IntroductionIntroduction

• The EU must meet its renewables targets:– For this, the large-scale integration of wind energy is essential.

• Europe’s electricity transmission networks – provide the route for the efficient transport of wind power from

turbines to consumers.– provide the means for efficiently managing wind variability by

harnessing diversity and backup energy sources.

• The EWIS project was initiated by the European Transmission System Operators in collaboration with stakeholders to address the best way to progress.– In particular, build upon the good work done by EWEA

Tradewind.

Objectives of the Study:Objectives of the Study:

To seek proposals for a generic and harmonized European wide approach towards wind energy issues addressing:– operational/technical aspects including grid

connection codes – wind energy related market issues– regulatory/market-related requirements

Methodology / ApproachMethodology / Approach

• Review present situation – 2008 Scenarios (done)

• Identify immediate challenges– 2015 Scenarios (in progress)

• With detailed assessment of:– Network technical performance– Market operation and economics– System operation facilities and procedures– Legal & regulatory requirements

Base case

Scenarios for Wind Power GenerationScenarios for Wind Power Generation

High wind power production causes regional overloading of transmission linesFundamental measures are necessaryHigher grid losses and reactive power demand in case of high wind power penetration

•Grid related measures• Corrective switching• Phase shifters• Further Grid re-enforcement

• Congestion Management• Reduction of cost effective power plants • Reduction of the daily auction capacity on congested channels

•Security Management (not taken into account by 2008)• Reduction of wind power generation due to system security reasons

INTERNAL ELEMENTS

Main FindingsMain Findings

High wind power increase from 41 GW in 2005 to nearly 67 GW already in2008 with a concentration in only 3 countries which represent more than 70% of the total installed capacityRegional high surplus of wind power generation results in large temporary load flows through neighbouring transmission systems with a reduction of system stability and an increasing effect on trading capacitiesGrid congestions within national grids –Need for additional/new grid infrastructureSystem operation at risk: In order to prevent the risks of large outages, manufacturers and operators must technically ensure that wind farms also support system stabilityIncreasing need for balance power and reserve capacity in some regionsIncreasing need for reactive power compensation and grid losses in case of high wind power production
