摘要
研究综合能源系统的协同能源管理问题,并提出了一种基于异步动态事件触发通信策略的分布式梯度算法来解决该问题.通过引入外部辅助变量并设计有效的触发机制,该方法可以使得每个参与者仅在必要时刻以离散且异步的方式与邻居产生通信交互,实现了连续通信的离散替代化.同时,该方法并不要求全局同步时钟,具有更强的灵活性.此外,本文也在理论上证明了算法的全局收敛性.最后,仿真结果验证了所提方法的有效性.
This paper investigates the collaborative energy management problem for integrated energy system,where an asynchronous and dynamic event-triggering communication strategy based distributed gradient algorithm is proposed to solve this problem.By introducing external auxiliary variable and designing effective triggering mechanism,this method can enable each participant sharing information with neighbors in a discrete and asynchronous communication fashion if only necessary.In this way,the continuous algorithm can be implemented in a discrete communication fashion.Meanwhile,this method does not rely on global clock synchronization,resulting in enhanced flexibility.In addition,the global convergence of the proposed algorithm is also proved in theory.Finally,the simulation results show the effectiveness of the proposed method.
