提出了一种基于高阶多输入多输出(MIMO)辨识的单相逆变器(SPIS-HERE并网)协调无功控制策略。所提出的单相逆变器控制策略包括一个监督控制，它封装了使用高阶乘法器交替方向法(ADMM)技术的本地逆变器控制器的无功参考的产生。该结构基于dq-Frame解耦的有功功率和无功功率控制。最主要的贡献是高阶辨识技术，它捕捉到配电网中无功潮流相对于关注点电压的灵敏度。结果在IEEE 123节点系统上进行了测试，结果表明，与低阶识别器相比，所提出的结构在电压控制方面具有更高的改善百分比。
A novel approach for coordinated reactive power control strategy for multiple Single Phase Inverters (SPIs-here grid connected) using a higher order Multiple Input Multiple Output (MIMO) identification is proposed in this paper. The proposed single phase inverter control strategy includes a supervisory control which encapsulates the generation of reactive power references for local inverter controllers using a higher order Alternating Direction Method of Multipliers (ADMM) technique. The architecture is based on dq-frame decoupled active and reactive power control for the SPIs. Main contribution is the high order identification technique that captures the sensitivity of the reactive power flow with respect to the voltage at the point of interest in the Distribution Network (DN). The results are tested on IEEE 123 bus system and it is observed that the proposed architecture shows higher percentage improvement in voltage control when compared to lower order identifiers.
