Abstract: A control method for microgrid including multiple distributed generation and energy storage device are provided to perform the operation stable and efficient of the microgrid using the energy store device having the quick response characteristic. The energy storing device(61) of the quick response characteristic performs the first control. The distributed power(63) of the slow response characteristic performs the second control. In the second control, the distributed power outputs as the output of the energy store device by the first control. The control module(62) changes the output of the rest distributed power as the output of the energy storing device. The programmable locked loop performs the role of dividing the output of the whole energy storing device into each distributed power. The energy storing device controls microgrid. A plurality of distributed powers instead of the output of the energy store device makes the output value of the energy store device zero.
