摘要: |
针对目前电网规划方案综合决策问题中客观数据利用不充分和权重分配不合理的问题,提出一种基于改进TOPSIS法和德尔菲—熵权综合权重法相结合的电网规划方案综合决策方法。首先,根据电网规划的发展特点和基本属性,构建了考虑安全、效益、成本和适应性的电网规划SECA综合评价指标体系。其次,应用博弈论模型得到德尔菲—熵权综合权重计算方法。然后,引入绝对理想点以及投影法对TOPSIS法进行改进,并采用改进TOPSIS—德尔菲—熵权组合评价进行电网规划方案评估。最后,利用实际算例验证了该方法的有效性。TOPSIS法与综合权重法相结合充分利用了客观数据全部信息,并且同时具备了TOPSIS法简单实用、可操作性强以及综合权重法主客观均衡的优势。 |

Abstract: |
In allusion to insufficient use of objective data and unreasonable weight assignment in present comprehensive decision-making of power network planning schemes, based on the combination of the improved TOPSIS method with Delphi-entropy weight comprehensive weight calculation method, a comprehensive decision-making method for power network planning schemes is proposed. Firstly, according to the development features and basic attributions of power network planning, a SECA power network planning comprehensive evaluation index system which is based on safety, effectiveness, cost and adaptability is established. Secondly, the Delphi-entropy weight comprehensive weight calculation method based on the game theory model. Then based on absolute ideal points theory and close-degree projection, TOPSIS method is improved. A combinational evaluation method based on improved TOPSIS-Delphi-entropy weight is used to evaluate power network planning schemes. The validity of the proposed method is verified by calculation results of actual case. The method based on the combination of TOPSIS method with the comprehensive weight calculation method can make full use of objective data. It has the advantages of simplicity, practicality and maneuverability, and the weight of this method is reasonable.
