“…The partial gas pressures of hydrogen and oxygen, composition, temperature difference, and moisture content of the membrane are just a few of the numerous variables that greatly influence how much power the PEMFC [ 37,38 ] can produce when it is required. A PEMFC system can only produce its maximum power at one specific point on the power–current curve, known as the MPP, [ 39–41 ] for fixed operating circumstances.…”

The proton exchange membrane fuel cell (PEMFC), one of the many fuel cell varieties on the market, is distinguished by its low temperatures of operation, high reliability, and extended lifespan. The fuel cell system's maximum output can only be achieved at one specific operating point under varying operating circumstances. Hence, it is essential to get the most power possible from the PEMFC for improved functioning and optimal exploitation of grid systems. Thus, the design of a maximum power point tracking (MPPT) controller for a PEMFC power system using an amplified salp swarm optimization (AS2O) algorithm is focused on. Here, an interleaved Luo converter is also used to produce a regulated output voltage with less switching stress and frequency. Moreover, the proposed work intends to effectively satisfy the energy demand of grid systems by obtaining the maximum electrical energy from the PEMFCs with less harmonics and low system complexity. The simulation and performance results of the proposed AS2O‐MPPT controlling model are validated and compared using several parameters using MATLAB/Simulink tool. Using the proposed controlling technique, the total harmonics distortion is reduced up to 1.16%, with the settling time of 0.0062 s, rise time of 0.0010 s, and peak overshoot of 0.255 W.

“…Thus, the DC-link voltage controller for the three-phase system is represented by the block diagram as shown in Figure 3. Considering the DC-link voltage PI controller (PI), the open-loop and the closed-loop transfer functions can be represented, respectively, by (22) and (23).…”

“…Bengourina et al [19] presented a Kalman observer, to estimate the PV parameters like voltage and current, thus reducing the number of physical sensors and giving input to the MPPT algorithm [20], [21] to have the maximum power from PV. It is worth mentioning that in [22], a fixed value of grid voltage is used to generate the reference active current, which is not adaptable for any variation in voltage at POI. Based on the paper [23], [24], decoupling capacitor DC voltage is estimated based on solar PV parameters and fixed grid voltage, whereas DC voltage estimation proposed in this paper using solar PV parameters and peak amplitude of the voltage at the point of interface between grid and load.…”

<a name="_Hlk98601430"></a><span lang="EN-US">In this research, a sensor free DC-link voltage controller based multifunctional inverter is proposed for a two-stage three-phase grid-connected solar photovoltaic (PV) system. First, the proposed scheme consists of an outer voltage controller requiring DC-link voltage knowledge, has the ability to manage power-sharing between the PV system and the utility grid, and second, has the ability of the VSI to act as a compensator for harmonics in the grid current polluted by non-linear loads. The suggested active power controlling grid reference current signal scheme replaces the standard controller, requiring the high voltage sensor to sense DC-link voltage, which is pricey, increasing the hardware complexity and reducing reliability. The performance of the proposed active power management approach is comparable to that of a conventional voltage sensor-based voltage controller. The effectiveness of the proposed method for two stage three-phase grid-connected solar PV system under fixed and variable irradiance feeding nonlinear loads is rigorously verified using MATLAB/Simulink software</span><span lang="EN-US">.</span>
