Universal Protection Software and its Application in Smart Grid

Abstract

Nowadays electrical power systems are growing up and distribution networks are increasingly complicated due to high penetration of renewable energy resources. Smart grid includes several micro grids and utility system. It provides bidirectional feature of power and information among generations and consumers. In addition, consecutive switching of energy resources and microgrid operation modes causes variety of network configurations. Hence, it requires a real time adaptation of protective systems. In this paper, Universal protection software based on protection requirements is proposed to design protective system. The software is applicable in offline and online mode. The online feature updates protective configuration and setting parameters based on changing network configuration by means of a hardware interface.
