Hi all, Im Using EMS in Energy plus for making my Pump ON while my PV system production is higher than 3000 watts. Here is my Program:

  PV_Generation,      !- Name
  Average,                 !- Output:Variable or Output:Meter Index Key Name
  Electric Load Center Produced Electric Power;  !- Output:Variable or Output:Meter Name

  CHW_Loop_Sch_Modified,   !- Name
  CHW_Loop_Schd,           !- Actuated Component Unique Name
  Schedule:Compact,        !- Actuated Component Type
  Schedule Value;          !- Actuated Component Control Type

  CHW_Program,             !- Name
  BeginTimestepBeforePredictor,  !- EnergyPlus Model Calling Point
  System_Storage;          !- Program Name 1

  System_Storage,          !- Name
  IF (PV_Generation > 3000),  !- Program Line 1
    SET CHW_Loop_Sch_Modified = 1,  !- Program Line 2
  ELSE,                    !- A4
    SET CHW_Loop_Sch_Modified = 0,  !- A5
  ENDIF;                   !- A6

I got this Error:

** Invalid Output:Variable or Output:Meter Index Key Name =AVERAGE

** ~~~ ** For Output:Variable or Output:Meter = ELECTRIC LOAD CENTER PRODUCED ELECTRIC POWER

** ~~~ ** Entered in EnergyManagementSystem:Sensor=PV_GENERATION

** ~~~ ** Unique Key Name not found.

Please can someone guide me?

Please note:

  • HVAC,Average,Electric Load Center Produced Electric Power [W] is taken from my RDD File.
  • CHW_Loop_Schd is my pump schedule.

Thank you

Instead "Average" you have to put your Electric Load Center object name.

It requires the "Key Name", that is the name of the object associated with the variable thay you use as a sensor
