Abstract :
This paper presents a generic trapezoid-type capability curve for any distributed generation technology. This curve is used to estimate the machine reactive power limits in terms of the actual active power and terminal voltage. The proposed simplification was tested on synchronous machines, doubly fed induction generators and full power converter interfaced generators. This methodology can be implemented in Volt/VAR control schemes when the estimation of DG capability is required.
