| 摘要: |
| 电能质量综合评估对实施有效的电能质量管控和电力市场环境下合理的依质定价至关重要。根据评估指标、评估权重及评估模型三方面的特性进行了分类，概述了电能质量综合评估的研究现状。在此基础上，总结了现有方法所存在的问题:无法适应不同应用需求、尚未针对长时间尺度进行评估、未综合考虑评估结果的治理成本和经济效益、较少考虑暂稳态指标融合等。最后指出考虑经济效益的评估方法、DG并网条件下的综合评估、数据驱动的电能质量评估及能源互联网电能质量综合评估是未来此领域可能的研究方向。 |

| Abstract: |
| The comprehensive assessment of power quality is essential for the implementation of effective power quality control and reasonable pricing in the power market environment. According to the characteristics of evaluation index, evaluation weight and evaluation model, this paper classifies and summarizes the research status of power quality comprehensive evaluation. On this basis, it summarizes the problems in existing methods including it cannot adapt to different application requirements, has not been evaluated long-term scales, has not considered the governance costs and economic benefits of the evaluation results comprehensively, and has less consideration of the integration of transient steady-state indicators. Finally, this paper points out that the evaluation method considering economic benefits, the comprehensive evaluation under DG grid-connected conditions, the data-driven power quality assessment and the comprehensive evaluation of energy internet power quality are the future research directions in this field.
