我们为并网光伏（PV）/混合储能系统（HESS）提供了一种新颖的延迟补偿稳定反馈控制。 HESS由电池和超级电容器（SC）组成，具有高能量和功率密度。所提出的控制基于双线性系统的延迟补偿链预测器，具有实时实现可行性和对所需参考轨迹的全局渐近稳定性。并网 PV/HESS 的实时仿真结果验证了我们的方法在存在数字实施延迟的情况下控制其动态的有效性，同时确保向电网输送所需的电力。
We provide a novel delay-compensating stabilizing feedback control for a grid-connected photovoltaic (PV)/hybrid energy storage system (HESS). The HESS is comprised of a battery and a supercapacitor (SC) and features high energy and power density. The proposed control is based on delay-compensating chain predictors for bilinear systems, and it features real-time implementation feasibility and global asymptotic stability to desired reference trajectories. Real-time simulation results of a grid-connected PV/HESS verify the efficacy of our method in controlling its dynamics in the presence of digital implementation delays while ensuring delivery of desired power to the grid.
