for example, since different operating points of power system have different stability characteristics, utility engineers often perform a large number of stability studies to search for a stable one by trial-and-error methods incorporating engineering experience 目前各电网调度中心主要采用的试错搜索法结合稳定计算经验来寻找保持暂态稳定的运行方式的方法,现在看来无疑是耗时的和不完善的。
