...1) Conventional distributed control based on droop characteristics Under the well-known d-q (direct-quadrature) reference frame, the large-signal nonlinear dynamical model of microgrids with voltage source converters [119], [120] can be described in a compact form { ẋi = fi(xi) + gi(xi)ui + hi(xi)Di y(1) i = vodi, y 2 i = wi = −d p iPi + u2,i (8)...
