Real-Time Control and Operation for a Flexible Microgrid with Dynamic Boundary

Abstract

To better utilize the existing electric power grid distribution network automation of smart switches, a microgrid can expand or shrink its electrical boundary according to available renewable generation. Previous literature only focused on the design of a microgrid with a dynamic boundary, but without considering real-time operation. This paper proposes a microgrid controller that enables operation of microgrid with dynamic boundary and can be integrated into the existing distribution automation system. The architecture of the control system is introduced, and the essential functions such as online topology assessment and synchronization are presented. Simulation results are given to demonstrate the feasibility of the proposed controller.
