To realize the effective control of power quality (PQ) in microgrid cluster (MGC) by means of PQ assessment of MGC and the cooperation with multiple converters, a novel strategy for MGC based on ultra-short-term PQ assessment is proposed. First, an ultra-short-term PQ assessment method is employed to evaluate and locate the PQ problems in MGC in real time. Then, according to the positioning results, a distributed consensus algorithm is utilized to coordinate the control of multiple converters, thus achieving the PQ task allocation and governance. After the completion of governance, the assessment and verification are performed again to ensure the governance effect and further form a closed-loop governance system at the level of MGC. Finally, the results of an example show that compared with the traditional method, the proposed strategy can realize the closed-loop control of PQ problems from the perspectives of identification, assessment and governance at the level of MGC while effectively reducing the harmonic distortion rate, thereby realizing the effective assessment and governance of PQ in MGC.
