Simulation Study of Power Management for a Highly Reliable Distribution System using a Triple Active Bridge Converter in a DC Microgrid

Abstract

Owing to the acute energy shortage issue and the increasing energy demands of information and communication technology systems worldwide, the development of a DC microgrid that can utilize renewable energy sources, such as wind and photovoltaic power, has been accelerated. Therefore, power management for DC microgrid distributed systems is promoted to achieve high reliability and efficiency in power distribution systems. For industry and power transmission applications such as data centers, power management with the help of DC converters is highly recommended. In this paper, we propose a prototype of a power distribution system with a triple active bridge (TAB) converter for data centers in the DC microgrid. Moreover, we introduce a power management approach for a distribution system using the TAB converter. Finally, we perform simulations of the proposed configuration to verify the controllability of the circuit performance and the high reliability of the system.

Applications of Triple Active Bridge Converter for Future Grid and Integrated Energy Systems

“…Balancing the load can improve the sustainability of the system. In order to improve the reliability of the data center distribution system, the TAB converter was proposed to share the power between the distribution lines in [52], as shown in Figure 17. The power distribution in each load group is evaluated.…”

Proposed energy management for a decentralized DC-microgrid based PV-WT-HESS for an isolated community

“…In the last years, there is a quick increase of clean and sustainable energy-based renewable energy sources REs in power systems [1]. To make the best utilization of renewable energy, Microgrids have been widely studied and have an important role in the future energy [2], to decrease the consummation of fossil energy and to create a solution for remote areas. A Microgrid system integrates several types of REs to feed the household and industrial load.…”

“…DC-MG combines various REs such as photovoltaic PV, wind turbine WT, Fuel cell FC and biomass, in addition to storage devices such as chemical batteries, electrical supercapacitor SC and flywheel, and DC loads [3]. DC-MG systems present more advantages compared to traditional AC-MG, where we neglect alternative parameters and disturbances [2]. In literature, DC-MG is more advantageous compared with AC-MG in term of the initial cost, the net saving value, the payback period and the system efficiency [4].…”
