System operation constraints are added into the optimization model of GENCOs’ active power output.

Using the power model to determine the operating limits of UPFC, Which include: transmission line voltage magnitude and phase inserted by the series converter, the current going through the series converter, the current inserted by the shunts converter, the active power exchanging between the series and shunts converter, the line-side voltage of the series and the bus voltage of the shunts.

Based on the background of institutional transformation of China,this paper suggests that the household register system and the supporting policies endemic to China constructed the system restraints on the labor interregional mobility.

And this can expand two approaches to constructing public administrative ethics; system restraint and virtue inspiration.
