摘要:

目的 为解决传统一致性算法在微电网优化调度中,分布式单元之间需要进行频繁信息交换和系统拓扑结构变化引起的不稳定性问题,提出了一种改进动态事件触发机制一致性算法。 方法 改进动态事件触发机制中触发条件的阈值函数,使分布式单程中触发条件的阈值函数根据分布式单元的状态动态变化,确保分布式单元只在满足触发条件时进行信息交换。 结果 该算法在微电网结构拓扑发生变化及分布式单元“即插即用”时,在保证系统稳定的前提下,各分布式单元状态能够收敛一致,可大幅减少各分布式单元的通信次数。 结论 改进动态事件触发一致性算法在微电网经济调度中的应用不仅提高了系统的稳定性和可靠性,而且显著节约了通信资源,满足微电网经济性要求,具有较高的实用价值。

Abstract:

Objectives To address the instability issues in traditional consensus algorithms for microgrid optimization scheduling, caused by frequent information exchanges among distributed units and changes in system topology. An improved dynamic event-triggered mechanism consensus algorithm is proposed. Methods The threshold function in the triggering condition of the improved dynamic event-triggering mechanism is modified to enable dynamic adjustment based on the states of distributed units. This ensures that information exchange occurs only when the triggering condition is satisfied. Results The proposed algorithm ensures system stability during changes in microgrid topology and plug-and-play operation of distributed units. It achieves state convergence and consistency among distributed units while significantly reducing communication frequency. Conclusions The application of the improved dynamic event-triggered mechanism consensus algorithm in microgrid economic scheduling enhances system stability and reliability, significantly saves communication resources, and meets the economic requirements of microgrids, making it highly practical.
