  Vertically Integrated Power System around the world is being restructured into Horizontally Distributed Deregulated Power System. In the deregulated power system, the power transactions plays a major role. Effective management of power transactions decides the secure and economic operation of power system. As the real time operation and control of deregulated power system is mainly based on transactions, it would be better if the system studies are also based on the power transactions. This study analyses the technical feasibility of ATC estimation using real power transactions. This study proposes a Support Vector Machine (SVM) based method for ATC estimation using real power transactions as inputs. To the best of the knowledge this is the first attempt to use real power transactions as inputs for ATC estimation using SVM. The proposed methods are tested on IEEE 24 bus Reliability Test System (RTS) and IEEE 118-bus System. The results are compared with Repeated Power Flow (RPF) results and the results of SVM Model developed using real power loads as inputs.

  This study describes the development and validation of dissolution tests for sustained release Dextromethorphan hydrobromide tablets using an HPLC method. Chromatographic separation was achieved on a C18 column utilizing 0.5% triethylamine (pH 7.5) and acetonitrile in the ratio of 50:50. The detection wavelength was 280 nm. The method was validated and response was found to be linear in the drug concentration range of 10-80 μg mL-1. The suitable conditions were clearly decided after testing sink conditions, dissolution medium and agitation intensity. The most excellent dissolution conditions tested, for the Dextromethorphan hydrobromide was applied to appraise the dissolution profiles. The method was validated and response was found to be linear in the drug concentration range of 10-80 μg mL-1. The method was established to have sufficient intermediate precision as similar separation was achieved on another instrument handled by different operators. Mean Recovery was 101.82%. Intra precisions for three different concentrations were 1.23, 1.10 0.72 and 1.57, 1.69, 0.95 and inter run precisions were % RSD 0.83, 1.36 and 1.57%, respectively. The method was successfully applied for dissolution study of the developed Dextromethorphan hydrobromide tablets.
