摘要：
The power quality of an AC bus deteriorates because of various non-linear loads entering the hybrid micro-grid, at the same time as the bidirectional flow of electric energy is required in the AC and DC bus. In this paper, a virtual APF topology and its control strategy are proposed. A constant power control system is designed using instantaneous power theory. According to the power requirements of the AC / DC hybrid power system, the virtual APF is controlled to work flexibly in three working modes i.e. active power filtering, rectifier and grid-connected inverter. Looking at realizing the bidirectional flow of between DC micro-grid and power system, the harmonics in the AC / DC hybrid micro-grid system are treated. This improves the utilization rate of the interface converter and reduces the operating cost of the system. The correctness and feasibility of the proposed virtual APF topology and its control strategy are verified by simulation. © 2020, Power System Protection and Control Press. All right reserved.
