Analysis on Sustainable Performance of Wind Power by Using MCDM Method

Abstract

Wind power can be an efficient way to alleviate energy shortage and environmental pollution, and to realize sustainable development in terms of energy generation. The sustainability assessment of a wind power project among its alternatives is a complex task that cannot be solely simplified to environmental or economic feasibility and requires the consideration of its technological and social aspects as well as other circumstances. This paper proposes a novel method for selecting the most sustainable wind power projects. The method is based on multi-criteria decision-making (mCDm) techniques; the analytic hierarchy process and entropy weight method combined with determining the weights of evaluation indexes, and an innovative index-weight optimization method based on the Lagrange conditioned extreme value. The TOpSIS is applied to rank wind project alternatives considering the system functionality and proportionality. The results indicated that the calculated wind power’s sustainable level can provide a reference point for the planning and operation of the wind project; the results thus have a certain value with regard to both their theoretical significance and practical application in engineering.
