Abstract

Information system data transmission delays, packet loss, and bit errors will cause the information collected by the distribution network control center to deviate from the true value, and as the information failure problem intensifies, the original optimized control strategy cannot meet actual needs. A predictive control method considering the information failure of the distribution network under the cyber-physical fusion system is proposed. Aiming at the information failure problem in CPS, the information elements, routing model and link model are established. Then, combining with the real-time dispatching process of distribution network, a coordination optimization model of active distribution network considering information failure is proposed to minimize the cost. Predictive control model is used to adjust various distributed energy sources. Finally, through the simulation analysis of the improved IEEE33-node distribution network, the feasibility and effectiveness of the proposed method are verified, and the difference of different information failure cases is analyzed.

考虑信息失效的有源配电网预测控制方法

信息系统数据传输延迟、丢包、误码等都会导致配电网控制中心采集到的信息偏离真实值，随着信息失效问题的加剧，原有的优化控制策略已不能满足实际需要。提出了一种考虑信息物理融合系统下配电网信息失效的预测控制方法。针对CPS中的信息失效问题，建立了信息要素、路由模型和链路模型。然后，结合配电网的实时调度过程，提出了考虑信息失效的主动式配电网协调优化模型，以实现成本最小化。采用预测控制模型对各种分布式能源进行调节。最后，通过对改进后的ieee33节点配电网进行仿真分析，验证了所提方法的可行性和有效性，并分析了不同信息故障情况下的差异。
