Increasing efficiency and decreasing cost are the main purposes in the design of the power generation systems. In this study two hybrid systems: solid oxide fuel cell (SOFC)-gas turbine (GT) and SOFC-GT-steam turbine (ST); are considered. Increasing the SOFC input temperature causes thermodynamics improvement in the hybrid system operation. For this purpose, using two set of SOFC reactants heat...

−Hybrid electric vehicles (HEV) utilize electric power and a mechanical engine for propulsion; therefore, the performance of HEVs is directly influenced by the characteristics of the energy storage system (ESS). The ESS for an\ HEV generally requires high power performance, long cycle life, reliability and cost effectiveness; thus, a hybrid energy storage system (HESS) that combines different t...

This study deals with system integration and power management of a stand-alone renewable energy (RE) hybrid system, which is in its final stage of construction in Lambton College (Sarnia, Ontario, Canada). The system consists of five main components: photovoltaic (PV), wind turbine, electrolyzer, hydrogen storage tanks and fuel cell. The model for each process component was developed and the hy...

This paper presents a novel multi-port DC/DC converter which is suitable to be used as the interface of hybrid renewable energy systems. The converter contains three unidirectional power flow ports which two of them are input ports and are connected to two independent energy sources while the third one is the output port that feeds a standalone load. Furthermore, the proposed converter contains...

exergy analysis of an integrated molten carbonate fuel cell-turbo expander-steam turbine hybrid cycle has been presented in this study. the proposed cycle has been used as a sustainable energy approach to provide a micro hybrid power plant with high exergy efficiency. to generate electricity by the mentioned system, an externally reformed molten carbonate fuel cell located upstream of the combi...

Three Port Converters are used for merging more than a single source in order to improve the power handling capability. Here the first two ports acts as the sources and the third port acts as the output or to the Load. The objective is combining the Wind Energy Systems with the Existing Three Port Converter System instead of a Battery Storage. The proposed system is simulated and verified using...

Renewable energy technologies are suitable for off-grid services, serving the remote areas without having to build or extend expensive and complicated grid infrastructure. Therefore standalone system using renewable energy sources have become a preferred option. This paper is a review of hybrid renewable energy power generation systems focusing on energy sustainability. It highlights the resear...
