Step(s)

Result(s)

Server configures DefaultDERControl with

OpModExpLimW = 0W

Upon next poll of the DERProgramList the Client

receives the new DefaultDERControl

Server cancels all Active Controls

Upon next poll of the DERProgramList the Client

receives cancellation instruction

Client cancels all Active Controls

Server validates that the Client falls back to DefaultDERControl with export limit measurement of

0W (+/- 4%)

Step(s)

Result(s)

Server configures DefaultDERControl with setGradW

= 1% per second

Upon next poll of the DERProgramList the Client

receives the new DefaultDERControl

Client configures setGradW

Server confirms update to setGradW in DERSettings

Step(s)

Result(s)

Client subscribes to Server resource

Client is subscribed to Server

Client provides resource to the Server for

notifications

Server receives notification resource

Step(s)

Result(s)

Server notifies of new Active Control with

OpModExpLimW = 0W

Client receives the Active Control

Client starts the Active Control

Server validates exports measurements are reduced

to 0W (+/- 4%)

Step(s)

Result(s)

Server notifies of new Active Control with

OpModGenLimW = 0W

Client receives the Active Control

Client starts the Active Control

Server validates generation measurements are

reduced to 0W (+/- 4%)

Step(s)

Result(s)

Server notifies of new Active Control with

OpModEnergize = false

Client receives the Active Control

Client starts the Active Control

Server validates DER is de-energized with DERStatus

Server notifies of new Active Control with

OpModEnergize = true

Client receives the Active Control

Client starts the Active Control

Server validates DER is energized with DERStatus

Step(s)

Result(s)

Server notifies of new DefaultDERControl with

opModExpLimW = 0W

Client receives the new DefaultDERControl

Server notifies of cancellation to all Active Controls

Client receives cancellation instruction

Client cancels all Active Controls

Client falls back to DefaultDERControl with export

limit of 0W

Step(s)

Server notifies of new DefaultDERControl with

setGradW = 1% per second

Client receives the new DefaultDERControl

Client configures setGradW

Server confirms update to setGradW in DERSettings

Step(s)

Result(s)

Server configures Active Control with OpModExpLimW = 10000W

Upon next poll of the DERProgramList the Client receives the Active Control

Client receives the Active Control

Client posts back control response = 1 (received)

Client starts the Active Control

Client posts back control response = 2 (started)

Client completed the Active Control

Client posts back control response = 3 (completed)

After completion (control response = 3) of the previous Active Control and after the Client has started (control response = 2) the next Active

Control, it is cancelled by the Server

Upon next poll of the DERProgramList the Client receives the cancellation

Client receives cancellation

Client posts back control response = 6 (cancelled)

After the client has started the next Active Control, a new control with an overlapping control window is

sent

Upon next poll of the DERProgramList the Client receives the new Active Control

Client begins new control

Client posts back control response = 7 (superseded)

Step(s)

Result(s)

Server updates pollRate value from default of 300s

to 60s

Upon next poll of the FunctionSetAssignmentsList

the Client updates its new pollRate

Next FunctionSetAssignmentsList poll is made to

Server after 60s

Server receives poll from Client after 60s

Step(s)

Result(s)

Server generates a schedule of 24 sequential

controls

Client receives schedule of controls by notification or

by polling

Client provides control responses for schedule of

controls

Server receives corresponding control responses (1 =

received) for each control

Client progresses through schedule of controls

Server validates each control in the schedule is started at correct time using control responses (2 =

started)

Step(s)

Result(s)

Server configures a schedule of 5 active controls each with:

• duration = 120s

• randomizeStart = 60s

Client receives schedule of controls

• opModExpLimW = 10000W

Client executes entire control schedule

Server validates randomness of start times through

control responses

Step(s)

Result(s)

Server configures DefaultDERControl with

OpModExpLimW of 0W

Client receives the new DefaultDERControl

Communications between Server and Client are lost

Client completes current schedule of controls

Upon completion of Active Control schedule, Inverter(s) begins ramping down to

DefaultDERControl

Inverter(s) are operating at zero export

Communications between Server and Client are re- established 1 minute after the expiry of the current schedule. Active control is issued with

OpModExpLimW = 10000W

Client receives and ramps to new Active Control using setGradW (0.27% per second)

Step(s)

Result(s)

Client maintains connection and communications to

the Server for 3 consecutive days (72 hours)

Server maintains log of communications for this

period

Communications during this time are validated

offline by SA Power Networks

Validity of results are confirmed during certification
