Grid stability

Calculation of surplus wind generation Hourly time series of wind generation and electricity demand are used for the calculation of the surplus wind generation. Furthermore, some assumptions are made following the arguments in DENA (2005). At least 700 MW of nuclear power plants and 160 MW of coal power plants are necessary to secure grid stability. The transmission capacity of the grid is... 

Countries that have large potentials of cheap fluctuating renewable electricity sources (solar or wind) that cannot be integrated into the national electricity grid (owing to problems of grid stability). 

Technology parameter Regulation Reserve power for grid stability and reliability Load shifting and load levelling... 

One California study suggests that vehicle owners could contribute to spinning reserves. These are contracts for generating capacity that is synchronized with the power line and when required must come up to its full output within 10 minutes. Spinning reserves contribute to grid stability especially during peak periods. 

Power factor 0.85 Meets American and international market require-ments for grid stability. 

Energy from remote wind turbines can be stored in lead-acid batteries designed to accept high power peaks. These batteries may also be used to filter power peaks and maintain grid stability when wind energy is added to the electrical grid system. 

Support of grid stabilization by providing active and reactive power in a flexible way... 

The utility has conducted grid stability studies on the transmission S3 em using a digital computer program. The study results have shown that the ROK transmission network is adequate to maintain stable system operation. 

External costs (1) radioactive emissions (2) long-term waste disposal (often already internalized) (3) accidents—liability (4) proliferation (5) avoided CO2 emissions (6) system effects (in particular, on electrical grid stability).
