Abstract

Abstract: Wind power cluster, such as inland mountain wind power and lake wind power, has the characteristics of wide-range distribution and low power capacity of single wind farm. A comprehensive evaluation indexes framework is established for transmission planning of wind power cluster based on economy, security and adaptability of power grid. And then, with a comprehensive consideration of subjective weights and the objective weights, the moment estimation theory-based optimal combination weighting method is used to determine the optimal combination weight of each index, and an improved gray relational analysis method is proposed through combination of gray correlation analysis and cosine sorting method, to evaluate each scheme more accurately and reasonably. At last, the proposed evaluation indexes framework and evaluation method are applied to the wind power cluster transmission planning in Hunan Province, which has verified their effectiveness and feasibility.

Key words: wind power cluster, transmission planning, evaluation index framework, moment estimation theory, improved gray relational analysis
