“…The hydrogen produced passes through a bubbler (3) and a flash arrestor (11) to introduce it into the internal combustion engine through the intake manifold. Sensors (4-7) are monitored by the acquisition system (8), and actuators (9) and (10) are controlled by the engine control unit (ECU).…”

“…They are also static models, so they are not suitable for application to control techniques. In the research presented by the authors in [5,9,10], the electrolyzer is considered as a part of a more extensive system (i.e., solar renewable energy systems, wind energy). In these works, the authors proposed control strategies in which they use a static model to determine hydrogen production.…”

Experimental Study on the Performance of Controllers for the Hydrogen Gas Production Demanded by an Internal Combustion Engine

This work presents the design and application of two control techniques—a model predictive control (MPC) and a proportional integral derivative control (PID), both in combination with a multilayer perceptron neural network—to produce hydrogen gas on-demand, in order to use it as an additive in a spark ignition internal combustion engine. For the design of the controllers, a control-oriented model, identified with the Hammerstein technique, was used. For the implementation of both controllers, only 1% of the overall air entering through the throttle valve reacted with hydrogen gas, allowing maintenance of the hydrogen–air stoichiometric ratio at 34.3 and the air–gasoline ratio at 14.6. Experimental results showed that the average settling time of the MPC controller was 1 s faster than the settling time of the PID controller. Additionally, MPC presented better reference tracking, error rates and standard deviation of 1.03 × 10 − 7 and 1.06 × 10 − 14 , and had a greater insensitivity to measurement noise, resulting in greater robustness to disturbances. Finally, with the use of hydrogen as an additive to gasoline, there was an improvement in thermal and combustion efficiency of 4% and 0.6%, respectively, and an increase in power of 545 W, translating into a reduction of fossil fuel use.

Assessment of Wind Energy Potential for the Production of Renewable Hydrogen in Sindh Province of Pakistan

In this study, we developed a new hybrid mathematical model that combines wind-speed range with the log law to derive the wind energy potential for wind-generated hydrogen production in Pakistan. In addition, we electrolyzed wind-generated power in order to assess the generation capacity of wind-generated renewable hydrogen. The advantage of the Weibull model is that it more accurately reflects power generation potential (i.e., the capacity factor). When applied to selected sites, we have found commercially viable hydrogen production capacity in all locations. All sites considered had the potential to produce an excess amount of wind-generated renewable hydrogen. If the total national capacity of wind-generated was used, Pakistan could conceivably produce 51,917,000.39 kg per day of renewable hydrogen. Based on our results, we suggest that cars and other forms of transport could be fueled with hydrogen to conserve oil and gas resources, which can reduce the energy shortfall and contribute to the fight against climate change and global warming. Also, hydrogen could be used to supplement urban energy needs (e.g., for Sindh province Pakistan), again reducing energy shortage effects and supporting green city programs.

“…The optimization results indicated that diesel, PV and wind generator as a hybrid system provides a sustainable power for remote areas, but it has the highest capital cost among other considered scenarios [18]. The detail design and operation of PV and battery DC-DC converters as a standalone DC microgrid for remote community application is discussed in [19][20][21]. In these papers battery is considered as the main components for keeping DC bus voltage constant by charging and discharging functions.…”

The recent evolution in technology and lifestyle has been led to a dramatic increase in electricity demand so that the local communities are encountered with challenges of huge initial costs, and sustainable extension to a national grid. Here in this paper, a DC microgrid cluster with three small areas (A, B and C) is proposed. Control and power stability of small-scale electrical system using renewable resources is a big challenge. In this study, the operation of DC microgrid and behavior of the system at different operating conditions is evaluated under different condition of the solar radiation and temperature changes for specific time periods. The DC Converters with PI control strategies are integrated to control the system performance and load-power balancing. The DC bus voltage level is employed as an information carrier for controller to maintain operation stability, improve efficiency, and enhance the redundancy of a system. At the meanwhile, the Maximum Power Point Trucking Incremental Conductance (MPPT-IC) algorithm is applied to maximize the efficiency and regulate the output voltage of the PV system to desired DC bus voltage. The PV arrays with battery and bidirectional converter are simulated to overcome the intermittency problems of PV outputs. Some typical operation modes are simulated using MATLAB R /Simulink to confirm the proposed model preference compared to the literature.
