自适应下垂与前馈控制提升孤岛微电网功率分配

OpenAlex

该文提出一种面向孤岛微电网并网成形逆变器的自适应下垂与前馈控制方法,用于改善瞬态功率分配和解耦性能。文章认为,尽管控制器相同,线路阻抗等电路差异仍会导致瞬态功率共享表现较差,因此先建立PCC动态小信号模型,再设计自适应解耦控制器。文中称该方法可补偿线路阻抗电压跌落、削弱电路耦合并保持稳态增益一致,已通过仿真和实验验证。

证据说明:后续效果取决于该控制策略在不同线路阻抗和运行点下的适配能力,以及仿真结果能否在实际微电网中稳定复现。

三端口DC-DC变换器提出灵活功率分配控制

OpenAlex

该文针对三重有源桥(TAB)DC-DC变换器提出一种灵活功率分配控制策略,并通过三端口双有源桥(DAB)改造以降低端口间耦合。之所以这样做,是因为传统TAB在三组电感强耦合下,调制计算和基于模型的设计都较困难,难以实现快速动态响应。文章还给出稳定性分析和PI参数,并用仿真与小型硬件原型验证方案有效性与准确性。

证据说明:后续表现主要取决于该控制策略在不同工况下的稳定性验证结果,以及小型硬件原型之外的进一步实验是否能复现快速动态响应。

电力电子变换器阻抗模型保留同步动态

OpenAlex

该文提出一种扩展阻抗模型,显式保留电力电子变换器的同步动态,并将输入、输出变量独立保留,以便更精细地分析微电网稳定性问题。文章认为,随着高比例可再生能源、电网构网和跟网逆变器与同步发电机并存,宽频动态耦合更复杂,传统模型难以分离关键环节。该模型无需引入冗余即可保持可扩展性,并已通过仿真和实验验证,有助于识别弱阻尼模态和不稳定根因。

证据说明:后续应用效果取决于该模型在不同控制环节下的可迁移性,以及能否继续通过实验验证其对弱阻尼模态定位的准确度。

动态电价下配电网分布式功率管理优化

OpenAlex

该研究提出了考虑动态电价的配电网分布式事件触发最优功率管理方法。之所以这样设计,是为了在分布式场景下协调功率分配,并适应电价随时间变化带来的调度需求。文中给出的信息显示,论文发表于2024年9月1日,题为《Distributed event-triggered optimal power management of distribution networks considering dynamic tariff》,直接指向配电网优化调度与动态计价机制的结合。

证据说明:后续应用效果主要取决于事件触发机制在实际配电网中的执行稳定性,以及动态电价信号能否被调度与控制环节及时接收。
