchy process (FAHP) is proposed for smart grid in the area of energy internet, and it considers the interaction among the indices. The solution estimates the index weight through the analytic hierarchy process and builds the evaluation model using the fuzzy comprehensive evaluation method based on the hierarchy process to assess the performance of the evaluation model with fuzziness. Then, the effectiveness of the method for smart grid is verified by numerical examples. The fuzzy method proposed will provide an alternative technique for assessing different aspects of interaction in smart grid.
