摘要:

目的 随着我国新型电力系统的不断发展,光伏、风电等新能源大规模并网,同时,智能化控制设备与非线性负载等不断增加,导致电能质量问题越来越复杂。为了提升整个电网的供电品质、实现电网的经济运行和优质高效发展,对电能质量进行科学、合理的量化评估至关重要。 方法 从电能质量评估指标、赋权方法以及评估模型3个方面出发,对电能质量综合评估方法进行系统的归纳和比较,概述了电能质量综合评估方法的研究现状;并在此基础上,总结了现有的各种电能质量综合评估方法的不足及尚需解决的问题,并对未来此领域可能开展的研究方向进行展望。 结论 目前国内外对于电能质量综合评估的研究虽然已经取得了许多成果,然而各方法有其各自的优点和不足,且在该领域内仍有一系列被忽视的重要问题需要解决。

Abstract:

Objectives With the continuous development of China's new power system, there is a growing integration of new energy sources such as photovoltaic and wind power into the grid. However, this integration has also led to an increase in intelligent control equipment and nonlinear loads, resulting in more complex power quality issues. In order to enhance the power supply quality of the entire power grid and achieve economic operation and efficient development, it is crucial to conduct a scientific and rational quantitative evaluation of power quality. Methods Starting from three aspects of power quality evaluation indicators, weighting methods and evaluation models, the comprehensive power quality evaluation methods were systematically summarized and compared, and the research status of comprehensive power quality evaluation methods was summarized. On this basis, the shortcomings and problems that need to be solved of various existing comprehensive power quality assessment methods were summarized, and the possible research directions in this field were prospected. Conclusions Although many results have been achieved in the research on comprehensive evaluation of power quality at home and abroad, each method has its own advantages and disadvantages, there are still a series of important neglected problems that need to be solved in this field.
