A photovoltaic array is subject to reduction of output caused by partial shading which causes bypass diodes turn on. This can be alleviated partly or fully cross-tying the modules within rows array, and reconfiguring positions it. In this paper a PV reconfiguration algorithm based on magic square proposed. The reconfigured has effects more evenly dispersed over entire surface, reduces voltage current drop due diode conduction. performance scheme assessed using simple models patterns,...

This paper presents a particle swarm optimization (PSO) technique for the maximum power point tracking of PV generation system under unequal solar irradiation.The consists multiple PV-Ćuk converter (PVCC) modules in series chain and terminal step-up load connection.The bidirectional Ćuk each PVCC has two panels connected at its four terminals.The configuration offers advantage that shading or module mismatching, provides current bypass which can allow track their available power.The new...

The imperative of effecting a worldwide shift towards renewable, carbon-neutral energy generation has risen to the forefront contemporary priorities. Consequently, numerous methodologies have been devised enhance efficiency renewable sources. Solar PV technology, in particular, gained significant prominence as pivotal power method. This paper introduces an innovative approach that combines Series and Parallel Differential Power Processing (SP-DPP) converters within small-scale array...

A scheme is proposed for maximum power point tracking in series-parallel photovoltaic arrays using differential processing, based on bidirectional Cuk converters and inverted buck adjusting module current voltage respectively. Converter transfer functions are derived linearization state space time averaging. These used to develop design criteria well-behaved transient response, reduction of the effect non-minimum phase. representative with about 10 ms settling presented. It shown that this...

In recent years, there has been an increasing interest in utilising Differential Power Processing converters (DPP) Photovoltaic (PV) applications to achieve the maximum power point tracking (MPPT), minimum losses and high efficiency under unequal lighting conditions.This paper presents a novel Series Parallel (SP) DPP scheme, with proper control technique optimise system output mismatch conditions compared that of conventional 2×2 SP array which is protected bypass diodes.The simulation...
