摘　　要：针对目前输电网规划方案综合决策问题中信息不完全和权重主观性强的问题,提出了基于熵权法和灰色关联分析法相结合的输电网规划方案综合决策方法。该方法首先应用熵权法确定各评价指标的客观权重,克服了原始灰色关联中指标平权和专家赋值的不足;然后采用改进的灰色关联分析法得出最优方案。熵权法与灰色关联分析法相结合充分利用了各指标的全部信息,且充分发挥了灰色关联适合具有一定灰度小样本事件的优势。仿真算例验证了该方法的有效性。In allusion to incomplete information and strong subjectivity of index weights in present comprehensive deci- sion-making of power transmission network planning, based on the combination of entropy weight with grey correlation analy- sis a comprehensive decision-making method for transmission network planning is proposed. Firstly, the entropy weight is used to determine objective weights of evaluation indices to remedy the insufficiency of average index weight and experts assigned index weight in original grey correlation; then the optimal scheme is obtained by improved grey correlation analysis. The combination of entropy weight with grey correla- tion analysis can fully utilize overall information of each index and give full play to the superiority of grey correlation that it is suitable for small sample events with a certain gray level. The effectiveness of the proposed method is verified by simulation results of IEEE Garver-6 system.
