碩士 === 國立臺灣科技大學 === 電機工程系 === 91 === Abstract The voltage/reactive power control problem in electrical system is an important issue of utility system operation and management. There are many research papers on the optimal exploration of voltage/reactive power control problem to keep the bus voltage violation within the allowable deviation zone of standard voltage and to minimize the line losses. This dissertation presents a approach to reduce the electrical network into a simple proposed model applying radial equivalent independent method ( REI method ). Based on reduced equivalent model, a feasible solution for scheduling standard voltage and transformer tap/var control using genetic algorithm is developed. The objective of this proposed solution is properly to monitor the load-center bus and substation buses keeping the voltage violation within the deviation zone of expectation values and to minimize the necessary control operation frequency of the transformer tap changer and reactive power regulating equipment. Although the major contributions of this dissertation is intended for application in the system voltage operation and supervision control, it would also be useful in planning studies. Simulation results supporting the validity of the proposed solution in Taipower substations are presented.
