Stability analysis of grid-connected hydropower plant considering turbine nonlinearity and parameter-varying penstock model

Abstract This paper aims to investigate the nonlinear stability and dynamic characteristics of the grid-connected hydro-turbine governing system (GCHTGS) considering the parameter-varying model (PVM) of penstock and turbine nonlinearity. Considering the inertia of fluid flow and water head loss of t...
