| 摘 要： | 提出一种具有功率平滑功能的虚拟同步发电机控制策略。该策略不仅使并网逆变器能像同步发电机一样具备转动惯量以及参与调频调压等功能,而且还能起到平滑微电网功率波动的作用。给出了虚拟同步发电机指令电流生成算法、平滑功率指令算法以及二者相结合的方案,并给出了基于重复PI控制的指令电流跟踪控制方法,利用MATLAB /Simulink 对系统进行了仿真,验证了所提出控制策略的正确性。

| Abstract: | A novel control strategy for virtual synchronous generator combined with active power smoothing is proposed. This strategy not only enables grid-connected inverters to obtain moments of inertia,and the ability of participating in micro-grid frequency adjustment and voltage regulator, just like the synchronous generator, but also enables the inverters to smooth active power fluctuation of micro-grid. Virtual synchronous generator current generation algorithm, active power smoothing current generation algorithm, and the integration of the two algorithms is proposed. Meanwhile, the tracking control method of instruction current based on repetitive and PI control is given. System simulation is carried out on MATLAB / Simulink and simulation results verify the validity of the proposed control strategy. |
