The System Design and Demonstration for Autonomous Microgrid Operation

Abstract

-The autonomous microgrid is a system that is autonomously operated depending on the grid and internal load condition, without the operator's intervention. In this study, a control algorithm for the microsource and an operation algorithm for the microgrid are proposed to realize the autonomous microgrid system. In addition, a microgrid operation system based on the operation algorithm is proposed. The electromagnetic transient program is used by the proposed microsource control algorithm for simulation, and the validity of the algorithm is verified. The proposed operation system is verified based on a case study using a simulator and test devices.

“…The Autonomous Microgrid is a system that is autonomously operated depending on the grid and internal load condition, without operator's intervention [31]. The motivation of AMG is that in face of rapid increase in intermittent renewable energy sources fed in distribution network, regulation of distribution network becomes so complicated that manual operation is soon unable to satisfy all the regulation requirements.…”
