“…5 and output V-I characteristic of (13), verified experimentally and reported in [30] is used. Similar characteristic is given for all FCs in [26][27][28] FCs have several shortcomings [28] such as no energy storage possibility, slow dynamic response, output voltage fluctuation with load and difficult cold start. Therefore, an electric storage such as battery or ultracapacitor must be accompanied with FC to improve its dynamic characteristics.…”

“…From the empirical point of view, [27] formulated a model that enables simulation of the V-I curve of FCs in typical conditions. Different from the normal PEMFC model, a purely electronic circuit model similar to characteristics of a PEMFC was introduced in [28] that can be used to design and analyze FC power systems using electric circuit elements. As an experiment, the steady-state performance and transient response for hydrogen and oxygen flow in PEMFCs is investigated in [29].…”

“…Therefore, an electric storage such as battery or ultracapacitor must be accompanied with FC to improve its dynamic characteristics. If the storage is in parallel directly with the DC bus, its charge and discharge cannot be controlled [28]; therefore, a bidirectional converter is needed between the DC bus and the electric storage to control its state of charge. A detailed control basics and algorithm for the bidirectional converter of the storage is presented and verified in [31].…”

1 Abstract-This paper shows how the power quality can be improved in a microgrid that is supplying a nonlinear and unbalanced load. The microgrid contains a hybrid combination of inertial and converter interfaced distributed generation units where a decentralized power sharing algorithm is used to control its power management. One of the distributed generators in the microgrid is used as a power quality compensator for the unbalanced and harmonic load. The current reference generation for power quality improvement takes into account the active and reactive power to be supplied by the micro source which is connected to the compensator. Depending on the power requirement of the nonlinear load, the proposed control scheme can change modes of operation without any external communication interfaces. The compensator can operate in two modes depending on the entire power demand of the unbalanced nonlinear load. The proposed control scheme can even compensate system unbalance caused by the single-phase micro sources and load changes. The efficacy of the proposed power quality improvement control and method in such a microgrid is validated through extensive simulation studies using PSCAD/EMTDC software with detailed dynamic models of the micro sources and power electronic converters.

“…There are many electrical circuit models [11][12][13][14][15]. However, nearly all of the circuit models are formed empirically, which means that all parameters of the circuit must be determined by experimentation and are expected to change under different operating conditions due to the nonlinearity of the fuel cell.…”

An Equivalent Electrical Circuit Model of Proton Exchange Membrane Fuel Cells Based on Mathematical Modelling

et al. 2012

Many of the Proton Exchange Membrane Fuel Cell (PEMFC) models proposed in the literature consist of mathematical equations. However, they are not adequately practical for simulating power systems. The proposed model takes into account phenomena such as activation polarization, ohmic polarization, double layer capacitance and mass transport effects present in a PEM fuel cell. Using electrical analogies and a mathematical modeling of PEMFC, the circuit model is established. To evaluate the effectiveness of the circuit model, its static and dynamic performances under load step changes are simulated and compared to the numerical results obtained by solving the mathematical model. Finally, the applicability of our model is demonstrated by simulating a practical system. Keywords

In this paper, a novel semi-empirical modeling method to mathematically derive a nonlinear equivalent circuit from a special group of impedance fuel cell models is proposed. As an example, a 5-cm 2 direct methanol fuel cell (DMFC) was modeled by this method. The derived equivalent circuit is composed of lumped nonlinear resistors, capacitors and an inductor. The nonlinear circuit has an impedance equivalent to the target fuel cell in various operating conditions and provides a good approximation of the static and transient behaviors of the fuel cell. The equivalent circuit fuel cell model was validated by comparing its numerical simulation results with its polarization curve and the dynamic behavior of the target DMFC. These comparisons were performed while the DMFC was operated under square current pulses with different upper and low current levels.
