Abstract

This paper proposes renewable energy system interface with AC distribution system. AC grid interaction improves the efficiency of the system and reduces the power demand. In this paper, issues on renewable system interfaces with AC system are analyzed theoretically. In addition, this paper proposes a protective scheme for islanding detection. In current scenario islanding condition is dangerous for grid operators who were not aware of the power from the distributed generation supplying load still connected even though there is no power from the grid. For this reason, islanding condition must be detected and immediately stopped from producing power. For that aspects, this work proposed a new current injection control technique using microcontroller to detect the islanding condition and provide human safety and equipment protection
