English Abstract

In this article, a novel continuous control set model predictive control (CCS–MPC) is proposed for an LC-filtered three-phase three-level four-wire voltage-source inverter (3P-4W-3L-VSI). The proposed MPC algorithm provides independent control of each phase of the 3P-4W-3L-VSI under various unbalanced load conditions, which shows superior performance under unbalanced loads. Furthermore, different ...

该研究针对三电平拓扑及模型预测控制(MPC)的优化,与阳光电源的核心产品线高度契合。在组串式逆变器和大型集中式逆变器中,三电平拓扑是提升效率和功率密度的关键。CCS-MPC相比传统有限控制集MPC,能有效降低开关频率波动并改善谐波性能,对提升阳光电源逆变器在复杂电网环境(如不平衡负载、弱电网)下的适应性具有重要参考价值。建议研发团队关注该算法在iSolarCloud智能运维平台下的实时计算负载优化,并探索其在PowerTitan等储能变流器中实现更平滑功率输出的应用潜力。
