Re: [EnergyPlus_Support] Energy Management System (EMS)



Hi Miroslava,

Is there any reason this has to be done at runtime? You might find it easier to create a Schedule:File object where you can use Excel's random functions and logic to build your file based on the logic you need before running the simulation.

Hi All,


Is it possible to generate random number by using EMS that will be applied every timestep. I saw in the manual that random numbers could be generated by using @RandomUniform and/or @RandomNormal built functions but I do not know how to set it to change every timestep. 


For my project I have to vary temperature setpoint every 15 min by adding and subtracting 0.5C depending on the random number. For example, random number is between 1 and 10 and if it is <3 0.5C is added to setpoint, if it is >8 0.5 is subtracted and the rest of time no change occurs. 


Many thanks,


Regards,

Miroslava
