A Multi-Start Greedy Algorithm for Optimal Reconfiguration of Solar Photovoltaic Arrays for Maximum Power Output in Real-Time Application

摘要

In this paper, a method for solving the problem of the optimal configuration of PV panels during connectivity under real-time operating conditions for maximum power output in large PV installations is presented. The problem considers the optimal configuration of the PV panels during connectivity based on the choice of panels in series and in parallel. The optimal configuration problem is a non-linear mixed integer problem where the number of 0-1 integer variables is equal to the product of the number of panels and the number of subsets where the panels have to be assigned. This makes it difficult to be solved in real-time for reconfiguring the connection of panels. In this work, a local search greedy algorithm is proposed to allow a fast solution of the problem in real-time which necessitates the formulation of a fast linear solver. Finally, the proposed solution is validated through simulation.
