“…The results showed that a chattering reduction of 84% could be achieved using the proposed technique. Ceran and Orłowska [28] investigated the decline of power source performance in a hybrid power system based on a multi-criterion analysis of load distribution. The authors introduced a mathematical model intended for planning cooperation in a hybrid power system consisting of photovoltaic panels, wind turbines, and a discrete regenerative fuel cell.…”

As a result of global energy demand increase, concerns over global warming, and rapid exhaustion of fossil fuels, there is a growing interest in energy system dependence on clean and sustainable energy resources. Attractive power technologies include photovoltaic panels, wind turbines, and biomass power. Fuel cells are also clean energy units that substitute power generators based on fossil fuels. They are employed in various applications, including transportation, stationary power, and small portable power. Fuel cell connections to utility grids require that the power conditioning units, interfacing the fuel cells and the grids, operate accordingly (by complying with the grid requirements). This study aims to model a centralised, single-stage grid-tied three-level diode clamped inverter interfacing a multi-stack fuel cell system. The inverter is expected to produce harmonic distortions of less than 0.5% and achieve an efficiency of 85%. Besides the grid, the system consists of a 1.54 MW/1400 V DC proton exchange membrane fuel cell, a 1.3 MW three-level diode clamped inverter with a nominal voltage of 600 V, and an inductance-capacitance-inductance (LCL) filter. Two case studies based on the load conditions are considered to assess the developed system’s performance further. In case 1, the fuel cell system generates enough power to fully meet this load and exports the excess to the grid. In the other case, a load of 2.5 MW was connected at the grid-tied fuel cell inverter’s output terminals. The system imports the grid’s power to meet the 2.5 MW load since the fuel cell can only produce 1.54 MW. It is demonstrated that the system can supply and also receive power from the grid. The results show the developed system’s good performance with a low total harmonic distortion of about 0.12% for the voltage and 0.07% for the current. The results also reveal that the fuel cell inverter voltage and the frequency at the point of common coupling comply with the grid requirements.

“…The modelling techniques of hybrid systems presented in the above mentioned works do not take into account the decrease in stack efficiency after years of operation. Consequently, in such a hybrid system, energy imbalance may occur [24], which will result in increased consumption from the power grid [9].…”

The article presents mathematical model designed to estimate the rate of performance decrease in fuel cell stack. The fuel cell stack performance decrease rate is determined on the basis of stack average voltage measurements. The proposed model is used to determine power curve as well as exploitation indicators of fuel cell stack with a nominal power of 50 kW after 14 000 hours of continuous operation. The model is also used to determine the average voltage drop for the eleven-year fuel cell stack with a nominal power of 1,2 kW. In both studies, the values of exploitation indicators as well as their differences in relation to nominal values are determined.

“…The newly-developed testbed allows achieving the parameters used in similar research (ball speed and the impact force) [11]. Most studies simulate the effects of hail using pneumatic equipment that provides the energy needed to move a piece of ice [2,4,[32][33][34][35][36]. The hail test requires expensive, time-consuming equipment.…”

The impact of hail ice cubes on composite structures (such as solar cells) causes actual defects. This article presents a series of tests, in which solar cell modules were exposed to hail simulation testbed balls, allowing to assess the following: the impact energy, which causes the major defects in solar cells; the formed micro-cracks in the structure of solar cells, resulting in the loss of power generated by a solar cell; and the solar cell parameters necessary for modelling. In addition, this article presents a digital analysis of hail simulation. Information received from the digital analysis was used to optimize the structure of solar cells in order to improve its resistance properties. The aim of this study was to present a simple method for experimental hail simulation. The proposed hail impact estimation method can be successfully applied to study the influence of the mechanical–dynamic impact of photovoltaic (PV) modules of different structures on the technical characteristics of these modules (structural stability, power generation, etc.). The study showed that PV modules are subjected to an irreversible effect of the excitation force (i.e., micro-cracking) and it can reduce the generated power by 2.33% to 4.83%.
