Abstract: 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.
