Integration of Hybrid Energy sources for Grid Connected AC Distribution System

This paper proposes renewable energy system interface with AC distribution system. AC interface allows for increases the system efficiency and decreases the power demand. In this project issues on renewable system interfaces with AC system are analyzed theoretically. In addition, this project proposes a protective scheme for islanding detection. In current scenario islanding condition is dangerous for grid workers who may not know that load is still powered even though there is no power from the grid. For this reason islanding condition must be detect and immediately stop producing power. For that aspects, this project proposed a new current injection control technique using microcontroller to detect the islanding condition and provide the human safety and equipment protection.
