Development of power electronic devices requires multi -disciplined engineering activities. These cover the thermal, electrical and software design. Due to this design complexity rapid prototyping methods and model-based design are becoming more and more important in the R&D projects in this field. In case of the multi-level inverter based drives the strict reliability requirements make the aforementioned new approaches more attractive. This article is the first part of the series which introduces the application of the model based design and Hardware-in-the-Loop (HIL) tools through the modeling of a Cellular H-Bridge inverter (CHB). This article focuses on the power electronic system modeling and verification. The model of the CHB is implemented and verified in Matlab.

In order to adapt to the current multi-level dispatching management system and to promote the operational efficiency of interconnected electricity networks, this paper proposes a decomposition collaborative model based on optimal power flow theory. The model is a quadratic programming question used to solve optimal power flow model. The information of interchanging between regions is communication price and boundary nodal bus phase angle. IEEE 30-bus test system demonstrates the validity and novelty of the model that the regional network can be calculated reasonably and the development of cross-regional electricity transaction is promoted effectively.
