A novel general distributed secondary control (DSC) scheme is proposed to implement coordination for both droop‐controlled and active power reactive (PQ)‐controlled generator (DG)‐clusters in multi‐microgrids (MMGs), using cluster concept. It not only reduces the steady‐state derivation caused by primary droop control, but also brings whole MMG into a new optimised operation state control. The implementation of DSC accomplished based on protocol combining pinning in‐group inter‐group...
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by loss of tolerance to self-antigen, autoantibody production, and abnormal immune response. Cuproptosis a recently reported cell death form correlated with the initiation development multiple diseases. This study intended probe cuproptosis-related molecular clusters in SLE constructed predictive model.We analyzed expression profile features genes (CRGs) based on GSE61635 GSE50772 datasets identified core module...
