| Summary: | 碩士 === 高苑科技大學 === 電子工程研究所 === 105 === In this paper, we propose an Ordinal Optimization (OO) algorithm for the solution of the Optimal Reactive Power Dispatch (ORPD) problem. The main objective of QRPD is to minimize active power loss and improve the voltage profile of power systems. Our algorithm consists of three stages. This work first constructed a crude but efficient model from a sample space. Then, a scheme with enhanced accuracy based on sensitivity theory was applied to identify the top samples to form the selected subset. Finally, we obtain a good enough solution with smallest objective value. The proposed algorithm is tested on IEEE 118-bus system and results are compared with those of tabu research method and genetic algorithms. Test results demonstrate the efficiency of proposed algorithm in finding the good enough solution within a shortest computing time.
