In power system reconfiguration after successful black start, the maximum restorable load that substation can pick up at one time should be given. Presently, researches about the problem usually concentrate on frequency constraint and steady-state voltage constraint. In this paper, a method that can give the maximum restorable load is proposed which considers transient voltage-dip acceptability (TVDA)...
Voltage stability of Shandong power system is analyzed by power transmission path analysis. Weak buses are decided by local voltage stability index. Voltage stability indices of both active power transmission paths from the west to the east and local reactive power transmission paths are computed with load increasing. The reactive power reserve indicator is also calculated and key factors that have...
The hierarchical voltage control has been proved to be an effective method to ensure the security, stability and economy operation in power systems. The secondary voltage control is represented by the multiple objective linear programming with sensitive analysis in this paper. Several control objectives are considered. The first objective is that the pilot node voltage should be close enough to the...
