New reports

February 15, 2011

Since the beginning of this program, we made many reports and assignments. I don’t want to upload all of them, but I would like to share the articles that I personally wrote:

Improvements in the transmission grid network for a succesful wind power integration: In this report I analyzed how the wind power development can be improved in Europe. j

Spatial planning in the region of Galicia. This region in Spain has a lot of installed wind power capacity. Why?

Spanish Wind Power Policy: A brief and simple diagram.


Leassons learned at Gotland University

From the last time I posted, we have learnt many things about the wind power industry. Here is a short summary of what we studied on this Master:

  • Principles of wind turbines: Components of wind turbines and the differences between synchronous and asynchronous generators must be known to understood the basic principles.
  • Climatology and Boundary Layer Theory: Kinetic energy from wind moves the blades, and thus electrical energy can be produced.
  • Aerodynamics: The shape and chord of blades are optimized by using formulas. Lectures provided by some accademics of Risoe and Uppsala universities were useful to understand these phisical principles.
  • Measurements Methods: Linear, non linear, CFD (Computational Fluids Dynamics) are useful to predict the wind resources at a determinated place by using MCP (measurement correlate and predict) techniques. Hence, software such as WindPro or WinSim are useful tools.
  • Wind Power potentials: Places located in cold climates or offshore wind farms have high potential in future but there are some considerations they must be valorated.
  • Grid Network: Before starting a new wind power project four words must be considered: Wind, wind, wind and infrastructure/grid network. Hence, it is important to know the point of common coupling (PCC) to connect the wind farm to the grid network.
  • Logistic: The other leg of the four words is obvious; roads, docks, and so on.
  • Public acepttance and environmental impact: Visual impact, flicker shadows, noises, consequences to the wildlife are other important aspects.
  • Policy and Legal Planning: Incentives and subsidiaries from administrations, legal frameworks… These frameworks can explain why some countries as Germany has such installed wind power capacity.

Politics and Cap&Trade.

July 17, 2010

I have just found an article on Renewable Energy Focus website that explains which countries are interested on increase the target to reduce the greenhouses reduction for 2020. On one hand, we have countries (Spain, Germany, Sweden) which want to achieve the target of reduction to 30% below 1990 emissions. Others, like the UK, Portugal, Austria or France that want to keep the 20% approved in the past years. And finally, countries such as Italy, Denmark, and Belgium which their interests are different and they want to reduce that demanding target.

The position of each country must be directly related to the “Cap and Trade” regulatory system. This program allows to the manufacturers of gases linked to global warning to “trade” pollution permits, or allowances among themselves. It is important to point out that the European Union Emission Trading System is currently the largest functioning Cap and Trade system for greenhouse gases in the world (the permits generate an industry of $140 billion per year).


Future of Wind Energy in Spain.

Spanish Wind Energy Evolution.

Spain is the fourth world’s biggest producer of wind power behind US, Germany and China with an installed capacity of 16 GW at the end of 2008 (the Spanish annual Power System is 91 GW). It means Wind Energy represents the 17% according to the official report by Red Eléctrica de España (Spanish Power Supply) in 2008.

Spain has grown very fast from the 90’s until now and Wind Energy production has overcome the Coal Power Energy and at this moment, and it is the third Spanish energy resource behind the Combine Cycle and Hydraulic Energy generation.

So, now it is the big question: Is the Wind Power to reach the 30% of Spain’s overall energy production?
