电力系统低频振荡是现代电网发展进程中一个亟待解决的问题,随着以风电和光伏为主的新能源发电渗透率越来越高,传统阻尼控制手段将难以独立应对电力系统运行特性出现的新变化.为充分发掘新能源发电在参与阻尼低频振荡方面的潜力,需要对新能源的阻尼控制展开研究.该文整理了无阻尼控制新能源发电对低频振荡的影响的研究现状,概述了当前各类阻尼控制器的阻尼控制原理,然后分控制器设计和控制结构设计两大部分对新能源阻尼控制的研究现状做了归纳和总结.在设计控制器之前,首先需要解决控制器的安装位置、控制输入-输出的选择和配对等控制结构问题,工程经验、留数法和几何测度法等是较常采用的控制结构设计方法.相比电力系统稳定器、高压直流输电系统和柔性交流输电系统等传统阻尼装置,新能源阻尼控制器对鲁棒性和自适应性的要求更为严苛,因此该文着重对最优控制、自适应控制、鲁棒控制和模糊逻辑控制等先进控制进行了介绍.“,”The low frequency oscillation of power system is an urgent problem to be solved in the development of modern power system. As the penetration of new energy power generation, especially wind and photovoltaic power generation, is increasing, the traditional damping control means will be difficult to independently deal with new changes of power system operating characteristics. In order to fully explore the potential of new energy power generation in damping low frequency oscillation, it is necessary to study the damping control of new energy power generation. In this paper, the research status of damping control of new energy power generation on low frequency oscillation is summarized. The damping control principles of various damping controllers are sketched. Then the research on the damping control of the new energy damping control is made in two parts: the controller design and the control structure design. The status quo is summarized and summarized. Before the step of controller design, it is necessary to solve problems of control structure, such as placement of actuators, control input-output selection and pairing. Compared with conventional damping devices such as power system stabilizer, high voltage DC and flexible AC transmission system, the new energy damping controller has more rigorous requirements on robustness and adaptability, so this paper focuses on advanced control, such as optimal control, adaptive control, robust control, fuzzy logic control, etc.
