电网规划方案组合评价模型构建与应用

针对电网规划的特点,需要兼顾综合考虑电网规划方案的财务效益、技术经济、可靠性以及对环境的影响等,分别采用层次分析评价、熵值评价法等主、客观单一评价模型构建出基于信息熵原理的组合评价模型,对单模型评价结果进行综合,确保评价出最优的控制方案;实证研究表明:现实组合评价模型可有效地获取各单一评价模型的优点,提高电网规划方案优选的实用性,为电网规划方案的优选评价问题提供了一条新的研究思路。

Construction of Combinational Evaluation Model for Power Grid Planning and Its Application

According to the characteristics of power grid plan, fiscal benefit, technical economy, reliability, its effect on the environment and so on need to be comprehensively considered, as a result, combinational evaluation model is constructed based on information entropy principle and by using simple subjective and objective evaluation model such as hierarchy analytic evaluation, entropy evaluation and so on respectively, and then the results from simple model evaluation are comprehensively analyzed to ensure optimal control plan from the evaluation. Empirical research results show that the combinational evaluation model can effectively obtain the advantages of each evaluation model and promote the practicability of power grid plan selection and provide a new idea for the choosing and evaluating of power grid plan.
