In order to improve the validity and accuracy of wind farm integrated power system dynamic analysis in high-altitude mountainous region, it is necessary to study on modeling of DFIG (Double-Fed Induction Generator) based wind farm considering non-uniformity of wind speed in mountainous region and its applicability analysis. Firstly, the wind speed characteristics of wind farm in high-altitude mountainous...
This paper presents an alternative method for estimating coherence of Inter-Area Oscillation(IAO) mode using Enhanced Empirical Mode Decomposition(E-EMD) technique and Correlation analysis(CA). It firstly extracts the components associated with the objective inter-area modes from each tie-line active power signal by utilizing the E-EMD techniques. Then the cross-correlation coefficients resulted from...
In order to enrich the acquisition means for the coherence index in the dynamic characteristics of inter-area oscillation(IAO), this paper proposed an integrated algorithm for tracking coherence of electromechanical oscillation using Masking Signal based Empirical Mode Decomposition (MS-EMD) and Correlation Analysis(CA). The case study has been carried out on a simplified system of Southeastern Australian...
This paper presents a novel approach for estimating mode shape for participation (MSFP) among areas or main power plants involving inter-area oscillation (IAO) mode, by analyzing power deviation (ΔP) signals. The case study has been carried out on a planning case in East China Power Grid (ECPG). The results indicate that the proposed algorithm is effective, and imply its potential applicability in...
