Abstract
- Summary: This paper analyzes the equivalent impedance characteristics of the ac microgrid with distributed renewable energy generations (DRGs) based on the droop control and proposes a decoupled power flow calculation method. The droop control strategy with adaptive virtual impedance has become an effective solution to utilize the DRG. To analyze the characteristics of the DRG, a microgrid consisting of multi‐DRGs based on distributed consensus‐based secondary voltage droop control with adaptive virtual impedance is researched. Considering the characteristics of the DRGs, a decoupled power flow calculation can be proposed to satisfy the quick power flow calculation in order to achieve economic dispatch and stability recovery for the microgrid. Furthermore, the accuracy of the power flow calculation with considering virtual impedance is improved. Moreover, a small microgrid, including three DRGs, has been modeled and simulated using the MATLAB/Simulink. Eventually, the decoupled power flow calculation is tested on three test case systems.
