Integrating modified Delphi method with fuzzy AHP for optimal power substation location selection

摘要

Evaluation and selection of power substation location is an important strategic decision-making problem for both public and private sector. The multi-dimensional,multicriteria nature of the power substation location problem limits the usefulness of any particular single objective model. Studies have shown that electromagnetic radiations emanating from the high voltage lines and substations,pose serious adverse health consequences to living beings. In this study,social,technological,economical,environmental and site characteristics factors and sub-criteria,have been derived to make the optimal power substation location selection decision more realistic and effectual. In this paper,an improved and more appropriate power substation location evaluation and selection model has been developed by integrating modified Delphi method with fuzzy analytic hierarchy process (FAHP). A numerical example is presented to show applicability and performance of the proposed methodology followed by a sensitivity analysis to discuss and explain the results.
