Integrating URFC in Islanded Green Hydrogen-Based Microgrid Including Onsite Renewable Generation

Integrating unitized reversible fuel cells (URFCs) in microgrid (MG) frameworks offer a unique opportunity for bidirectional services. While URFC's hold significant potential, coordinating its operation within MGs remains challenging. To address this challenge, this paper proposes a thorough investigation and coordination scheme of detailed dynamic URFCs in a green hydrogen based islanded MGs. The proposed scheme enables the URFC to participate in supporting the DC link voltage, thereby redefining the role of the dispatchable source in the MG. It also coordinates multiple URFCs in a MG enabling them to switch modes according to the operating conditions. Several case studies have been conducted using simulation and real time analysis platforms that integrate URFC into an islanded MG, highlighting the operational advantages that the proposed scheme offers.
