Optimal angle droop power sharing control for autonomous microgrid

In this paper, an improvement in power sharing for Autonomous Microgrid is well established. All previous studies were based on voltage and frequency droop control to share power between distributed generators. This paper develops a new robust voltage and angle droop control to share power, where its advantage over the common frequency droop is in less frequency variation. The synchronization of Power Inverters is integrated within the Angle Droop Control, thus no external signals are needed for synchronization so the system is fully autonomous and possess “plug and play” feature. Modeling and Simulation of a Microgrid system is done to test the effectiveness of the proposed topology. Experimental results are provided to verify the analysis and the design of the Angle Droop Control.
