Dandelion Optimizer Algorithm Based Optimal Photovoltaic Array Reconfiguration under Partial Shading Condition

In this paper, a reconstruction method based on improved dandelion optimizer (DO) is proposed for the grid connection topology. The row current of the photovoltaic array is balanced by changing the electrical connection inside the photovoltaic array to evenly distribute the shadows on the photovoltaic array. In the four shadows of 10×10 PV array, DO and TCT algorithm are compared by mismatch loss. The results show that DO can effectively improve the output power of photovoltaic array, reduce the mismatch loss, the output PV curve tends to show a single peak, and the reconstruction results are better than TCT.
