By analyzing the contribution factor,a study on the oxygen consumption rate of chlorobenzene homologue under the condition of cosubstrate was conducted.

The influence of adjusting active output of units during dynamic congestion management on system transient stability is analyzed; the contribution factor of unit to transient stability index is calculated and according to the calculated factor the dynamic congestion cost is allocated.

By applying the newly developed nonlinear function contribution factor theory and practical power system steady stability analysis method,the allocation of single machine infinite system and multimachine steady stability margin is studied,the contribution of generator node MVA power to steady stability margin is obtained.
