直流微电网采用下垂控制策略时,下垂系数过大或过小都会对系统局部稳定性和阻尼比造成影响。为此,文中提出一种基于摄动理论的下垂系数优化方法。首先,综合考虑小扰动稳定、阻尼比和稳定裕度等因素,建立下垂系数优化目标函数。然后,通过对下垂系数进行矩阵摄动分析,将求取的特征值增量应用于算法迭代过程,避免了优化过程中特征值反复求解以及矩阵反复形成的问题。最后,通过仿真模型和物理实验进行了验证,仿真和实验结果表明,该方法能够有效提升直流微电网的稳定性及稳定裕度。
When the droop control strategy is used for the DC microgrid
too large or too small droop coefficient will affect the local stability and damping ratio of the system. Therefore
this paper proposes an optimization method of droop coefficient based on perturbation theory. Firstly
considering the factors such as small disturbance stability
damping ratio
and stability margin
the optimization objective function of the droop coefficient is established. Then
through the matrix perturbation analysis of the droop coefficient
the eigenvalue increment is applied to the iterative process of the algorithm. It avoids the problems of repeated solutions of eigenvalues and repeated formation of the matrix in the optimization process. Finally
the simulation and experiment results show that the proposed method can effectively improve the stability and stability margin of the DC microgrid by the verification of simulation model and physical experiment.
