N2 - In this paper, a multi-channel system identification (SI) based adaptive wide-area damping controller (WADC) is proposed for a distributed energy resources (DER) integrated power grid. The proposed design identifies the multiple-input multiple-output (MIMO) reduced order transfer function model of the system using recursive least square (RLS) algorithm and utilizes adaptive control framework to adjust the power output of DER based upon the identified model to improve the transient stability of the system. The concept is to utilize the proposed controller to augment converter based local control of DER to damp the system oscillations faster. The benefit of the proposed control methodology has been validated by conducting simulation studies on a modified two area system to damp the inter-area oscillations. The results demonstrate that through coordinated control of different DERs, oscillations can be damped faster compared to using only local power system stabilizers (PSS) and conventional wide area damping controllers (WADC).
