Abstract :
According to characteristics of the micro sources and operating mode of a microgrid, the control methods of the micro sources applied in grid-connected mode and islanding mode are designed in this paper. The control of micro sources is realized conveniently and feasibly through electronic inverters. The constant power (P/Q) control strategy is utilized to realize that the active and reactive power of the micro sources can be controlled as constant values respectively. The voltage and frequency (V/f) control strategy could ensure the stability of voltage and frequency of microgrid operates in islanding mode. The corresponding controller is designed according to the methods, and the simulation results show the effectiveness of the proposed control strategy. The study on control strategies of micro source provides a platform for further studies of microgrid.
