Assessment of energy storage effect into automatic reclosing in Smart Grid

This paper deals with two transient states of the Russky Island power network, that can be recognized as a middle size Smart Grid, and which located at the end portion of the Russian South-East. In some cases, two transmission lines between the island and mainland grids can be emergency disconnected, and then a transmission line auto-reclosing might take place. The object of the paper is examination of possibility of using an energy storage unit in this Microgrid in order to improve condition for auto-reclosing. In addition, effectiveness of improving the Under Frequency Load Shedding implementation with the use of the energy storage emergency control, when the transmission line auto-reclosing has to be forbidden, is examined. These studies have been fulfilled with the use of the well-known MATLAB/Simulink software. The investigation results could be useful for forthcoming porting of this power network into the electricity grid of Vladivostok.
