  Centralized secondary voltage control in a power system has been replaced by
the distributed controller in the recent literature due to its high dependency
on extensive communication messages. Although in the new method each
distributed generator only communicate with its neighbors to control the
voltage, yet the messages are circulating among the whole system. In this
paper, we have utilized distributed controller locally so that it will work as
a fully distributed control system. This controller has been justified by being
studied within a case study including 6 distributed generators.
