One of the main drawbacks of the existing oscillation damping controllers that are designed based on offline dynamic models is adaptivity to the power system operating condition. With the increasing availability of wide-area measurements and the rapid development of system identification techniques, it is possible to identify a measurement-based transfer function model online that can be used to tune...
In the first part of this paper, the methodologies of earth resistivity measurement and estimation have been studied. The horizontal layered soil (HLS) model obtained by the first part of this paper is usually with over 10 layers, which is far more than the existing HLSs used for grounding design. The parameters of the HLS of wide areas are also irregular, which means the resistivity or thickness...
The paper presents two groups of measurement based multi-inputs, multi-outputs (MIMO) system identification approaches, which are subspace state-space identification and transfer function identification. The purpose is to compare the performance and features of these methods in terms of electromechanical oscillation damping estimation. The selected methods are validated by using ambient data and ring-down...
One of the main drawbacks of the existing wide-area damping controller (WADC) that are usually tuned based on several selected typical operating conditions, is its limited adaptability to continuous variations in operating conditions. An adaptive WADC employing the lead-lag structure using measurement-driven model is proposed in this paper. The state subspace model is identified online using ambient...
