Energy correction procedure on cross-border energy exchange using a virtual measuring point

Measurement procedures in cross-border energy exchanges usually neglect the associated measurement uncertainties, which is likely to result in financial damage to one, or both, transmission system operators. In this paper, measurement uncertainty analysis at the measurement point is extensively described and a correction procedure for its systematic contributions is presented. Aiming to develop a fair procedure for the exchanged energy distribution among transmission system operators, the concept of the virtual measuring point is introduced, taking into consideration measurement uncertainties and generated transmission losses. After performing the correction procedure, the virtual measuring point is converted into the corrected virtual measuring point, whose energy measurement is used for the final billing procedure. The presented method was tested in a practical example with data from a Croatian transmission system operator Ltd. and it was confirmed that the correction procedure can be of great interest for transmission system operators.
