Abstract
This paper presents three types of linear model
order reduction (MOR) technique, namely singular value de-
composition (SVD)-based, Krylov-based, and modal truncation-
based type applied to large-scale wind farm models. The first
type includes a Balanced Truncation (BT) and Alternating
Direction Implicit (ADI)-based BT method, while the second
type encompasses a Rational Krylov (RK), and Iterative Rational
Krylov Algorithm (IRKA) method. In the third type, a Subspace
Accelerated MIMO Dominant Pole Algorithm (SAMDP) method
is used. The effectiveness of these methods are tested on practical-
sized wind farms with 90, 120 and 210 doubly-fed induction
generators (DFIGs). Merits and demerits of each method are
discussed in detail. The reduced order model (ROM) of wind
farm is validated against the full order model (FOM) in term of
frequency domain indices and waveform agreement at the point
of common coupling (PCC).
