摘要: 为研究微电网中的三端口变换器功率协调控制,提出了一种基于麻雀搜索算法的 三端口变换器功率协调控制策略。首先,对一种新型的隔离型三端口变换器进行拓扑分析,并 推导三端口变换器的等效电路模型和功率传输公式;然后,建立了三端口变换器的小信号模型, 设计了基于麻雀搜索算法的功率协调控制策略;随后,通过仿真软件初步验证了麻雀算法相较 于传统 PI控制的优势;最后,通过 RTLAB实验平台验证了所提策略的可行性。实验结果表 明:三端口变换器在不同运行场景下能稳定、平滑且有效地切换工况,实现功率协调控制。

Abstract: This study proposes a sparrow search algorithm-based power coordination control method for three-port converters in microgrids. Firstly, a novel isolated three-port converter is topologically analyzed, and an equivalent circuit model is established, followed by the derivation of the basic working principles and power transmission formulas of three-port converters. Secondly, a small-signal model of the three-port converter is developed, and a power coordination control strategy based on the sparrow search algorithm is designed. Subsequently, the superiority of the sparrow algorithm over traditional PI control is preliminarily verified through simulation circuits. Finally, the feasibility of the proposed strategy is validated through the RT-LAB experimental platform. The experimental results show that the three-port converter can operate stably, switch operating conditions according to external conditions, and achieve power coordination control.
