Interface: i.xbos.demand_response_forecast

Description: Standard XBOS demand response forecast interface - this is an array of the following inputs for a given number of days (e.g., 5 days)

PONUM: 2.1.1.11

Properties

Name	Type	Description	Units	Required
date	integer	nanoseconds since the Unix epoch for a given day (at midnight local time)	ns	true
event_likelihood	integer	The likelihood of a DR event	event_likelihood	true
time	integer	nanoseconds since the Unix epoch	ns	false

Signals

• info:
  • event_likelihood
  • date
  • time
