Abstract
This paper presents a wind turbine generator (WTG) reduced-order model for time domain simulations. Selective modal analysis is used to reduce the model order by focusing on the most relevant modes and variables. In most cases, a single relevant mode is found; thus, a first-order model that captures the relevant mode is derived. Depending on the WTG dynamics, in some cases, reduced-order models of higher order are required. The proposed model is applied to both 4-bus and 39-bus test systems. The results show that the proposed reduced-order model closely resembles the impact of WTGs in a power system, even when large perturbations occur. Line and synchronous generator (SG) outages are taken into account. The proposed model reduces the simulation time and the power system model complexity.
