Transient Global Inertia Sharing and Steady-state Frequency/Voltage Recovery Control Strategy for Hybrid AC/DC/DS Microgrid
混合交流(alternating current,AC)/直流(direct current,DC)/分布式储能(distributed energy storage,DS)微电网通过整合交流、直流及分布式储能子网,可有效提升偏远地区的能源可及性与供电稳定性.然而,传统微电网结构单一,多聚焦于交流频率或直流母线电压的单一调节.相比之下,混合微电网中频率和电压相互耦合,必须同时调节频率和电压,防止其出现暂态深度跌落和稳态大幅偏移.针对上述问题,该文提出面向混合微电网的暂态全局惯量互济与稳态频率/电压自主恢复控制策略,实现子网间惯量多边传导和频率/电压稳态自主恢复;此外,该文构建混合微电网的全局等效电路模型,从电路视角刻画系统的全时间尺度响应特性,阐明交直流混联系统的暂态惯量传导和频率/电压自主恢复机制;最后,基于硬件在环实验平台,验证所提控制策略与等效电路模型的有效性.
The hybrid AC/DC/distributed energy storage(DS)microgrid(MG)can enhance energy accessibility and supply stability in remote areas.Whereas conventional MG typically regulate either AC frequency or DC bus voltage independently,the hybrid AC/DC/DS MG feature coupling between frequency and voltage,preventing transient deep drops and large steady-state excursions.To address these challenges,this paper proposes a transient global inertia sharing and steady-state frequency/voltage recovery control strategy to achieve multilateral inertia conduction between subgrids and steady-state frequency/voltage autonomous recovery.Additionally,this paper develops a global equivalent circuit model of hybrid AC/DC/DS MG,characterizing the system's full-time-scale response from a circuit perspective.It elucidates the transient inertia sharing and the autonomous restoration mechanisms of steady-state frequency and voltage in the hybrid AC/DC/DS MG.Finally,the proposed control strategy and equivalent circuit model are validated on a hardware-in-the-loop experimental platform.
