Abstract

The cascaded H-bridge multi-level converter is the main topology of high-voltage and high-capacity converter in renewable energy power generation, energy storage system and reactive power compensation equipment. The parameter design of cascaded H-bridge multi-level converters directly determines the material cost and performance. Taking the output current distortion rate and the ripple voltage of the capacitor of the cascaded H-bridge multi-level converter as the constraint conditions, this paper proposes an overall parameter optimal design method of the cascaded H-bridge multi-level converter based on the optimization of the total material cost. Finally, the effectiveness of the proposed parameter design method is verified by the simulation result.

风电场中级联 H 桥多电平转换器的优化参数设计方法

级联 H 桥多电平变流器是可再生能源发电、储能系统和无功补偿设备中高压大容量变流器的主要拓扑结构。级联 H 桥多电平变换器的参数设计直接决定了材料成本和性能。本文以级联 H 桥多电平变换器的输出电流畸变率和电容器纹波电压为约束条件，提出了一种基于材料总成本优化的级联 H 桥多电平变换器整体参数优化设计方法。最后，通过仿真结果验证了所提参数设计方法的有效性。

期刊介绍： IET Renewable Power Generation (RPG) brings together the topics of renewable energy technology, power generation and systems integration, with techno-economic issues. All renewable energy generation technologies are within the scope of the journal. Specific technology areas covered by the journal include: Wind power technology and systems Photovoltaics Solar thermal power generation Geothermal energy Fuel cells Wave power Marine current energy Biomass conversion and power generation What differentiates RPG from technology specific journals is a concern with power generation and how the characteristics of the different renewable sources affect electrical power conversion, including power electronic design, integration in to power systems, and techno-economic issues. Other technologies that have a direct role in sustainable power generation such as fuel cells and energy storage are also covered, as are system control approaches such as demand side management, which facilitate the integration of renewable sources into power systems, both large and small. The journal provides a forum for the presentation of new research, development and applications of renewable power generation. Demonstrations and experimentally based research are particularly valued, and modelling studies should as far as possible be validated so as to give confidence that the models are representative of real-world behavior. Research that explores issues where the characteristics of the renewable energy source and their control impact on the power conversion is welcome. Papers covering the wider areas of power system control and operation, including scheduling and protection that are central to the challenge of renewable power integration are particularly encouraged. The journal is technology focused covering design, demonstration, modelling and analysis, but papers covering techno-economic issues are also of interest. Papers presenting new modelling and theory are welcome but this must be relevant to real power systems and power generation. Most papers are expected to include significant novelty of approach or application that has general applicability, and where appropriate include experimental results. Critical reviews of relevant topics are also invited and these would be expected to be comprehensive and fully referenced. Current Special Issue.
