The phrase "adequacy problems" is correct and usable in written English.
It can be used in contexts discussing issues related to the sufficiency or appropriateness of something, such as policies, systems, or methodologies.
Example: "The study revealed several adequacy problems in the current assessment framework, indicating a need for revisions."
Alternatives: "sufficiency issues" or "suitability concerns."
Load fluctuation or generation failure also causes a supply adequacy problem in conventional power systems.
The increasing share of variable renewables in European power systems create a downward adequacy problem, which deals with the ability of power systems to cope with periods of excess generation.
Solutions to supply adequacy problem must be based on a wide area grid platform, taking into account multiple time- and spatial-scale coherences of fluctuations among wind plants and with load fluctuations, and dispatching of flexible resources over a wide area grid platform. .
Solutions to supply adequacy problem must be based on a wide area grid platform, taking into account multiple time- and spatial-scale coherences of fluctuations among wind plants and with load fluctuations, and dispatching of flexible resources over a wide area grid platform.
The basic solution to the supply adequacy problem is to increase flexibility in a power system in order to respond to wind fluctuations, based on a wind area grid platform, while the basic solution to operation stability is to optimize response of wind turbines to grid disturbances, based on a local wind plant platform.
They were tested for sampling Adequacy, sphericity and problems of multicolliniarity and singularity using Kaiser-Meyer-Olkin (KMO hereafter), Bartlett's test of sphericity, and the value of determinant (R2) respectively.
Supply adequacy is a problem of static characteristics of wind power output determined from wind as primary fuel, in the time scale of minutes or above, while operation stability is a problem of dynamic characteristics of wind power output determined from turbine controls, in the time scale of seconds or below.
Both the patients and the experts gave high scores for the value and quality of the letters in terms of the description of the problem, adequacy of recommendations given, and courtesy and respect (mean (±standard deviation) 5.65 ± 0.79 for patients vs. 4.87 ± 0.79 for experts out of maximum score of 6).
· Follow up of the evolution of research and evaluation of its adequacy to solve practical problems.
Figure 2 illustrates basic concepts for solutions to the supply adequacy and operation stability problems.
