Adaptive Dynamic Grid Partitioning for Reactive-Power/Voltage Control Based on Secondary Voltage Control

Reactive power voltage partition control is an important part of AVC secondary voltage control. Aiming at the current status of secondary voltage control, based on the voltage/reactive sensitivity and modularity function, an adaptive dynamic partitioning method is proposed, which changes with the operating conditions of the grid. With each reactive power source partition center, the load nodes are mapped to the corresponding reactive power sources according to the voltage/reactive sensitivity, and the regional merging automatically forms the optimal partition by using the modularity function as a measure. Finally, the proposed method is verified by the IEEE-39 system.
