Grid Islanding for Secure Operation of Power System

Abstract

In order to increase the reliability of the power system intentional islanding strategy has been considered by
utilities. Millions of customers are affected each year due to blackouts. Splitting a transmission system into smaller
islands could significantly reduce the effect of these blackouts. This paper proposes an intentional islanding method to
enhance the voltage stability. In islanding operation relying on the hydraulic turbine governor (HTG) which specifically
performs the speed and active power control of the islanded generators is the main achievement. This paper shows the
behavior of a distribution network consisting of hydro generators.
