In this paper, a variable step size IC MPPT controller for the proton exchange membrane fuel cell (PEMFC) power system is proposed. The efficiency of the proposed algorithm has been studied successfully using a 7 kW PEMFC fed by DC‐DC boost converter derived using the proposed MPPT controller implemented under Matlab/Simulink environment. Comparison results obtained using both implemented fixed and variable step size IC MPPTs on two scenarios test considering temperature and hydrogen pressure variation show that the proposed variable step size IC MPPT outperforms the conventional fixed step size in static and dynamic performances.

“…Thus, humidity control becomes critical to avoid undesirable nonlinear behavior [21]. To identify the optimal operating range and verify the performance of FC against the real data, a comprehensive model with the reflection of multi-physics behavior is required [22]. In this work, a model has been developed based on the laws of thermodynamics, kinetics, and electrochemistry already deduced in previous work [23].…”

Fuel cell (FC)-driven railroad propulsion systems (RPSs) have been much appreciated for the past two decades to get rid exhausts of fossil fuels, but the inability of FCs to capture regenerative power produced by propulsion systems during regenerative braking and the dependency of its power density on operating current density necessitates the hybridization of FCs with batteries and/or supercapacitors to utilize the best features of all three power sources. Contrary to the research trend in hybridization where the purpose of hybridization such as fuel saving, high efficiency, or high mileage is achieved by certain operational algorithms without going into detail models, this study using detailed models explores the impact of high-power charging limitations of batteries on the optimization of hybridization, and proposes a solution accordingly. In this study, all three power sources were modeled, the optimal and suboptimal behaviors at the individual level were identified, and power distribution was implemented for a propulsion system, as recommended by the optimal features of all individual power sources. Since the detailed modeling of these power sources involves many mathematical equations and requires the implementation of continuous and discrete states, this study also demonstrates how, using C-MEX S-Functions, these models can be implemented with a reduced computational burden.

“…Authors in [5] developed a MATLAB simulation model of grid connected FC-PV hybrid system. It can be concluded that extensive study has been reported in literature related to modeling, optimization and energy management for FC-PV hybrid systems [6][7][8][9][10][11][12]. It is evident from the literature that fuel cells along with solar have a huge potential for emission free power generation for small houses, commercial building, offices etc.…”

Renewable energy has become very popular in recent years. The amount of renewable generation has increased in both grid-connected and stand-alone systems. This is because it can provide clean energy in a cost-effective and environmentally friendly fashion. Among all varieties, photovoltaic (PV) is the ultimate rising star. Integration of other technologies with solar is enhancing the efficiency and reliability of the system. In this paper a fuel cell–solar photovoltaic (FC-PV)-based hybrid energy system has been proposed to meet the electrical load demand of a small community center in India. The system is developed with PV panels, fuel cell, an electrolyzer and hydrogen storage tank. Detailed mathematical modeling of this system as well as its operation algorithm have been presented. Furthermore, cost optimization has been performed to determine ratings of PV and Hydrogen system components. The objective is to minimize the levelized cost of electricity (LCOE) of this standalone system. This optimization is performed in HOMER software as well as another tool using an artificial bee colony (ABC). The results obtained by both methods have been compared in terms of cost effectiveness. It is evident from the results that for a 68 MWh/yr of electricity demand is met by the 129 kW Solar PV, 15 kW Fuel cell along with a 34 kW electrolyzer and a 20 kg hydrogen tank with a LPSP of 0.053%. The LCOE is found to be in 0.228 $/kWh. Results also show that use of more sophisticated algorithms such as ABC yields more optimized solutions than package programs, such as HOMER. Finally, operational details for FC-PV hybrid system using IEC 61850 inter-operable communication is presented. IEC 61850 information models for FC, electrolyzer, hydrogen tank were developed and relevent IEC 61850 message exchanges for energy management in FC-PV hybrid system are demonstrated.
