“…The output power of the photovoltaic cell varies under different external factors such as light intensity, environment, and temperature, and there exists a maximum power output point. Maximum power point tracking technology enables the photovoltaic cell to operate at the maximum power point, effectively improving the output power of the photovoltaic cell [5][6].…”

Aim at the low efficiency of the traditional incremental conductance method and the insufficient adaptability of the orthogonal vector construction of the single phase locked loop, this paper introduces the incremental conductance method combined with the constant voltage method to achieve the maximum power point tracking (MPPT), and uses second-order generalized integrator based phase locked loop (SOGI-PLL) to construct the orthogonal components to achieve the phase locked. In Matlab/Simulink, a simulation model of the single-phase photovoltaic energy storage grid-connected inverter is constructed and simulated. The simulation results show that not only the bus voltage is stable, but also the grid-connected current is in phase with the grid voltage, and the value of THD meets the grid-connected requirements, which proves the effectiveness of the above control method.

“…In the case of partial modules of a PVMA under different shading situations, multiple peak values would occur on the P-V curves. Therefore, MATLAB R2022a/Simulink [26,27] was applied to build the PVMA model, which adopted SWM-20W photovoltaic modules produced by MPPTSUN Co. Ltd. (DongGuan, Guangdong Province, China) to form the test cases with a 4-serial-3-parallel module array, and the specifications for the single module are shown in Table 1 [28]. Figures 1 and 2 display the P-V and I-V curves derived from the simulation with a 4-serial-3-parallel PVMA under STCs (i.e., solar irradiance at 1000 W/m 2 , temperature at 25 • C and AM (air mass) at 1.5), where all modules were not shaded at all and the third photovoltaic module in the first series was under 50% shading.…”

In this paper, a method based on an improved intelligent bat algorithm (IIBA) in cooperation with a voltage and current sensor was applied in maximum power point tracking (MPPT) for a photovoltaic module array (PVMA), where the power generation performance of a PVMA was enhanced. Due to the partial shading of the PVMA from climate changes or the surrounding environment, multiple peak values were generated on the power–voltage (P-V) curve, where the conventional MPPT technology could only track the local maximum power point (LMPP), hence the reduction in output power of PVMAs. Therefore, the IIBA-based MPPT was proposed in this paper to solve such issues and to ensure the capability of a PVMA in tracking the global maximum power point (GMPP) and utilization for enhancing the output power of a PVMA. Firstly, the Matlab/Simulink software was used to establish a boost converter model that simulated the actual 4-series–3-parallel PVMA under different shaded conditions, where the P-V curve with 1-peak, 2-peak, 3-peak and 4-peak values were generated. Subsequently, the tracking paces of the conventional bat algorithm (BA) were adjusted according to the gradient of the P-V curve for a PVMA. At the same time, 0.8 times the maximum power point (MPP) voltage Vmp under standard test conditions (STCs) for a PVMA was set as the initial tracking voltage. Lastly, the simulation results proved that under different environmental impacts, the proposed IIBA led to better performances in tracking both dynamic and steady responses.

“…Advanced control architec- Different MPPT methods, such as P&O, IC, SMC and FLC, applied to a two-stage grid-connected PV system, show different THD. From a comparison on the THD level of the currents injected into the connection network, the FLC and SMC-based MPPT methods, the injected current's THD was 1.34% and 1.99% [60].…”

Grid converters play a central role in renewable energy conversion. Among all inverter topologies, the current source inverter (CSI) provides many advantages and is, therefore, the focus of ongoing research. This review demonstrates how CSIs can play a pivotal role in ensuring the seamless conversion of solar-generated energy with the electricity grid, thereby facilitating stable and reliable integration. This study extensively investigates various categories of single-stage CSI photovoltaic inverters, categorizing them into two-level, three-level, and multi-level architectures. Furthermore, these inverters are classified based on construction attributes, power factor, and total harmonic distortion values to assess their compliance with the standards, such as IEEE 1547 and IEC 61727. This review also delves into diverse control strategies for seamless grid integration. This comprehensive assessment serves as a resource for researchers in the field, enabling them to effectively choose the most suitable CSI for their specific applications. Additionally, it offers a quick reference point to steer research endeavors toward refining the integration of CSIs within photovoltaic systems.
