    摘要:

    本文针对一类控制通讯信道受到攻击下直流微电网系统母线电压波动问题, 提出一种基于滑模控制方法的镇定策略, 以实现动态控制与快速响应. 首先, 在直流微电网系统中引入蓄电池储能系统并构建系统数学模型. 然后, 设计积分滑模控制策略, 来控制储能系统注入镇定电流以稳定直流母线电压, 从而抑制非线性扰动和虚假数据注入攻击对系统性能的影响. 同时, 借助适当的 Lyapunov 泛函, 得到确保滑动模态渐近稳定和滑模面可达性的充分条件, 保证直流微电网系统能够实现对负载需求的迅速响应及稳定运行. 最后, 通过 Matlab 数值仿真验证本文所提出的滑模控制策略的有效性.

    Abstract:

    In this paper, a stabilization strategy based on sliding mode control method is proposed to solve the problem of bus voltage fluctuation in DC microgrid system under attack of control communication channel. Firstly, the battery energy storage system is introduced into the DC microgrid and the mathematical model of the system is constructed. Then, an integral sliding mode control strategy is designed to control the energy storage system to inject stabilizing current to stabilize the DC bus voltage, so as to suppress the influence of nonlinear disturbance and false data injection attack on the system performance. By an appropriate Lyapunov functional, sufficient conditions are obtained to ensure the asymptotic stability of sliding mode dynamics and the reachability of sliding surface, so that the DC microgrid system can realize the rapid response to load demand and stable operation. Finally, the effectiveness of the proposed sliding mode control strategy is verified by MATLAB numerical simulation.
