“…Solar photovoltaic (PV) systems have become an increasingly popular and cost effective means of generating renewable energy [1]- [3]. However, the efficiency of these systems can be limited by various factors, including suboptimal performance of the maximum power point tracking (MPPT) control algorithm [4]- [6]. MPPT is a critical function in photovoltaic systems that ensures that the output power of the PV array is maximized by continuously adjusting the operating point of the system [7]- [11].…”

With the growing demand for renewable energy, solar photovoltaic (PV) systems have gained popularity as a reliable source of clean electricity. However, the performance of these systems can be limited by factors such as suboptimal maximum power point tracking (MPPT) algorithms. In order to improve the power generation efficiency of PV systems, it is important to evaluate the performance of dynamic MPPT algorithms that can adapt to varying operating conditions. Traditionally, such evaluations have been time consuming and expensive, often requiring extensive testing and measurement equipment. In this paper, we propose a novel approach to evaluate dynamic MPPT performance very quickly and simply using PSIM software. This approach enables accurate and efficient evaluation of MPPT performance under a wide range of operating conditions, while minimizing the cost and time involved in traditional testing methods. When applying the proposed method to a 3.7 kW inverter using the traditional perturbation and observation (P and O) method, we found that the highest average efficiency was 98.92% at an MPPT control period of 0.1s and a voltage perturbation of 1 V. This evaluation technique provides valuable insights into the design and optimization of more efficient MPPT control algorithms, leading to improved power generation efficiency and increased adoption of solar PV systems.

“…The PV solar arrays absorb the sunlight and generate electricity into the power grids [2]. Various control techniques of PV systems [3] like the maximum power point tracking (MPPT) control [4][5][6][7][8][9][10][11][12], solar tracker [13], power quality and reactive injection capability [14], anti-islanding [15][16][17][18], and fault detection and diagnosis [19,20] are developed to support the solar power generation to become more competitive. Electricity production from PV solar arrays depends very much on environmental and weather conditions, such as solar radiation and ambient temperature [21][22][23][24][25][26][27][28][29][30].…”

Solar photovoltaic (PV) generation suffers from multiple serious issues, for example shading effects directly affect the performance of installed PV arrays. By studying these issues, it can play a key role in improving the limitations and performance of PV panels. The study of PV arrays under partial shading conditions is mentioned in many papers as a part of other studies and as an independent phenomenon. Therefore, it is essential to improve these studies and update them with new research and study this problem in detail to know how to limit the effects of partial shading irradiance conditions on PV arrays performances, including economical aspects. This paper proposes to study the effects of different partial shading irradiance conditions for a PV array in various configurations. The analysis is proved in detail through the simulation of the proposed PV array in the Matlab/Simulink environment. The obtained results show the performances of interconnected PV arrays under different partial shading irradiance and temperature conditions, including the solar array I-V and P-V characteristics. In addition, different PV array configurations with and without bypass and blocking protection diodes improve and minimize the effect of partial shading conditions and avoid the reductions in output power.
