A New Energy Management Control of Modular Multilevel Converters for Coping with Voltage Stress on Sub-Modules

This paper investigates the impact of the operating condition on the SM voltage ripples. In particular, it is revealed that under the classical control scheme where the Modular Multilevel Converter internal energy varies naturally with the DC grid voltage, the traditional sizing approach based on the analytical expression of instantaneous SM voltage may fail to respect the SM voltage constraint. To tackle this problem, this paper presents a solution by incorporating the advantages of the explicit energy management and the developed analytical expressions of the SM voltage ripple, which achieves a better utilization of the converter asset.

PhD Loriane DESMARS “Study of electrical and thermal properties of epoxy-anhydride composite materials for high voltage insulation”

2019-04-04T11:12:50+00:00April 2nd, 2019|High Voltage Substation Equipment, HVDC Cable Systems, Phd|

The work presented in this manuscript has been motivated by the necessity to develop more efficient electrical insulating materials compared to commercially available ones. An epoxy-anhydride matrix filled with micron sized alumina, often used to produce GIS solid insulators, has been used as a reference for this study.
