Abstract

In this chapter, the author presents the operation and power management of the hydrogen storage-based smart DC microgrid (DCMG). In this microgrid, several renewable distributed generations (DGs) such as wind turbine, solar photovoltaic system, solid oxide fuel cell (SOFC), and battery energy storage system are interconnected together and to the various DC and AC loads to form a ring-type low voltage distribution network. An additional storage as Hydrogen storage system has been connected to the dc microgrid for balancing the power at all times in the DCMG, under islanded mode operation, for all practical cases. An architecture of the hydrogen storage-based DC microgrid is suggested mainly for the remote rural area. For the regeneration of the electricity from the stored hydrogen, a SOFC DG system is also used in the proposed DCMG. A control technique is also developed for the operation of the hydrogen storage-based DCMG. The proposed DCMG system provides a reliable and high-quality power supply and will supply the power to all loads (both DC and AC) simultaneously.
基于储氢的智能直流微电网的运行
在本章中,作者介绍了基于储氢的智能直流微电网(DCMG)的运行和电源管理。在该微电网中,风力发电机组、太阳能光伏发电系统、固体氧化物燃料电池(SOFC)、蓄电池储能系统等多台可再生分布式发电机组(dg)相互连接,并与各种直流和交流负荷相互连接,形成环形低压配电网。一个额外的储氢系统已连接到直流微电网,在孤岛模式下,在所有实际情况下,在DCMG中随时平衡功率。提出了一种主要面向偏远农村地区的储氢直流微电网结构。为了从储存的氢气中再生电力,SOFC DG系统也被用于提议的DCMG。研究了储氢DCMG的运行控制技术。所提出的DCMG系统提供了可靠的高质量电源,并将同时为所有负载(直流和交流)供电。
