“…This way, the power demand could be adjusted to meet the excess power generation of the wind turbine to improve the efficiency and controllability of the microgrid. Another possible aspect that could be optimized is the operation of the fuel cells, which could be similar to the one carried out in [8]. This optimization is based on operating one of the fuel cells at its maximum efficiency point (0.33kW of output power), while the other one is in charge of balancing the microgrid.…”

Nowadays, there are residential buildings which cannot be connected to a distribution network, due to the lack of electric infrastructure. Also, there are other electric applications where it is necessary to have a backup system, i.e. hospitals, hotels, etc. Additionally, there are users who just want to be off-grid. In all these cases, a dedicated stand-alone generation system can provide a valuable service. In this context, this paper is focused on testing and analysis of a real small stand-alone generation system composed by two proton membrane exchange fuel cells (PEMFC) and a micro wind generator (WG). The key feature of this configuration is to be an on-site zero-emission system. Additionally, quality of supply and energy efficiency of this microgrid in islanded mode are analyzed. Furthermore, possible optimization methods and future enlargements of the system are proposed, in order to improve the overall efficiency of the proposed microgrid.

“…Another strategy focused on energy efficiency optimization was presented by authors of [92], where their aim was to build a control system capable of optimizing the FC-based microgrid power delivery and subsequently the efficiency. A microgrid made of two PEMFCs was used to develop and test the effectiveness of the proposed control strategy, the energy performance and to ensure that the integration is optimized [92]. Two boost converters are also employed to boost the FC output voltage and keep it stable.…”

“…Before the control strategy was defined, experimental tests were carried out to pinpoint the optimal efficiency of the FCs regarding the generated power and working temperature [92]. Upon realizing the values of these two figures or conditions, a control strategy aiming at producing maximum efficiency of the microgrid was defined with three cases of power demand to be used in order to achieve the desired results.…”

“…The intelligent energy management system (IEMS) is a control system which monitors the voltage, current, and output of each device and the system state in real time and enables the system to be operated reliably. It adjusts the load of the load bank according to the load pattern in real time and allows the different devices to be synchronized [42][43][44][45][46].…”

The need for technological development to reduce the impact of air pollution caused by ships has been strongly emphasized by many authorities, including the International Maritime Organization (IMO). This has encouraged research to develop an electric propulsion system using hydrogen fuel with the aim of reducing emissions from ships. This paper describes the test bed we constructed to compare our electric propulsion system with existing power sources. Our system uses hybrid power and a diesel engine generator with a combined capacity of 180 kW. To utilize scale-down methodology, the linear interpolation method is applied. The proposed hybrid power source consists of a molten carbonate fuel cell (MCFC), a battery, and a diesel generator, the capacities of which are 100 kW, 30 Kw, and 50 kW, respectively. The experiments we conducted on the test bed were based on the outcome of an analysis of the electrical power consumed in each operating mode considering different types of merchant ships employed in practice. The output, fuel consumption, and CO2 emission reduction rates of the hybrid and conventional power sources were compared based on the load scenarios created for each type of ship. The CO2 emissions of the hybrid system was compared with the case of the diesel generator alone operation for each load scenario, with an average of 70%~74%. This analysis confirmed the effectiveness of using a ship with a fuel-cell-based hybrid power source.
