Fast and precise global maximum power point tracking techniques for photovoltaic system [PDF]

open access: yesIET Renewable Power Generation, 2019
The multiple power peaks obtained in the power–voltage ( P‐V ) curve of a photovoltaic string under partially shaded condition results in a complicated maximum power point tracking (MPPT) process. Under this condition, the conventional MPPT methods are not acknowledged as they result in false

Generic maximum power point tracking controller for small-scale wind turbines [PDF]

open access: yes, 2012
The output power of a wind energy conversion system (WECS) is maximized if the wind rotor is driven at an optimal rotational speed for a particular wind speed. To achieve this, a Maximum Power Point Tracking (MPPT) controller is usually used.

Experimental evaluations of global maximum power point tracking approaches in partial shading conditions

open access: yes2017 IEEE International Conference on Environment and Electrical Engineering and 2017 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2017
Maximum power point tracking (MPPT) under partial shading conditions (PSC) has been popular topic recently. In this paper, P&O algorithm, full scanning and large scanning methods and a novel method are evaluated experimentally. In order to compare the methods and algorithms considered, a single ended primary inductance converter (SEPIC) was set up ...

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Global maximum power point tracking in partially shaded PV systems using plant reproduction algorithm

open access: yesIET Renewable Power Generation, 2021
The power–voltage curve of photovoltaic (PV) power generation system under partial shading conditions (PSC) is non‐monotonic with multiple power peaks and traditional methods do not guarantee global convergence which leads to energy loss.
