摘要
研究了一种新的提高系统电压稳定性的方法——二次电压控制。利用二次电压控制结构化模型推导了选择主导节点的优化目标 ,讨论了遗传算法在主导节点选择中的应用。建立了二次电压控制系统相应的二次性能指标 ,确定了具体的二次电压控制策略。
This paper studies a new approach, secondary voltage control, to improve voltage stability. In this work. Theobjective of optimization in pilot bus selection is derived based on the structural model of secondary voltage control and theapplication of genetic algorithm to pilot bus selection is discussed. The control objective that has important effect on voltagestability is determined and the relevant control strategy is proposed. Lastly. the conclusion that secondary voltage control caneffectively enhance the voltage stability is verified by simulation results.
