Abstract
A multivariable regression MVR approach is proposed to identify the real power transfer between generators and loads Based on solved load flow results it first uses modified nodal equation method MNE to determine real power contribution from each generator to loads Then the results of MNE method and load flow information are utilized to determine suitable regression coefficients using MVR model to estimate the power transfer The 25bus equivalent system of south Malaysia is utilized as a test system to illustrate the effectiveness of the MVR output compared to that of the MNE method The error of the estimate of MVR method ranges from 0001 4 to 0007 9 Furthermore when compared to MNE method MVR method computes generator contribution to loads within 2640 ms whereas the MNE method takes 360 ms for the calculation of same real power transfer allocation Therefore MVR method is more suitable for real time power transfer allocation
