摘要

为实现含高比例可再生能源情形下直流微电网母线电压的平稳控制，提出基于微分平滑理论的多直流电力弹簧(DCES)协调控制方法。针对直流微电网多DCES非线性特性与多运行工况，上层设计微分平滑控制方法，直接补偿非线性分量，确保在可再生能源出力波动、系统参数摄动情形下直流母线电压平稳，提升系统稳定性与鲁棒性，同时为下层控制提供电感电流参考轨迹；下层控制设计基于DCES工作模态的模型预测控制方法，通过简化寻优计算量，确保系统动态响应的快速性，无需通信，即可实现电感电流参考轨迹跟踪与各段直流母线电压波动平抑。基于MATLAB/Simulink的仿真结果和基于dSPACE的实验结果验证了所提方法的正确性和可行性。

Abstract

In order to realize voltage smoothing control of the DC microgrid with high proportion of renewable energy

this paper proposes a coordinated control method of multiple DC electric springs (DCESs) based on differential flatness theory. Considering the nonlinear characteristics and multiple working modes of multiple DCESs in the DC microgrid

the differential flatness control method is designed for the upper layer to directly compensate nonlinear components

which ensures stable DC bus voltage under the condition of renewable energy output fluctuation and system parameter perturbation. The stability and robustness of the system are improved

and the reference trajectories of inductor currents are provided for the lower layer. The model predictive control (MPC) method based on the working modes of DCESs is designed for the lower layer. By simplifying the optimization calculation

the rapid dynamic response of the system can be ensured

and the tracking of reference trajectory of inductor current and the voltage fluctuations of various DC bus segments can be achieved without communication. The simulation results based on MATLAB/Simulink and the experimental results based on dSPACE show the correctness and feasibility of the proposed method.
