报告摘要：
The continuously increasing demand for electric power and the need for efficient grid integration and transmission of remote large-scale renewable energy resources have revived the interest in High-Voltage Direct Current (HVDC) systems. The HVDC systems based on the Voltage-Sourced Converter (VSC) are a promising technology for (i) expansion of the power networks for large cities, (ii) grid integration of renewable energy resources, i.e., hydropower and offshore wind farms, (iii) long-distance bulk power transmission, (iv) interconnection of asynchronous power grids, and (v) electrification of isolated loads, islands, and oil and gas stations.
The key enabling technology for VSC-HVDC systems is efficient, scalable, and fault-tolerant high-power VSCs. The Modular Multilevel Converter (MMC) topology is a newly introduced VSC which, conceptually, does not have the drawbacks of the existing high-power VSCs. The emergence of the MMC has opened up a new avenue for research and development of not only the VSC-HVDC systems but also for other emerging applications including interfacing energy storage devices to the utility grid, collection systems of offshore wind farms, and medium-voltage high-power adjustable speed drives.
The first part of this presentation provides an overview of the MMC-HVDC systems and current research challenges that need to be addressed. In the second part of this presentation, other emerging application spaces of the MMCs along with their technical challenges/issues are introduced and discussed. The speaker’s research activities on addressing those challenges will be presented.
