求翻译：(b)方向2则优先减少对系统暂态稳定性能影响较大的机组出力，甚至关停原本属于易失稳机群的发电机，同时减少的发电功率均匀分布在该区多个节点，有利于全区共同分担不平衡功率，不易造成局部运行条件严重恶化，因此得到的ATC值较方向1大。是什么意思？

(B) direction of the two priorities to reduce the performance impact on system transient stability contribute to the larger unit, or even shut down the original fleet of generators are easy to instability, while reducing the power output more uniform distribution of nodes in the area, help imbalance

(b) in the direction of system 2 priority reduction transient stability can contribute to a greater impact, and even shut down the unit originally belonging to vulnerable groups of aircraft who lost the generator and at the same time reducing the power generating power evenly distributed in the regi

(B) 2 you give priority to reducing the impact on transient stability of system output of larger units, or even shut down originally belonging to the instability of generators of the cluster, while reducing power evenly distributed in the area of multiple nodes, to share the unbalanced power through
