This paper investigates the control mechanism for intentional islanding transition, when a Low Voltage (LV) or Medium Voltage (MV) distribution system, which is usually under grid connection mode, is supposed to be separated from the upstream grid, due to either maintenance or a disturbance in the grid. The concept of Islanding Security Region (ISR) has been proposed as an organic composition of the developed control mechanism. The purpose of this control mechanism is to maintain the frequency stability and eventually the security of power supply to the customers, by utilizing resources from generation and demand sides. The control mechanism can be extended to consider the distributed generations like wind power and other innovative technologies such as the Demand as Frequency controlled Reserve (DFR) technique in the future.
