The electrical energy consumption continues growing and more applications relay on electricity. We can expect that more 60 % of all energy consumption will be converted and used as electricity. Therefore, it is a demand that production, distribution and use of electrical energy are done as efficient as possible. Further, the recent challenges with nuclear power plants are arguing to find more sustainable...
This paper studies the effectiveness of reactive power compensation using a multilevel, hexagram-converter-based STATic COMpensator (STATCOM) with one-cycle control (OCC) for a wind farm with fixed-speed turbines, and the interaction with the power system network. Comparison is made with several common types of multilevel voltage source converters used for STATCOM applications. A new voltage control...
This paper gives a review on the power electronic applications for wind energy conversion systems. Different types of wind energy conversion system (WECS) with different generators and power electronic converters are described, and different technical features are compared. The electrical topologies of WECS with different wind turbines are summarized and the possible uses of power electronic converters...
As wind power achieves higher penetration levels and becomes a more and more substantial portion of our electric energy supply, more stringent requirements are being placed on wind plants. As wind plants displace traditional synchronous generators in terms of percentages, the wind plants must also do their part to maintain stability and reliability of the power system. Modern power electronics are...
One important aspect of clean energy or green industrialization is the search for technologies (CTpsilas) that can reduce the major environmental impact of present energy sources. Alternative energy sources (AES) like micro-turbines, photovoltaic (PV), fuel cells, wave energy and wind turbines seem to meet the requirement for clean energy. Integrating these on-site generating sources into the larger...
The paper discusses a bidirectional DC/DC converter for interfacing an energy storage device in an autonomous power system, which consists of wind turbines and diesel generation units. The operation condition variations, such as switching load, could cause significant dynamics in an autonomous system. An energy storage device can effectively increase the utilization of the renewable energy and improve...
