Mains frequency

Just checked the dynamic demand site and the frequency was down to around49.7 cycles almost down to the lower legal limit never seen that before

    (MWh and MW/h both being identical.)



    Oh dear, I can feel the ghost of my old physics teacher threatening to clip me about the ear for even thinking of uttering such a thing. The words something like  'dimensional homogeneity' drift across the mists of the years (possibly inappropriately). MWh are Mega Watt Hours - the product of power & time -  MW/h would be Mega Watts per Hour -  a rate of power - completely different units (by a factor of 1/hours²).

    Well, I can appreciate a grid control engineer could be interested in the concept of rate of change of power, if not a county planning committee. I would have thought Megawatts per minute would be more practical.
