Global/Local Design Optimization of a Power Distribution System

摘要

The MATLAB/Simulink analysis tools developed and upgraded by the electrical engineering team were successfully incorporated into the optimization environment. A well posed optimization problem was formulated for a sample system consisting of a filter and converter. It was shown that the solution of the optimzation problem yielded realistic parameter values. Also the existence of suboptimal solutions was investigated. These results are the core results for developing an optimization methodology for the full power distribution system. The optimization methodology is being reworked into a global/local formulation. This formulation allows us to define an optimization problem for the entire power distribution system. A preliminary framework for the sample system has been developed, and the appropriate software is being generated. The global/ local formulation has also been applied to the design filters components with the inductors as their local level subcomponents. Preliminary results indicate a significant decrease in computational time while retaining the accuracy of the full problem.
