锁相锁幅控制技术及其在孤立海岛微电网的应用
Amplitude-Phase-Locked-Loop Control Technology and its Application in the Isolated Island Micro Grid
摘要
Abstract
In order to meet the demand for rapid frequency and voltage regulation of micro grid with high proportion of new energy,based on the understanding and recognition of the frequency/voltage dynamics of the new power supply system with high proportion of power electronic equipment,this paper introduces an amplitude-phase-locked-loop structure,and proposes a fast frequency/voltage support method for energy storage based on this structure to participate in the rapid frequency and voltage regulation of isolated micro grid.In the proposed method,the amplitude-phase-locked-loop can provide the frequency/voltage deviation and its differential signal of the power grid.The frequency and voltage regulation method is designed using these four signals to avoid the complex differential operation under the traditional control,while improving the dynamic support performance of the system,so that the energy storage can spontaneously respond to the changes of the system frequency and voltage.Finally,a micro grid model is built in RTDS to verify the effectiveness of the proposed control strategy.关键词
