Distributed reactive power control strategy based on adaptive virtual reactance

In high‐voltage microgrid, the line impedance is mainly inductive and the reactive power of the load cannot be shared equally and reasonably due to the transmission line impedance mismatches. This paper proposes a distributed reactive power control strategy combined with an adaptive virtual reactance method. The proposed control strategy does not require line impedances estimation or a central controller; each DG only needs information from its neighbours to achieve control of the reactive power, which can reduce communication costs and improve system reliability. An adaptive compensator is employed to reduce voltage deviations. Finally, MATLAB/Simulink simulation and hardware‐in‐the‐loop experiment are conducted to verify the effectiveness of the proposed control strategy.
