“…has a unique maximum efficiency point (MEP) and other local peaks on the plateau around the MEP position, and all peaks varies with operating conditions , , . The Fuel_LF‐RTO strategy proposed herein can accurately locate the MEP, but also local peaks if this is imposed and the starting point is set appropriately in the searching range .…”

“…Regarding the DC voltage regulation, this can be performed as correction of the reference current on the control side of the PEMFC system, the battery, or the power storage device (UC). The DC voltage regulation was studied at both FC control and UC control sides in different papers . The DC voltage regulation was implemented here on the control side of the UC stack because the optimization loop was implemented on the control side of the PEMFC stack and the battery is connected directly to DC bus.…”

The Fuel_LF‐RTO strategy is real‐time optimization (RTO) strategy proposed here to find the optimal values of fueling for the polymer electrolyte membrane fuel cell hybrid power sources under unknown load profile, which is the case of fuel cell vehicle. The proposed optimization strategy is based on global extremum seeking (GES) algorithm and load‐following (LF) control for air and fuel flows. The results show the performance obtained with Fuel_LF‐RTO strategy in comparison with the Static Feed‐Forward strategy. The performance was estimated for constant and variable load. The FC system efficiency and the fuel consumption efficiency for maximum load of 8 kW can increase with up to 1.88% and 11.26 W lpm−1 in comparison with the sFF RTO strategy. Also, the fuel economy is 27.36 L during the 8 kW/12 s constant load cycle, which means an economy of 136.8 lpm. This performance is highlighted for constant load in range 2 to 8 kW, which represents 0.33% and 1.25% from nominal power of the 6 kW FC stack used in this study. Also, the performance was estimate for variable load considering the fuel economy, which can be up to 21.86 l during the 6.25 kW/12 s pulsed load cycle.

“…However, the stochastic fluctuation of PV power penetrates into the microgrid, owing to dissimilarities ranges of solar irradiation and temperature. The cascade multilevel inverter has a major contribution to penetrate the distributed generation power into microgrid [4], [5]. The transformerless multilevel inverters topologies have played the very important role due to their merits such as simplicity, highly effective, low switch usage and occupy less space [6], [7].…”

<p>Now a day the power demand has a major problem for developing countries due to the growth of population, industries, IT companies and other needs. In this present situation the fossil fuel-based power generation alone does not support the consumer needs, poor power quality due to nonlinear function and very harmful for environment. The main objective of this paper is improving the power quality of grid connected photovoltaic power system through a new cascade H-bridge multilevel inverter. The proposed research work has been modelled and controlled by ANFIS intelligence in MATLAB simulation environment. The simulation results are analysed under various operating conditions for improve the performance of proposed system. Finally, the proposed system THD value of simulation results is compared with IEEE 1547 standard for prove the effectiveness of proposed research work.</p>

“…Hydrogen fuel cells have become increasingly popular due to their environmental friendliness and maturing technologies for large-scale hydrogen production [1,2]. Fuel cell based power units have been used as power sources in applications, such as dispatchable clean energy sources in microgrids [3], uninterruptible power supply and onboard power source for automobiles [4]. For these applications, it is important to have an accurate model to represent the characteristics of the entire power module for system studies and effective control system designs.…”

High Fidelity Model for Proton Exchange Membrane Fuel Cell Power Module Considering Internal Power Losses

et al. 2018

A high‐fidelity model has been developed in this paper to characterize a proton exchange membrane (PEM) fuel cell power module. The uniqueness of this model is that it takes into account of the internal temperature of the stack and internal power consumptions by the auxiliary systems. To simplify the model representation, an equivalent circuit model is developed by using operating condition dependent fictitious circuit components. The parameters of these components are nonlinear functions of fuel cell operating conditions, most notably, the output power level and the stack temperature. The specific values of these parameters are determined through a series of experiments on a physical fuel cell power module. The data are then used to construct a nonlinear model to cover a wide fuel cell operating range. To validate the developed model, five characteristic features are used in the experiments. Comparing against the experimental results, it is shown that the developed model produces the minimal amount of errors in comparison with the theoretical model, and a previously developed model. When used to represent a physical fuel cell power source in practice, this model improves the quality of control system design and analysis.
