微电网中分布式电源的增加以及敏感负荷的投入,导致仅靠具有渐进收敛特性的传统分布式二次调频策略难以保证系统的动态性能,而常用的有限时间调频策略的收敛上界在不同程度上受到系统初始状态、系统参数等因素的制约。针对这一问题,基于分布式控制原理提出并设计了一种具有时变增益的分布式有限时间调频策略。首先,介绍了传统分布式二次调频策略的工作机理,并利用李雅普诺夫稳定性理论分析了常用有限时间调频策略的局限性。然后,在传统分布式调频策略的基础上,根据其渐进收敛特性将其常数增益改进为具有周期加速收敛特性的时变函数,提出并设计了一种以时变函数为增益的分布式有限时间调频策略,解决了收敛时间受系统初始状态、系统参数制约的问题。最后,通过理论及仿真验证了所提方法在加速频率收敛、提高系统灵活性方面的有效性及优越性。
The increase of distributed generators and the input of sensitive loads in microgrids have made it difficult to guarantee the system dynamic performance by relying solely on traditional distributed secondary frequency regulation strategy with progressive convergence characteristics
while the convergence upper bound of commonly used finite-time frequency regulation strategy is limited by system initial state and system parameters to varying degrees. To solve this problem
a distributed finite-time frequency regulation strategy with time-varying gain is proposed and designed based on the distributed control principle. First
the working mechanism of the traditional distributed secondary frequency regulation strategy is introduced
and the limitations of commonly used finite-time frequency regulation strategy are analyzed by using Lyapunov stability theory. Then
on the basis of traditional distributed frequency regulation strategy
the constant gain is improved to a time-varying function with periodic acceleration convergence characteristics according to its progressive convergence characteristics. And a distributed finite-time frequency regulation strategy with time-varying gain is proposed and designed
which solves the problem that the convergence time is limited by system initial state and system parameters. Finally
the effectiveness and superiority of the proposed method in accelerating frequency convergence and improving system flexibility are verified through the theory and simulation.
