摘要: 含孤网的电力系统黑启动方案评估是一个模糊多准则决策问题。提出并建立了孤网黑启动评价指标体系,把粗糙熵技术用于黑启动方案评估。先用三角模糊数量化定性指标,并对连续属性进行离散化处理;再利用粗糙集理论对冗余或不重要属性进行约简。给出了利用粗糙熵求取黑启动评价指标权重的方法,最后利用理想点法得出方案优劣排序。此方法合理融合定量和定性指标,考虑了指标间的关联及冗余,实际算例证明了此方法的有效性和可行性。

Abstract: Assessment of black-start plans for power system with isolated islands is an issue of fuzzy multi-criteria. An assessment index architecture for black-start plans of power systems with isolated islands was established, in which rough entropy was introduced, the qualitative indices were quantified by using triangular fuzzy number, the continuous attributes were discretized, and the redundant or unimportant attributes were reduced by using rough sets theory. As the result, a method to obtain the weight of assessment indices for black-start plans was conducted, which can be used with the ideal point method to give the sequence of black-start plans for power systems with isolated islands. This method mixes the quantitative and qualitative indexes together reasonably, and takes account of the relevance and redundancy between indexes. A practical example proves its effectiveness and feasibility.
