Power Flow Rolling Optimization Control Strategy for Modular Power Architecture
为提高动力系统的实时工作性能，提出了一种由动力模组、储能单元以及能量转换组成的模块化动力系统。以实现动力系统实时工作效率最优为目标开展了动力系统的控制方法研究，获得了基于规则为主的动力系统功率流控制策略进而实现了动力系统的合理功率分配以及效率提升。针对功率流控制的动力单元工作时间占比分配不均的问题，提出了滚动优化控制策略，分别开展了基于固定位次的顺序滚动优化控制策略以及基于累计工作时间的排序滚动优化控制策略研究。研究结果表明，应用上述两种滚动优化策略均能实现动力单元的工作时间均匀化从而提升动力系统的耐久性，且基于累计工作时间的排序滚动优化策略的优化效果更好。
To improve the real-time performance of the power system, a modular power architecture composed of power modules, energy storage units, and energy conversion is proposed. The research on control methods for power systems was carried out with the goal of achieving optimal real-time work efficiency, and a rule-based power flow control strategy for power systems was obtained, thereby achieving reasonable power allocation and efficiency improvement in the power system. A rolling optimization control strategy is proposed to address the issue of uneven distribution of working time in power flow control power units. Research has been conducted on fixed order rolling optimization control strategies and cumulative working time based sorting rolling optimization control strategies. The research results indicate that both of the above two rolling optimization strategies can achieve uniform working time of the power unit and improve the durability of the power system, and the optimization effect of the sorting rolling optimization strategy based on cumulative working time is better.
