Special Issue Information

Dear Colleagues,

The very fast increase in the world’s energy demand over the last decade, and the request for sustainable development, can be approached using microgrids based on hybrid power systems combining renewable energy sources and fuel cell systems.

Thus, to highlight the latest solutions in the implementation of fuel cell renewable hybrid power systems, this Special Issue, entitled “Fuel Cell Renewable Hybrid Power Systems 2021”, has been proposed for the international journal Energies. The present Special Issue of Energies aims to collect innovative solutions and experimental research, as well as state-of-the-art studies, in the following topics:

  • Fuel cell (FC) systems: modeling, control, optimization, and innovative technologies to improve the fuel economy, lifetime, reliability, and safety in operation;
  • Hybrid power systems (HPSs) based on renewable energy sources (RESs) (RES HPS): optimized RES HPSs architectures; global maximum power point tracking (GMPPT) control algorithms to improve energy harvesting from RESs; advanced energy management strategies (EMSs) to optimally ensure the power flow balance on DC (and/or AC bus) for stand-alone RES HPSs or grid-connected RES HPSs (micro-grids);
  • RES HPS with an FC system as a backup energy source (FC RES HPS): innovative solutions to mitigate the RES power variability and load dynamics to energy storage systems (ESSs) by controlling the generated FC power, DC voltage regulation, and/or load pulse mitigation by active control of the power converters from hybrid ESS;
  • FC vehicles (FCVs), electric vehicles (EVs) and hybrid electric vehicles (HEVs): FCV/EV/HEV powertrain, ESSs topologies and hybridization technologies, and EMSs to improve the fuel economy and ESS lifetime;
  • Advanced technologies in microgrids: vehicle-to-everything (V2X), blockchain, smart contracts, cyber-security, etc.;
  • Optimal sizing of FC RES HPSs, FCVs, ESS, and microgrids;
  • Hydrogen production and its specific use in energy applications.

The papers received are subject to a rigorous, but fast, peer review procedure, ensuring the wide dissemination of research results accepted for this Special Issue. I am writing to invite you to submit your original work to this Special Issue. I look forward to receiving your outstanding research outcomes.

Title: Adaptive Hamiltonian Control Law for Constant Power Load Stability Issue in DC Microgrid: Case Study for Multiphase Interleaved Fuel Cell Boost Converter

Abstract: The cascaded connection of converters in a DC microgrid may cause instabilities because converters performing as loads exhibit constant power load (CPL) characteristics. In this study, the construction of the feedback controller of a multiphase interleaved fuel cell (FC) boost converter is based on the adaptive Hamiltonian control law, including two integral terms to guarantee that there is no steady-state error in the important DC bus voltage and current balancing of each input inductor current. It is certified through the design that the desired equilibrium point is (locally) asymptotically stable by using the Lyapunov stability proof. The control approach is authenticated via digital simulations and experimental prototyping, with a 2,500 W FC converter supplied by an FC/reformer size of 2,500 W and 50 V.
