Energy Management Supervisory Controller Embedded-Board for Islanded Hybrid AC/DC Microgrids

Abstract

Microgrid systems have received much attention as they can make a way for more efficient power flows in the modern power systems. This paper presents a hybrid AC/DC microgrid to reduce the processes of multiple conversions in an individual AC or DC microgrid. In this paper, a new method of the supervisory controller is proposed to autonomously control and monitor for an islanded microgrid and to maintaining more stable energy flows with maximum utilization of renewable resources. The supervisory controller enables the microgrid system to operate in different modes of operation by the coordination control algorithms in the different components for smooth transfer of power between AC and DC networks. With the energy management option of the supervisory controller, this supervisor also provides an efficient load scheduling method to meet varying power supply needs and manage the sources and allow the microgrid to make a good operation and decisions. Therefore, in this paper, an islanded AC/DC microgrid has been modeled and simulated to identify the relevant technical issues involved in the operation of a microgrid system based on renewable power generation units using MATLAB/Simulink, and a new method of an energy management system is proposed for monitoring the islanded microgrid.
