摘    要:提出了一种电力系统在线静态安全校正算法.该算法基于连续线性规划技术,将安全校正问题分解为非线性潮流和线性控制灵敏度计算子问题以及基于灵敏度的线性规划控制子问题.在线性规划控制子问题中采用了扩大参与约束集策略、主导约束预测策略、筛选参与控制集策略和限制部分控制的有效可控区间策略等来提高在线计算的效率.对3个大型实际系统进行的数值分析表明文中所提算法是十分有效的.

关 键 词:电力系统  静态安全  校正控制  连续线性规划  灵敏度

Abstract:An on-line static security corrective control approach for large-scale power system was presented. The corrective control problem was decomposed into a nonlinear power flow and linear sensitivity computation sub-problem and a sensitivity-based linear programming optimization control sub-problem. Some schemes such as amplifying the involved constraint set, predicting the leading constraints, screening the involved control set and limiting validation regions of partial controls to improve the efficiency of on-line linear optimization model solution were utilized in linear programming control sub-problem. Applying above-mentioned control approach to three actual large-scale power grids, the numerical analysis results show that the presented control approach is very effective.
Keywords:Power system  Static security  Corrective  control  Successive linear programming  Sensitivity
