Distributed Economic Automatic Generation Control Algorithm for Multi Inverter AC Microgrid.

Assigning an agent to each inverter interface power supply in the Microgrid to complete communication and data calculation; designing the communication topology among the agents based on n−1 rule; identifying the Microgrid operation status in a distributed manner; initializing the algorithm based on the identified Microgrid operation state; and allocating an agent to complete the communication and data calculation for each inverter interface power supply in the Microgrid; Through the data interaction between agents, the generation reference value of each power source is distributed; the generation reference value is sent to the bottom droop controller to realize the distributed economic automatic generation control of Microgrid. The invention can combine the large time scale economic dispatch and the small time scale automatic generation control to form an economic automatic generation control, so that the multi inverter micro grid based on droop control can run economically in real time; and the algorithm can be implemented completely distributed and has strong robustness.
