多台具有谐波补偿功能微源逆变器的协调控制

摘要

研究了微电网中多台具有谐波补偿功能的微源逆变器之间的协调控制。给出了交流微电网的结构以及具有谐波补偿功能微源逆变器的拓扑。通过将并网供电参考电流和谐波补偿参考电流叠加的方法得到微源逆变器的参考电流。研究了各微源逆变器在完成自身并网供电的前提下，根据其剩余容量按比例对谐波补偿的协调控制策略。采用Matlab／Simulink验证该文所研究的协调控制策略的正确性和有效性。%Coordination control of multiple micro-source inverters with harmonic compensation is studied in this paper .The structure of the micro-grid and the topology of micro-source inverter are shown . The reference current of micro-source inverter can be objected by adding the grid-power reference current and harmonic compensation reference current .On the basis of each micro-source inverter transmission power to micro-grid, the coordination controls strategy of harmonic compensation is proposed according to the excess capacity of micro-source inverter .The coordination controls is proved to be correct and effec-tive by Matlab/Simulink.
