在过去的几年中，在快速变化的辐照度条件下优化光伏系统的能量收集一直是研究和公司之间竞争的活跃领域。所提出的快速最大功率点跟踪（MPPT）算法可以产生功率半导体的极其可变的负载，从而导致系统寿命的减少，这因此可以抵消更高能量收集的经济优势。这项工作通过深入的理论和实验室工作分析了这个问题。然后，一个多目标MPPT，它限制了正温度梯度和功率半导体的最大结温，并在实验室中进行了充分的验证与使命档案模拟可变的辐照度条件。
In the last years, the optimization of the energy harvesting of photovoltaic systems during fast variable irradiance conditions has been an active area of research and of competition among the companies. The proposed fast maximum power point tracking (MPPT) algorithms can produce extremely variable loading of the power semiconductors resulting in a decrease of the system lifetime, which in consequence can nullify the economic advantage of higher energy harvesting. This work analyzes the problem with a deep theoretical and laboratory work. Then, a multiobjective MPPT, which limits the positive temperature gradient and the maximum junction temperature of the power semiconductors, is introduced and fully validated in the laboratory with a mission profile emulating variable irradiance conditions.
