Static Hybrid Automatic Voltage Control Systems

The concept of hybrid power control system is introduced to the power systems´ voltage control, and the static hybrid automatic voltage control (HAVC) system has been established in the paper. Firstly, we set up a new hybrid hierarchical voltage control system model based on the hybrid theory, and design the operating process. Then we define the stability event and the economic event to drive the system, through which we achieve the synthetic objects of safety, stability and economy. Moreover, the system provides a much easier access to achieve optimal automatic voltage control, thus highly feasible in practice. The system´s controlled targets, which are driven and decoupled by discrete events, are dispatched to different modules of sub-layer, so that the calculations become more efficient with better use of available technologies. Computer simulation results have proven the validity of the system and the approaches designed in the paper.
