Wind energizer from Leviathan Energy Boosted the output of wind turbines with 30% by Breakthrough Design

Leviathan Energy has completed initial testing on their Wind Energizer unit and is reporting gains in wind turbine output in the range of 15 to 30% — and as much as 150% at lower wind speeds.

The theory behind this work is that by placing passive objects around a wind turbine ( wind farm according to http://cleantechnica.com/2009/04/29/wind-turbine-output-boosted-30-by-breakthrough-design) it will change the circulation around the wind turbine. The advancement is not in the turbine itself, but rather in the area around it, as such, units can be adapted to any wind turbine from any manufacturer.

I found it useful for a first start in understanding how wind turbines work and which are the main components of a WT.

Benchmark test systems in IEEE and PSS/E formats

We all know that for validating research studies in power engineering benchmark standardized systems might be used. Therefore, my intention on this blog was to provide web links to such Test (benchmark) Power Systems in IEEE and PSS/E formats for both load flow, power economics and signal dynamics analysis. Currently there is an ongoing project of the IEEE Task Force on Test Systems for Economic Analysis (IEEE-TEA), which has as aim to derive benchmark test systems specifically for energy economic studies. In this respect the group created a wiki web site where they intend to post those specific benchmark test systems: http://www.ieee-tea.ethz.ch/wiki 

However, the most cited link for benchmark test systems in IEEE Common Data Format/PTI Power Flow Data Format /PECO PSAP Format is the following:

http://www.ee.washington.edu/research/pstca/.

The above cited site is maintained by dr. Richard D. Christie, Associate Professor at the University of Washington, Seattle, Washington, USA, and was last updated in '99.

For power system reliability studies there are a couple of useful links, I found, that provide test systems in PPS/E format:

1. http://www.eleceng.adelaide.edu.au/Groups/PCON/PowerSystems/IEEE/BenchmarkData/index.html#TestSystemData,
2. Direct link to the IEEE 14 generator test system in PSS/E format:  http://www.eleceng.adelaide.edu.au/Groups/PCON/PowerSystems/IEEE/BenchmarkData/AUdata_Rev2_20080521.zip
3. Master Thesis example models in PSS/E format: http://www.ee.kth.se/php/modules/publications/reports/2007/XR-EE-EME_2007_009

Apparently, the test systems used in this Master thesis are from Kundur's book: "Power system stability and control". 

Other recent test systems, developed for dunamical studies were recently released by a small group of researchers form KIOS Research Center, Cyprus. 

Dynamic IEEE test systems similar to the ones described above and the IEEE 300 bus modified test system implemented in Powerworld can be downloaded from here:
