含新能源的电力系统安全性评估
摘要：为解决高比例新能源的接入给电网安全稳定性带来的潜在威胁，采用综合评价法实现新能源电力系统安全性评估和薄弱系统辨识，提供更加全面的系统安全运行决策参考信息。首先，建立新能源电力系统安全性评价指标体系，其次，分别采用决策实验与评价实验室(decision-making trial and evaluation laboratory，DEMATEL)法与反熵权法计算指标的主客观权重；第三，依据相对熵思想计算综合权重；最后，以改进的IEEE-118母线不同渗透率新能源电力系统为参考，采用多准则妥协解排序法(Više-Kriterijumska Optimizacija I Kompromisno Rešenje，VIKOR)进行综合评估与优劣排列分析和灵敏度验证。不同新能源渗透率电力系统安全性排序为：10 %>40 %>20 %>30 %>50 %，其评估结果可在实际工程中参考应用。
Abstract:To deal with the potential threat to the security and stability of power grid caused by high proportion of grid-connected new energy, a comprehensive evaluation method was utilized to realize the security evaluation and the identification of weak power grid to provide a more comprehensive reference information for the decision of system secure operation. Firstly, a security evaluation index system for the power grid containing new energy was established. Secondly, the decision-making trial and evaluation laboratory (abbr. DEMATEL) method and the anti-entropy weight (abbr. AEW) method were used to calculate the subjective and the objective weights of the index. Thirdly, based on the thought of relative entropy the comprehensive weight was calculated. Finally, taking the modified IEEE-118 bus new energy power system with different permeability as a reference, and by use of Više-Kriterijumska Optimizacija I Kompromisno Rešenje (abbr. VIKOR) method the comprehensive evaluation, the ranking analysis on the advantages and disadvantages as well as the verification of sensitivity were conducted. The security ranking of new energy power systems with different permeabilities is as following: 10% >40% >20% >30% >50%, and such an evaluation results can be available for reference and utilized in practical engineering.
