基于Filter集合的内点算法(FIPM),提出了一种最优潮流新算法(FIPOPF),该算法可针对最优潮流问题的实际情况对可行方向进行自适应校正,即在不可行情况下通过求解仅含“硬约束”的优化问题进行可行方向调整,从而可使系统在无可行解时收敛至一个对系统“软约束”违反最小的稳定点。对五个IEEE标准算例和两个实际系统的分析和试算均表明,所提出的算法具有很好的收敛性,运算速度较快,满足在线最优潮流计算的时间要求。
A new OPF algorithm (FIPOPF) is proposed based on Filter Interior Point Method (FIPM), which can correct the iteration direction adaptively in face with the practical OPF problem. If there is no feasible solution, FIPOPF will converge to a stable point which will minimize the possibility of violation of "soft constraints" by solving an optimal problem which has only "hard constraints". Numerical tests in five IEEE test systems and two actual systems show the robustness and high efficiency of the proposed method, which could satisfy the requirement of online optimal dispatch of the power system.
