Abstract In microgrids, hybrid energy storage system (HESS), which consists of batteries and supercapacitors (SC), is used to maintain the power balance between the intermittent renewable energy source (RES) and the changing load demands. A sudden large change in the RES generation or the load demand might result in long rise/fall-time and large over/undershoot, causing high dynamic error in output voltage. In this paper, the current reference of HESS generated by PI controllers is translated to a positive falling signal, which can be compensated by an adaptive compensation related to the dynamic voltage error. The proposed control strategy significantly reduces the rise and settling-times, making a faster response, with reduced voltage fluctuation. Simulation results substantiate the effectiveness of the proposed method, which are further validated using a realistic hardware test setup.

基于上升沿和下降沿补偿的光伏微电网混合储能系统快速控制策略

摘要 在微电网中，由电池和超级电容器（SC）组成的混合储能系统（HESS）用于维持间歇性可再生能源（RES）和不断变化的负载需求之间的功率平衡。RES 生成或负载需求的突然大变化可能会导致上升/下降时间过长和过大/下冲，从而导致输出电压的高动态误差。在本文中，由 PI 控制器生成的 HESS 的电流参考被转换为正下降信号，该信号可以通过与动态电压误差相关的自适应补偿进行补偿。所提出的控制策略显着减少了上升和稳定时间，从而实现了更快的响应，并减少了电压波动。仿真结果证实了所提出方法的有效性，
