This paper introduces a new two-dimensional (2D) modeling approach for the fast calculation of inductor and transformer foil winding losses. The proposed modeling procedure is derived from the Partial Element Equivalent Circuit (PEEC) method, which is originally a full three-dimensional (3D) electromagnetic solution technique. With the presented modifications, the PEEC method can take into account...
Besides product differentiation, cost is a key parameter for market success and sustainable competitive advantage of industrial companies. Academic research in the field of power electronics, however, is often confined to the search for technical innovations or optimizations with focus on pure physical performance indices while the cost dimension is neglected. An explanation for the lack of such cost...
For utility-scale photovoltaic (PV) power plants, the trend goes towards larger installations with reduced levelized costs of electricity. Further cost reductions can be achieved by modular and redundant inverter topologies, which enable higher reliabilities and a better overall system availability. In this paper, a comparative evaluation of selected three-phase single-and multi-stage voltage source...
The main contribution of this paper is the development of a nonlinear control technique for the control of individual wind turbines in a wind farm. For this purpose, a control scheme based on feedback linearization and gain scheduled linear quadratic regulator (LQR) is applied to a horizontal axis, variable speed, pitch regulated wind turbine. As a result of the physical constraints of their components,...
