PV systems essentially depend on insolation and temperature; but partial shading phenomenon defects characteristics of PV systems significantly. Unlike under ideal condition that PV system has only one maxima, it has several locals under partial shading (with only one global maxima). Conventional Maximum Power Point Trackers (MPPTs) easily fail to track real optimum point and are trapped at locals...
In this paper, the single-input fuzzy logic controller (FLC) (SIFLC) for boost converter output-voltage regulation is proposed. The SIFLC utilizes the signed distance method that reduces the multidimensional rule table to 1-D with only one input variable, i.e., distance . The simplification allows for the control surface to be approximated by a piecewise linear. It is shown that, despite the simplicity...
Photovoltaic (PV) system performance extremely depends on local insolation and temperature conditions. Under partial shading, P-I characteristics of PV systems are complicated and may have multiple local maxima. Conventional Maximum Power Point Tracking (MPPT) techniques can easily fail to track global maxima and may be trapped in local maxima under partial shading; this can be one of main causes...
