This paper proposes the two-stage optimization of superconducting magnetic energy storage (SMES) integrated into hybrid wind/photovoltaic (PV) generators considering the state of charge (SOC) control for stabilizing voltage and power fluctuations. The first stage aims to achieve the minimal coil inductance of SMES that guarantees the stored energy for system stabilization. In the second stage, the control parameters of SMES are optimized to keep the SOC at the desired level. As a result, the minimum coil inductance with sufficient stored energy of SMES for stabilizing system and regulating SOC at the target value can be obtained for entire period of operation. Study results in the distribution system with various loads ensure that the hybrid wind/PV with optimized internal SMES yields superior stabilizing performance in comparison with the SMES externally installed at the wind/PV terminal.

基于 SOC 控制的两级优化安装在风光互补系统中的 SMES 以稳定电压和功率波动



本文提出了将超导磁储能(SMES)集成到混合风/光伏(PV)发电机中的两阶段优化,考虑到稳定电压和功率波动的充电状态(SOC)控制。第一阶段的目标是实现 SMES 的最小线圈电感,以保证系统稳定的存储能量。在第二阶段,优化 SMES 的控制参数以将 SOC 保持在所需水平。因此,在整个运行期间可以获得具有足够SMES存储能量的最小线圈电感,以稳定系统并将SOC调节在目标值。具有各种负载的配电系统的研究结果确保,与风电/光伏终端外部安装的 SMES 相比,具有优化的内部 SMES 的混合风电/光伏具有更优异的稳定性能。
