Medientyp: E-Artikel Titel: Wind power and hydrogen generation system with cooperatively controlled three‐level NPC‐VSC based energy capacitor Beteiligte: Muyeen, S. M.; Takahashi, R.; Tamura, J. Erschienen: Wiley, 2010 Erschienen in: European Transactions on Electrical Power Sprache: Englisch DOI: 10.1002/etep.385 ISSN: 1430-144X; 1546-3109 Schlagwörter: Electrical and Electronic Engineering ; Energy Engineering and Power Technology Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>One of the recent challenges for transmission system operators (TSO) or power grid companies is to smoothen the output power fluctuation of wind generator due to the random variation of wind speed. In addition to the output power fluctuation of fixed‐speed wind turbine generator system (WTGS), it suffers greatly from terminal voltage fluctuation. The fixed capacitor bank connected to its terminal cannot maintain constant terminal voltage under randomly varying wind speed. On the other hand, besides the continuous growth of wind power, hydrogen generation system is also becoming very popular nowadays using the electrical energy from wind power plants. This study proposes a three‐level neutral point clamped voltage source converter (NPC‐VSC) based energy capacitor system (ECS), composed of electric double layer capacitor (EDLC) and power electronic converters, to smoothen output power and terminal voltage fluctuations of grid connected fixed speed wind farm. A simple low pass filter (LPF) is adopted in this study to generate the power reference of ECS. Another salient feature of this study is the generation of hydrogen by using wind generator output power. Effective topology of wind power and hydrogen generation system with cooperatively controlled NPC‐VSC based ECS is proposed from the cost and performance points of view.
