Objective
THE PURPOSE OF THE "PENETRATION STUDY" IS TO EXAMINE THE EXTENT TO WHICH IT IS FEASIBLE, TECHNICALLY AND ECONO+ICALLY, TO INTEGRATE WIND POWER INTO THE DANISH POWER SYSTEM MAINTAINING THE QUALITY OF THE ELECTRICITY SUPPLY AT THE USUAL LEVEL.
The methodology of wind farm analysis is based on the following steps:
the definition of a reference scenario for the year 2000;
the definition of an alternative scenario with a defined amount of wind power production;
the calculation of a time scale for electrical load and district heating from combined heat and power (CHP) production;
the calculation of a time scale for wind power production;
simulation of operation for 1 year;
the calculation of contribution margins and the difference in operating costs;
the calculation of investment schedules;
an economic evaluation and sensitivity analysis;
demonstration of differences in environmental impact.
The conclusion is that expansion of the wind power capacity to 5 % is likely to be acceptable as far as the transmission system is concerned. The limit depends on the siting, but expansion to 10% or 15% is considered to exceed the limit.
SCENARI WITH 5, 10 AND 15 % WIND ENERGY HAVE BEEN ANALYSED. THE ELSAM EXPANSION PLAN FOR THE YEAR 2000 HAS BEEN USED AS THE REFERENCE SCENARIO.
DIFFERENT 5 % SCENARI HAVE BEEN ANALYSED TAKING INTO ACCOUNT THE FOLLOWING FACTORS :
- ADDED WIND POWER CAPACITY
- REDUCED CONVENTIONAL CAPACITY
- ADDED LOAD CONTROL CAPACITY
- ADDED ENERGY STORAGE CAPACITY.
THE PRELIMINARY RESULTS INDICATE THAT THE WIND POWER SCENARI ARE UNPROFITABLE.
A NUMBER OF OPERATIONAL DIFFICULTIES E.G. LOAD CONTROL AND LOAD GRADIENTS MUST BE ANALYSED IN MORE DETAILS IN THE FUTURE.
