【摘要】 从静态安全域的角度出发,以正常状态下和"N-1"故障下静态安全域的定义与运行点至边界面距离的求解方法为基础,给出交直流协调校正控制和预防控制的控制目标选择和控制策略制定的准则,并根据不同的实际场景需求和控制目标建立交直流协调控制优化模型。最后的算例表明该方法在交直流协调控制和调节柔性负荷上具有可行性,使电力系统安全控制更具有几何直观性和自主性。更多还原

【Abstract】 From the perspective of static security domain,this paper presents criteria of control objective selection and control strategy formulation for AC/AD coordinated correction control and prevention control on the basis of definitions of static security domain and solving methods for the distance from operating point to the boundary surface in normal state and under"N-1"fault condition.According to different actual field requirements and control objectives,it also builds optimization models for AC/DC coordinated control.Actual examples indicate this method is feasible in AC/DC coordinated control and flexible load regulation,which may make security control for the power system with geometrical visualization and autonomy.更多还原
