Analytical Modeling of Photovoltaic Systems Under Partial Shading Conditions Incorporating Bypass and Blocking Diodes Influence

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
This paper presents an innovative analytical model for photovoltaic (PV) systems operating under partial shading conditions (PSCs). The model is developed through a detailed analysis of the current–voltage (I–V) curves of PV systems affected by PSCs and employs a straightforward computational algorithm by adjusting every time the number of cells or ...

Analysis of Dynamic Characteristic for Solar Arrays in Series and Global Maximum Power Point Tracking Based on Optimal Initial Value Incremental Conductance Strategy under Partially Shaded Conditions

Energies, 2017
Partial shading (PS) is an unavoidable condition which significantly reduces the efficiency and stability of a photovoltaic (PV) system. With PS, the system usually exhibits multiple-peak output power characteristics, but single-peak is also possible ...

Enhancing Conventional Power Grids: Analyzing the Impact of Renewable Distributed Generation Integration Using PSO in the 118‐Bus IEEE System

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
Many traditional distribution systems (TDSs) flaws and weaknesses are fixed when renewable distributed generations (RDGs) is integrated into them. Some of the forces that have driven work on the integration of renewable sources into modern conventional power systems are the effective strategies for increasing system efficiency and reducing total cost ...

Performance Assessment and Design Recommendations of Nonisolated DC/DC Converters and Maximum Power Point Tracking Techniques for Standalone Photovoltaic Systems

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
A maximum power point tracking (MPPT) algorithm is mandatory to operate the system at its maximum power point (MPP) under different irradiance and temperature for improved efficiency. This requires an impedance‐matching mechanism in the form of a DC/DC converter between the photovoltaic (PV) modules and the load. Each MPPT algorithm and DC/DC converter
