Renewable and Sustainable Energy Reviews, 2016
Abstract The objective of this paper is to present a survey of the Perturbed-based Extremum Seeking Control (PESC) methods and their applications in Photovoltaic (PV) arrays under Partially Shaded Conditions (PSCs). A new PESC scheme is also proposed to seek and track the Global Maximum Power Point (GMPP) of the PV power.

A hybrid intelligent GMPPT algorithm for partial shading PV system
Control Engineering Practice, 2019Abstract Maximum power extraction for PV systems under partial shading conditions (PSCs) relies on the optimal global maximum power point tracking (GMPPT) method used. This paper proposes a novel maximum power point tracking (MPPT) control method for PV system with reduced steady-state oscillation based on improved particle swarm optimization (PSO ...

IEEE Transactions on Sustainable Energy, 2022
Conventional global maximum power point tracking (GMPPT) algorithms show limited tracking speed and accuracy due to the unnecessary peak search considering the complexity of partial shading conditions (PSCs). This paper proposes a novel power incremental (PI) algorithm for photovoltaic GMPPT and partial shading detection with the aid of the reference ...

An improved sliding mode control–based GMPPT algorithm for photovoltaic system
Transactions of the Institute of Measurement and Control, 2023In this paper, an improved fixed-frequency-based integral sliding mode controller is designed and applied to a stand-alone photovoltaic (PV) system to obtain the desired reference signal for the maximum power point tracking. The proposed technique is designed with the modified sliding surface and sigmoidal function-based control law which improves the

A High-speed GMPPT Method Under Gaussian Laser Beam Conditions
2020 IEEE Applied Power Electronics Conference and Exposition (APEC), 2020Under Gaussian laser beam conditions (GLBC), multiple peaks are observed in the power-voltage (P-V) curve of a photovoltaic (PV) array, and a conventional maximum power point tracking (MPPT) algorithm is not suitable for both tracking accuracy and tracking speed.

An Improved GMPPT Technique Under Partial Shading Conditions for PV Array
2019 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC), 2019PV solar is widely establishing technology which is considered as a promising source to replace the conventional technologies. But it has limited usage due to its limitations such as low efficiency, invariable nature etc. The efficiency of PV array is affected by one such factor that is called as partial shading condition.

New GMPPT algorithm for PV arrays under partial shading conditions
2012 IEEE International Symposium on Industrial Electronics, 2012This paper proposes a two-stage algorithm to track the global maximum power point (GMPP) in non-uniform irradiance conditions. It uses randomly selected sample points on the P-V curve and corresponding power contours on the I-V curve to narrow down the search interval.
