Abstract

The voltage and VAR issues have become a significant problem in
recent years. This is due to the steadily increasing power system sizes, high
loading of transmission facilities and abnormal operating conditions arising
from inadequate VAR balance. The problem has worsened with voltage
instability that arise in mature systems. The blackout events have confirmed the
importance of reactive power planning and dispatching in maintaining the
security of modern power systems. An algorithm of reactive power dispatch is
described which incorporates the voltage collapse proximity indicator to
minimize the possibility of voltage collapse in the system.
