摘要

介绍了内点法(IP)在电力系统电压稳定预防纠偏控制(PCC)中的应用。提出了基于控制成本的预防/纠正控制的数学模型。在实时模式下，当工作点与稳定边界之间的电压稳定裕度过小时，进行预防性控制。在研究模式中，当电压不安全时进行校正控制。预防/纠正控制后，电力系统的工作点不仅应在电压安全区内，而且应保持一定的电压稳定裕度。该方法已在从100总线系统到4000总线系统的5个系统上成功地进行了测试。

Preventive/corrective control for voltage stability using direct interior point method

This paper describes the applications of the interior point (IP) method on preventive/corrective control (PCC) for power system voltage stability. The mathematical model of preventive/corrective control, based on the control costs, is proposed. In the real-time mode, preventive control is carried out when the voltage stability margins between the operating point and the stability boundary are too small. In the study mode, corrective control is carried out when the voltage is insecure. After preventive/corrective control, not only should the power system operation point be in the voltage secure area, but some voltage stability margins should also be maintained. The approach proposed has been successfully tested on five systems-from 100 bus system to 4000 bus system.
