Voltage Stability Analysis for Shanghai Metropolitan Grid with High-Level Power Import and Scale-Reduced Online Units
In view of the operation features of Shanghai Metropolitan Grid (high-level power import and scale-reduced online units),this paper comprehensively evaluates voltage stability performance with various levels of online units,in the modes of grid normal operation,maintenance and contingencies.The minimum level of online units to meet the voltage stability criterion is investigated so as to provide technical support for the secure and stable operation of Shanghai Metropolitan.Grid.
