Abstract This paper demonstrates the feasibility of using a new complementary controlling structure for decreasing the in-series-equipment power loss. While keeping the main duties of a grid-tied inverter, unbalanced three phase loads are compensated using this complementary current controller feature. A high-pass filter is employed on both direct and quadrature axes in the common Park reference frame for this compensation. Besides discussing the unbalanced loading effects on the key issues such as in-series-equipment power loss, total harmonic distortion, human safety along with active and reactive power transferring ripple, a new controlling scheme is thoroughly introduced. MATLAB/Simulink and Power Station environments are used for simulating the steady state and dynamic behavior of a practical radial 24-bus distributed network equipped with a PV plant. The simulation results verify the effectiveness of the proposed controlling method. According to the case studies, 587 KWh energy saving has achieved in a 30 kW radial distributed network.

分布式网络中具有新型功率损耗缓解功能的并网光伏逆变器的能量管理

摘要 本文论证了使用一种新的互补控制结构来降低串联设备功率损耗的可行性。在保持并网逆变器的主要职责的同时，不平衡的三相负载使用此互补电流控制器功能进行补偿。在公共 Park 参考系中的直轴和正交轴上均采用高通滤波器进行此补偿。除了讨论不平衡负载对串联设备功率损耗、总谐波失真、人身安全以及有功和无功功率传输纹波等关键问题的影响外，还深入介绍了一种新的控制方案。MATLAB/Simulink 和电站环境用于模拟配备光伏电站的实际径向 24 总线分布式网络的稳态和动态行为。仿真结果验证了所提出的控制方法的有效性。根据案例研究，在一个 30 千瓦的径向分布式网络中实现了 587 千瓦时的节能。
