碩士 === 國立臺灣海洋大學 === 電機工程學系 === 93 === Abstract Electric deregulation is a trend in the power industry, electric utilites will face more harsh market competition. How to lower costs for improving the performance of management and then to have surpluses to carry on the customer service with holding the market share will be the important issues. In addition, maintaining the market competition fairness is also one of important factors to successiful electrical industry liberalization. Therefore, whether ISO is with the best way of operations does affect the system security as well as the transmission company’s system extension plans for meeting the future system need. In addition, how did the supervisory control organization determine the existing system operation condition and the transmission tariff rationality, it also requires simulation tools to assist a reliable and economical system operation. This main purpose of this thesis is to propose a fast solution methodology of OPF based on linear programming. The integer control variables such as transformer tappings, and the number of capacitor/reactor banks will be decided by using the sensitivity factor and the fuzzy theory to avoid solving the integer programming problem and to accelerate the OPF solution speed. The objective function can be revised due to the system operation or the system planning.
