The Effect of the Accuracy of Reactive Power Measurement on Transmission Node Cost

Abstract:

Power flow calculation is the fundamental of cost analysis of transmission node. In traditional methods, the rationality of the cost analysis is of more concern than the accuracy of the power flow calculation’s results. This paper starts from the reactive data that being used for power flow calculation, expatiate that the method of present reactive power data measurement is inaccurate and explains why it is inaccurate. What reactive power would do to node cost analysis and why it could do so are analyzed considering cost analysis of transmission node. At last, an example of IEEE 9 is used. And it is proved that the fluctuation of reactive power will affect the power distribution of the whole network, as a result affect the generators’ sale of electricity income to loads greatly.
