摘　　要：暂态稳定预防控制是电力系统预防严重故障的有效措施之一。首先,利用双向堆叠简单循环单元(Bi-S-SRU)对电力系统运行时间序列整体感知能力强的特点,建立输入特征与暂态稳定指标之间蕴藏的映射关系,将建立的映射关系替代暂态稳定约束最优潮流(TSCOPF)模型中的非线性微分代数方程以简化计算;然后,结合自适应粒子群(APSO)优化算法,在保证系统稳定性的前提下,考虑发电调度成本最小化,形成预防控制策略;最后,在IEEE 39节点系统上进行测试,验证了所提方法的可行性。Transient stability preventive control is one of the effective measures to prevent serious emergencies in power systems.Firstly,the mapping relationship between input characteristics and transient stability index is established based on bi-directional stacked simple recurrent unit(Bi-S-SRU),which is characterized by its strong perception of the power system running time series.The nonlinear differential algebraic equation in transient stability constrained optimal power flow(TSCOPF)model is replaced by this mapping relationship to simplify the calculation.Then,combined with the APSO optimization algorithm,the preventive control strategy is formed considering the generation scheduling cost minimization under the premise of ensuring the stability of the system.Case study on IEEE 39-bus system demonstrates the feasibility of the proposed method.
