Research on distributed multi-peak maximum power tracking control

When the photovoltaic(PV) array in partial shadow occlusion, the output characteristic curve will become more complex, the P-V curve showed multi peak, I-V curve into a step shape, making the output power of the PV array decreased. For realization of PV array maximum power tracking control technique for optimization, the first of different temperature, illumination, occlusion model of PV array are modeled and analyzed, the output characteristic curve, in-depth analysis of the block pattern of global location of the maximum power point, proposes a distributed maximum power tracking method, qualitative to solve the fall into the local maximum and makes the tracking failure problem and improve the PV array Output power, which provides a new idea for the research of the maximum power point tracking technology under multiple peaks.
