摘要
在建立MMC-BESS数学模型的基础上,实现了直流侧三相解耦的功率控制策略和交流侧同步旋转坐标系下有功和无功的解耦控制策略。实验验证功率控制策略稳态下系统控制模型的准确性,暂态下系统控制模型的快速响应能力;交流侧有功无功的典型工况实验验证了系统交流侧功率解耦控制的能力。实验结果验证了MMC-BESS数学模型和功率控制策略的正确性。
Based on the mathematical model of MMC-BESS,the power control strategy of DC side three-phase decoupling and the decoupling control strategy of active and reactive power in AC side synchronous rotating coordinate system are realized.The experiments verify the accuracy of the system control model under steady state and the fast response ability of the system control model under transient conditions.The typical working condition test of active and reactive power on the AC side verifies the ability of power decoupling control on the AC side of the system.The experimental results verify the correctness of the MMC-BESS mathematical model and power control strategy.
