Optimized Operating Points for Power Electronic Building Blocks

Systems that place high demands on availability are typically modular in design. However, a modular design also offers potential for optimized operation under norma requirements. In this paper we present an approach to find optimal operating points from the characteristic fields of individual modules. Our approach consists of a two-step procedure. In the first stage, Pareto sets are calculated using the NSGA-II genetic algorithm. The second stage contains a heuristic that finds situationally optimal operating points using a defined operating strategy.
