随着能源危机和环境污染的问题越来越严重,以风电和光伏为代表的可再生能源被大规模地开发利用,电力系统运行稳定性也成为了国内外广泛关注的问题之一。本文首先阐述了自动发电控制(Automatic Generation Control, AGC)的控制原理和控制模式,接着讨论了负荷频率控制(Load Frequency Control, LFC)和经济调度控制(Economic Dispatch Control, EDC)策略的研究现状,通过分析各类方法的优缺点,指出了目前AGC研究存在的一些问题。针对这些问题,进一步阐述了动态AGC控制策略的研究情况,最后对未来AGC领域的发展方向进行了讨论。
英文摘要:
With the energy crisis and environmental pollution becoming more and more serious, renewable energy represented by wind power and photovoltaic has been developed and utilized on a large scale, and the stability of power system operation has also become one of the issues of widespread concern. Firstly, this paper describes the control principle and control mode of AGC, then discusses the research status of LFC and EDC. By analyzing the advantages and disadvantages of various methods, it points out some existing problems in AGC research, and expounds the research situation of dynamic AGC control strategy in order to solve these problems. Finally, this paper discusses the future development direction of AGC field.
