Prediction of Instability Points Using System Identification

چکیده
Determining maximum loading margins is an important issue in power system operation, as system operators must take proper preventive actions to avoid stability problem. In this paper, an index based on the identification of critical modes of the system is presented. The proposed index does not need a system model as it is based on actual field measurements. Compared to other existent indices, the proposed index yields more accurate stability margins as if accounts for the full dynamic response of the system, at lower computational costs, which would make it an adequate tool for on-line stability monitoring.

Prediction of transient instability and unplanned islanding using phasor measurements data
in this paper a new algorithm has been proposed to predict unplanned islanding. To predict unplanned islanding, rotor angle and speed time series have been used. Times of fault occurrence and clearance are estimated using monitoring system response based on the variation of phasor measure data. The estimated times of fault occurrence and clearance are used to determine suitable calculation wind...

The classification and regression trees (CART) possess the advantage of being able to handlelarge data sets and yield readily interpretable models. In spite to these advantages, they are alsorecognized as highly unstable classifiers with respect to minor perturbations in the training data.In the other words methods present high variance. Fuzzy logic brings in an improvement in theseaspects due ...

متن کاملIdentification of Multiple Input-multiple Output Non-linear System Cement Rotary Kiln using Stochastic Gradient-based Rough-neural Network
Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties. Cement rotary kiln (CRK) is a MIMO nonlinear system in the cement factory with a complicated mechanism and uncertain disturbances. The identification of CRK is very important for different pur...
