Frequency modulation control method suitable for optical storage power generation system

The invention discloses a frequency modulation control method suitable for an optical storage power generation system. On the basis of a traditional optical storage power generation system, the change of the power grid frequency is introduced into an energy storage control strategy, frequency modulation is carried out by utilizing the energy storage when the power grid frequency changes, and a certain effect of phase-locked loop optimization on the power grid frequency modulation is verified by optimizing the phase-locked loop. According to the invention, a traditional optical storage structure is further developed and utilized, so that the optical storage device not only has the capacity of peak clipping and valley filling, but also has the function of frequency modulation, and is simple in structure and universal. 本发明公开了一种适用于光储发电系统的调频控制方法。本发明在传统光储发电系统的基础上，将电网频率的变化引入储能的控制策略中，实现在电网频率变化时利用储能进行调频，并通过优化锁相环，验证了锁相环优化对电网调频具有一定的效果。本发明在传统光储的结构上进一步开发和利用，使其不仅具有削峰填谷的能力，还具有调频的功能，本发明结构简单，具有普适性。
