When multiple DER are being represented by one LFDI as a Generating Facility Energy Management System (GFEMS) the communications software client shall provide a representative value for the whole site as below:
DERSettings | DERCapabilities | Aggregation |
setMaxVA | rtgMaxVA | Total |
setMaxVAr | rtgMaxVAr | Total |
setMaxVArNeg | rtgMaxVArNeg | Total |
setMaxW | rtgMaxW | Total |
Table 3 – Aggregation of DERSettings and DERCapabilities
DERStatus objects | Aggregation |
OperationalModeStatusType | 1 = Off: applies when ALL managed devices are off 2 = Operational mode: applies when at least one managed device is in operational mode 3 = Test mode: not used |
ConnectStatusType | 0 = Connected: applies if any device is connected but not in any of the subsequent states 1 = Available: applies if any device is available but not in any of the subsequent states 2 = Operating: applies if any device is operating but not in any of the subsequent states 3 = Test: not used 4 = Fault/Error: applies if any device is in Fault/Error state |
