Power optimal decentralized coordinated control method of microgrid

Microgrid contains a variety of micro sources in scattered locations and its transmission line impedance parameters exist particularity. These factors led to the unreasonable distribution of micro sources supply. How to coordinate the control of micro sources and achieve safe, high efficient and stable operation is a serious problem. Based on P-f/Q-V droop control method, this paper binding partially decentralized coordinated control method proposes the method to solve reactive power allocation problem between a variety of micro sources in parallel operation. In consideration of microgrid particularity, the proposed coordinated control method achieve a reasonable power distribution between the micro sources. Finally, the simulation results verify the correctness and feasibility of the proposed coordinated control method.
