| Summary: | 碩士 === 建國科技大學 === 電機工程系暨研究所 === 97 === In this thesis, three loss formulas based on Jacobian Based Distribution Factor (JBDF) have been proposed. Different from the conventional ones that expressed by network parameters, the proposed loss formulas approach the transmission losses by real and reactive power line flows without any assumptions. The line flows can be formulated by JBDF sensitivity factors. These new formulas have also been involved in the computations of economic dispatch. Different loading conditions are included in the computations to test their performance. Finally, two sample systems, IEEE 14-Bus system and IEEE 30-Bus system, are used to test the accuracy and goodness of the proposed methods. As demonstrated by the numerical results, it appears that the proposed methods have good accuracy for the computations of transmission loss and economic dispatch problem. Even though needn’t any assumptions, they remain good accuracy when load demands change from base case in either conforming or nonconforming conditions. As a summary, the proposed three loss formulas are very accurate and suitable for real time applications.
