摘要
提出一种基于约束转换方法的建立暂态稳定约束最优潮流(OTS)的算法.运用函数转换技术等价变换OTS为半无限优化(SIP)问题,转换后的SIP问题与常规的最优潮流(OPF)具有相同的维数;基于有效集策略设计了转换后SIP问题的迭代法,该方法减少了子问题中不等式约束的个数.电力系统的2个数值仿真例子验证了所提出算法的有效性.
Optimal power flow with transient stability constraints (OTS) becomes an effective tool for power system operation since it considers economy and dynamic stability simultaneously. Therefore, a method to be stablish OTS based on constraints conversion is proposed. By using the functional transformation technology, OTS is converted into a semi-infinite programming (SIP), which has the same dimension as common optimal power flow (OPF). Based on the active strategy, an iterative method is presented for the reformulated SIP problem, in which the number of inequality constraints in the subproblem is reduced. TWO practical OTS examples show the effectiveness of the proposed method.
