摘要

本研究采用基于频率解耦的功率分路来管理基于直流微电网(DC-MG)的光伏和混合储能系统(HESS)，该系统由电池和超级电容器组成。HESS控制集成了母线电压调节和恢复以及HESS充放电控制的双环结构。迟滞电流控制(HCC)采用低通滤波(LPF)控制来跟踪超级电容器的设定值电流。采用标准和先进的LPF方法对脉冲、平滑和扰动PV和负载波形进行了系统可靠性评估。Matlab仿真结果证实了该系统在不同资源波形下的良好控制性能。采用关键性能指标(kpi)对母线电压、HESS电流管理进行评价

Robust Frequency-Decoupling-Based Power Split of Battery/Supercapacitor Hybrid Energy Storage Systems in DC Microgrids

: A frequency-decoupling-based power split was used in this study to manage a direct-current microgrid (DC-MG)-based PV and hybridized energy storage system (HESS), which consisted of a battery and a supercapacitor. The HESS control integrated a dual-loop structure for bus voltage regulation and recovery and HESS charge/discharge control. Hysteresis current control (HCC) tracked the supercapacitor setpoint current using low-pass ﬁltering (LPF) control. The system reliability was assessed using pulsing, smooth, and disturbed PV and load waveforms with standard and advanced LPF methods. The Matlab simulation results conﬁrmed a superior HESS control performance under varying resource waveforms. Key performance indexes (KPIs) were used to evaluate the bus voltage, HESS current management
