Hierarchical voltage control strategy in interconnected power systems

In interconnected power systems, voltage variation is controlled in a centralized way which can only be done at the control centre to monitor and restore the voltage profile in the system within the permissible value. A large power system can have a complicated network which makes coordination a dif...
