THE STUDY OF THE INTEGRATION OF WIND POWER IN THE PORTUGUESE GENERATION SYSTEM IS PART OF THE EC WIND POWER PENETRATION STUDY THAT IS INTENDED TO EVALUATE THE EXTENT TO WHICH WIND POWER CAN TECHNICALLY AND ECONOMICALLY BE FITTED INTO THE POWER PRODUCTION SYSTEMS OF THE MEMBER COUNTRIES.
IT IS ALSO AN AIM OF THE PROJECT TO IDENTIFY RELEVANT R&D PROJECTS THAT MAY FACILITATE THE PENETRATION OF WIND POWER IN THE EXISTING GENERATION SYSTEMS. THE RESULTS OBTAINED ARE EXPECTED TO SERVE AS BACKGROUND INFORMATION FOR THE UTILITIES AND FOR ENERGY POLICY BY THE COMMUNITY AND THE NATIONAL GOVERNMENTS AS WELL AS TO SUPPLY USEFUL INFORMATION FOR MARKET STUDIES BY THE WIND TURBINE MANUFACTURES.
SEVERAL TYPICAL SITES WERE SELECTED AS REPRESENTATIVE OF REGIONS WITH GOOD WIND POWER POTENTIAL AND, AFTER BEING DULY CHARACTERIZED, WIND SPEED AND ENERGY TIME SERIES WERE OBTAINED FROM THE DANISH RISOE NATIONAL LABORATORY. PRELIMINARY CALCULATIONS WERE CARRIED OUT FOR A SCENARIO WITH 5% WIND ENERGY PENETRATION IN THE YEAR 2000 COMPARED TO A REFERENCE SCENARIO WITHOUT WIND ENERGY USING EDP'S VALORAGUA MODEL. ENERGY AND CAPACITY CREDITS WERE ESTIMATED AS WELL AS THE CORRESPONDING ECONOMIC EVALUATION. SIMULATIONS FOR LOWER AND HIGHER PENETRATION SCENARI ARE CURRENTLY BEING CARRIED OUT.
The regions of Portugal that seem most likely to have good wind power resources have been studied. Detailed surveys (possibly along the lines of the one recently carried out by the Cornwall Energy Project) will offer a basis for the engagement of enterprises in the establishment of wind power projects. Good siting practices must be ensured in order to obtain both public acceptability of the projects and their economic success. The reliability of the wind turbines must be ensured, particularly for rough operational conditions. The cost of the machines must not be higher than the level of prices assumed in the guidelines and any reduction of this level would be helpful.
ACCORDING TO THE GUIDELINES THE RESEARCH INCLUDES CONSIDERATIONS CONCERNING THE FOLLOWING SUBJECTS :
- ENERGY CREDIT
- CAPACITY CREDIT
- CONTROL PROBLEMS
- ENVIRONMENTAL IMPACT
- VOLTAGE CONTROL AND REACTIVE POWER.
