Reliability of Modern Power Electronic-based Power Systems

This paper introduces a systematic approach based on the V-shaped model-based reliability analysis for design and planning of power electronic-based power systems (PEPS). According to this concept, the system performance is analyzed employing the physics of failure mechanisms in each components of different units in PEPS. This will facilitate optimal and economic design of power converters as well as economic decision-making in planning of PEPS. Moreover, it helps to identify the weakest units and its components that can in turn help in reinforcement planning and spare unit optimization in PEPS. The viability of the proposed approach is illustrated on a DC distribution network and numerical analyses show how the proposed model-based reliability assessment approach can help to do optimal planning and design of future PEPS.
