摘要

This paper was interested in flexible control of an active generator (AG) that includes a wind turbine, battery-supercapacitors hybrid storage system, and loads. This AG can operate according to grid stability in islanded, synchronization, and grid-connected modes. The developed control strategy comprises two principal control tasks: the first one is a two-layer power management algorithm (PMA). The response of two-layer PMA enables to detect the islanding mode in case of grid fault and to monitor the renewable power generation into nine operating modes according to the state-of-charge of each storage system. The second task is droop control. This droop control aims to reduce grid voltage and frequency variations. It controls exchanged powers with grid to ensure its stability. It also ensures a continuous supply of load in case of grid fault. The system is simulated using MATLAB software, and results are provided in order to show the feasibility of this control strategy.
