摘　　要：为解决微网柔性并网系统中并行接口电路的运行效率低、动态性能差的问题,采用基于PI或PID的双向LLC谐振电路混合控制,实现零转电压到输入和输出整流器,管电流闭合显着提高了变换器的动态性能,与最优电源相比,显着降低了运算的复杂度,提高了运算的传输周期。采用状态平面法是从概念层面用信息来描述双向LLC谐振电路的控制和特性,在此基础上开发了一个电子存储接口控制系统,其模拟显示了这一点,基于PI或PID的双向LLC谐振电路储能设备接口电路的理论分析和共享混合管理,其效率是准确的和动态运行的重要性,保证了微网柔性并网系统的运行性能。In order to solve the problems of low operating efficiency and poor dynamic performance of the parallel interface circuit in the microgrid flexible grid-connected system,considering the hybrid control of the bidirectional LLC resonant circuit based on PI or PID,the zero-turn voltage to the input and output rectifiers is realized,The tube current closing significantly improves the dynamic performance of the converter.Compared with the optimal power supply,it significantly reduces the complexity of the operation and improves the transmission cycle of the operation.Using the state plane method is to use information from a conceptual level to describe the control and characteristics of the two-way LLC resonant circuit.On this basis,an electronic storage interface control system has been developed,and its simulation shows this.Based on the theoretical analysis and shared hybrid management of the PI or PIDbased bidirectional LLC resonant circuit energy storage device interface circuit,its efficiency is accurate and dynamic operation The importance of ensuring the operation performance of the microgrid flexible grid-connected system.
