Abstract:
Energy demand forecasted for the next several years has been bench-marked due to the massive
need for electrical energy. Solar power plants have earned a great marketplace in the following
years, but it also faces challenges in terms of power dissipation due to the frequent occurrence
of shade. As a result, per unit of solar electricity price increases drastically. There is an
immense need to ensure a maximum dependable power conversion efficiency of Photovoltaic
(PV) systems by mitigating power output losses during partial shading conditions.
Reconfiguration of PV arrays is a useful, effective, and promising approach in this context.
Though several reconfiguration techniques have been developed in recent years, their
applicability to real-time power plants is debatable due to the requirement of a large number of
physical relocations, long interconnecting ties, and complexity. A novel row index
mathematical procedure is proposed followed by a technique in which the reconfiguration
matrix indexes are filled with a unique number so that no row number repeats in the same row
and column. To propose a new topology, comparative analysis has been done on the very recent
techniques such as Sudoku, TCT, Chess-Knight, and PSO-based reconfiguration on five
different shading patterns. It has been observed that approximately 68 % power loss is
mitigated in TCT configuration. It is worth noting that it results in higher PV output power
than existing latest reconfiguration techniques such as PSO, chess knight, Sudoku, and others
