Coordinated Optimization and Control Technology between Active and Reactive Power

Abstract:

As the coupling between active and reactive power is enhanced along with the expansion of the grid scale and the AC-DC hybrid operation, voltage stability is not only closely related to reactive power, but also related to active power. By the constraints of generator power circle and its operating limits, the mechanism of interaction between the active and reactive power is clarified. Also, the hierarchy structure of coordinated optimization and control technology between them is established, and an improved AGC control strategy consideration to static voltage stability is proposed. By optimizing the active power output of the AGC unit, the dynamic reactive power reserve capacity of each unit is improved and the system voltage is supported. The strategy is verified through a variety of experiments on the IEEE-39 bus system.
