Major In order to provide optimum value and control and to meet the requirements of the ISO/utility, our units are required to send the following power data to the ISO/utility:
1) Regulation Set Point Feedback - a repeat of the control value sent from the ISO/utility,
2) Up Regulation Capacity Available - the up regulation capacity available to the ISO/utility,
3) Down Regulation Capacity Available - the down regulation capacity available to the ISO/utility,
4) Current Regulation Set Point - the regulation service that is currently being provided to the ISO/utility,
5) Baseline Power - the system load that would exist were the system not providing regulation services,
6) Instantaneous Power Flow, and
7) 15-Minute Rolling Average of Power Flow
One embodiment of the use of these parameters is outlined in Appendix I: http://lists.oasis-open.org/archives/energyinterop-comment/201108/bin00000.bin.
Additionally, new control strategies would allow the ability to provide several energy parameters important to energy storage applications, including:
8) Stored Energy - amount of energy currently stored
9) Target Energy Storage - desired energy storage level
10) Available Energy Storage - capacity available for further energy storage
The Energy Interoperation v1.0 specification currently supports two data classes: PowerFeedbackType and EnergyFeedbackType (from Figure 8-8, line 1110 of working draft). Steffes requests that consideration be given to supplement these two data classes with the above-listed 10 parameters as optional data classes within the standard. These data types are necessary to facilitate frequency regulation and other Smart Grid Control for ISO/Utilities.
