论文摘要
在亚电递送系统中广泛利用可再生能源（RES）会导致电源质量（例如违反电压）的严重问题，从而大大削减了可再生能源。这是由于可再生能源的固有变异性和子跨性系统的高R/X比。为了充分利用可再生能源，电池储能系统（BESS）通常用于减轻RESS巨大波动的负面影响。电源流路由器（PFR）也可以视为一般类型的网络侧控制器，也已验证以增强可容纳可再生能源的网格灵活性。在本文中，我们调查了PFR在帮助BESS可再生能源住宿方面的价值。用和不带PFR的零可再生功率削减所需的最低BES能力来评估PFR的性能。在多周期优化模型中考虑了BESS的操作约束和PFR的终端电压特性。通过在修改的IEEE 30总线接触系统上的数值模拟测试了所提出的模型，而显着的结果表明，可以通过在单个线上安装PFR来实现15％的BES能力。
Widespread utilization of renewable energy sources (RESs) in subtransmission systems causes serious problems on power quality, such as voltage violations, leading to significant curtailment of renewables. This is due to the inherent variability of renewables and the high R/X ratio of the subtransmission system. To achieve full utilization of renewables, battery energy storage systems (BESSs) are commonly used to mitigate the negative effects of massive fluctuations of RESs. Power flow router (PFR), which can be regarded as a general type of network-side controller, has also been verified to enhance the grid flexibility for accommodating renewables. In this paper, we investigate the value of PFR in helping BESSs for renewable power accommodation. The performance of PFR is evaluated with the minimum BESS capacity required for zero renewable power curtailment with and without PFRs. The operational constraints of BESSs and the terminal voltage property of PFRs are considered in a multi-period optimization model. The proposed model is tested through numerical simulations on a modified IEEE 30-bus subtransmission system and a remarkable result shows that 15% reduction of BESS capacity can be achieved by installing PFRs on a single line.
