Five good reasons to abandon synchronous time control

Time control maintains the average electrical frequency to its nominal value over the long run. This control currently suffers from numerous accepted beliefs that are deemed to justify this practice. This paper discusses these beliefs and highlights various reasons in favor of abandoning time control. In particular, time control exhibits a limited value compared to increased costs due to a higher operation complexity and a lower security. If time control has to be kept, this paper shows that current operational procedures should at least be improved in order to increase system security.
