摘要

在双高电力系统的场景下，跟网型逆变器需要利用锁相环PLL（phase-locked loop）精准提取电网电压相位，在复杂工况下可能会出现跟踪滞后与相位偏差较大的问题。同时，基于比例积分PI（proportional integral）的传统并网控制策略需涉及烦琐的参数整定工作，不仅增加了控制器的设计难度，还难以适应不同电网强度的变化。为此，基于模型预测控制MPC（model predictive control）的非线性目标约束处理能力与快速动态响应特性，提出跟网型逆变器全MPC策略。首先，建立离散控制集下的MPC-PLL结构，精准提取电网电压相位；其次，采用连续控制集模型预测控制CCS-MPC（continuous control set-model predictive control）构建MPC电流环，通过控制计算可直接输出最优开关状态；最后，构建以直流侧电压稳定为控制目标的MPC电压环，提供可靠的直流侧支撑并生成最优电流参考指令。仿真与实验结果表明，在强弱电网不同工况下，建立的全MPC控制策略的暂稳态性能均优于传统PI。该结果将为跟网型逆变器控制技术发展提供全新参考，为大规模可再生能源并网逆变器的稳定运行提供理论支撑。

Under the scenario of a power system with high proportion of renewable energy integration and high power electronic penetration (i.e., a “double-high” power system), grid-following inverters rely on phase-locked loop (PLL) to accurately extract the phase of grid voltage. However, problems such as tracking lag and large phase deviation may occur under complex operating conditions. Meanwhile, the traditional grid-connected control strategy based on proportional-integral (PI) regulators involves tedious parameter tuning, which increases the design difficulty of the controller and makes it difficult to adapt to variations in different grid strengths. To address these issues, a full model predictive control (MPC) strategy for grid-following inverters is proposed by leveraging the nonlinear objective constraint handling capability and fast dynamic response characteristics of MPC. First, an MPC-PLL structure under a discrete control set is established to accurately extract the grid voltage phase. Second, continuous control set-model predictive control (CCS-MPC) is adopted to construct an MPC current loop, which can directly output the optimal switching states through control calculations. Finally, an MPC voltage loop with the control objective of DC-side voltage stabilization is built to provide reliable DC-side support and generate the optimal current reference commands. Simulation and experimental results demonstrate that the proposed full MPC strategy outperforms the traditional PI-based strategy in both the transient and steady-state performance under different operating conditions of weak and strong grids. These results provide a novel reference for the development of control technologies for grid-following inverters and offer theoretical support for the stable operation of large-scale renewable energy grid-connected inverters.
