Abstract
To help mitigate some of the challenges associated with the wide spread adoption of the stochastic wind power, wind turbine with full-scale power converter (Type D) is preferred. Since full power is processed by the power converter in a type D wind turbine, it is important to improve its efficiency and reduce the cost per kW to achieve lower cost of energy. The power produced by the wind turbine varies in a wide range and the conventional design approach of optimizing converter at a specific loading condition may be sub-optimal. To overcome this challenge, a mission-profile based multi-objective optimization approach for designing power converter is presented. The objective is to minimize the energy loss for a given load profile as against the conventional approach of minimizing power loss at specific loading conditions. The proposed approach is illustrated by designing a grid-side power converter for 2 MW, 690 V wind turbine. The loss and volume models of the semiconductor and passive components have been discussed and design procedure has been demonstrated.
