3.4.5.2 Test Procedure

The steps SHALL be performed as described in Table 39. The test results SHALL be compared against the Expected Result column in Table 39.

‌Table 39 – Test steps for Communications Client – Scheduling

3.4.5.3 Criteria

If during testing the client experiences one of the following events these are considered non- conformances with this requirement:

a) The client does not receive and respond correctly to the schedule of controls.

‌3.4.6 ALL-15 RANDOMISATION (A)

3.4.6.1 Purpose

This test is intended to validate the client’s support for randomization using the randomizeStart attribute.

3.4.6.2 Test Procedure

The steps SHALL be performed as described in Table 40. The test results SHALL be compared against the Expected Result column in Table 40.

‌Table 40 – Test steps for Communications Client – Randomisation

3.4.6.3 Criteria

If during testing the client experiences one of the following events these are considered non- conformances with this requirement:

a) The client does not properly implement randomisation.

‌3.4.7 ALL-16 COMMUNICATION LOSS (A)

3.4.7.1 Purpose

This test is intended to validate the client’s ability to ramp to the DefaultDERControl when communications are lost with the utility server.

3.4.7.2 Precondition

The DER is importing or exporting at the connection point at least 2000W or 50% of its rated power, whichever is smaller. The utility has a current active control in operation, with opModImpLimW / opModExpLimW set to 10000W.

3.4.7.3 Test Procedure

The steps SHALL be performed as described in Table 41. The test results SHALL be compared against the Expected Result column in Table 41.

‌Table 41 – Test steps for Communications Client – Communications Loss

3.4.7.4 Criteria

If during testing the client experiences one of the following events these are considered non- conformances with this requirement:

a) The DER ramps down immediately on loss of communications, rather than waiting for the active control schedule to complete.

b) The DER continues to import/export at a higher level than the DefaultDERControl after the active control schedule expires.

c) The DER generation/load ramps up immediately on restoration of communications, rather than waiting for a new active control to be provided.

Notes:

i) This test is designed for either generation or load type DER – either opModExpLimW or opModImpLimW is used depending on the type of DER under test. DER capable of both generation and consumption (e.g. energy storage or V2G) may use either.

ii) The tester is responsible for determining an appropriate way to create a loss of communications between the comms client and test utility server. Examples may include disabling of physical

networking (e.g. unplugging of Ethernet cable or turning off of WiFi router), shutting down the test utility server, etc.
