4.4.1 DRA-02 DISCONNECT INSTRUCTION (DR-L, DR-G)
4.4.1.1 Purpose
This test is intended to validate the client’s ability to respond to a disconnection signal.
4.4.1.2 Precondition
The controlled device is connected to the grid and consuming or generating power of at least 50% of its nameplate rating in kW.
4.4.1.3 Test Procedure
The steps SHALL be performed as described in Table 46. The test results SHALL be compared against the Expected Result column in Table 46.
Table 46 – Test steps for Communications Client – Demand Response Disconnection Instruction
Step No. | Manual or utility server step | Expected comms client result |
1 | The utility server configures an active control with an immediate start and opModConnect = false (representing OI0). | On the next poll of the utility server the client receives and starts the active control, by reducing load or generation (as appropriate) to 0W as determined in the relevant standard (see Table 43). On the next update to DERStatus the client reports an operationalModeStatus of 100 and alarmStatus = 0. |
4.4.1.4 Criteria
If during testing the client experiences one of the following events these are considered non- conformances with this requirement:
a) The controlled device continues to consume or generate power after receiving the active control.
b) The controlled device reports a DERStatus with no or an incorrect value for
operationalModeStatus.
Notes:
i) This test is only applicable to clients that intend to support OI0.
ii) The requirement for demand response enabled electrical products to report operationalModeStatus in DERSettings resources is present in the DEIP-published version of CSIP-AUS, however is no longer present in the SA HB 218 version of CSIP-AUS produced by Standards Australia. As such this test may be modified to reflect the appropriate version of CSIP- AUS that a client is intended to conform to.
4.4.2 DRL-01 LOAD OPERATIONAL INSTRUCTIONS (DR-L)
4.4.2.1 Purpose
This test is intended to validate the client’s ability to respond to the load operational instructions for which it wishes to claim conformance.
4.4.2.2 Precondition
The controlled device is connected to the grid and consuming power of 90% +/- 5% of its nameplate rating in kW.
4.4.2.3 Test Procedure
The steps SHALL be performed as described in Table 47. The test results SHALL be compared against the Expected Result column in Table 47.
Table 47 – Test steps for Communications Client – Demand Response Load OIs
Step No. | Manual or utility server step | Expected comms client result |
1 | The utility server configures an active control with opModFixedW = -75% (representing OI3) to start no more than 5 minutes in the future. | On the next poll of the utility server the client receives the active control. At the appropriate time (including any randomisation) the controlled device begins the active control by reducing load to no more than 75% of the reference value as determined in the relevant standard (see Table 43). On the next update to DERStatus the client reports an operationalModeStatus of 103 and alarmStatus = 0, and on next update to DERSettings with bit 7 of modesEnabled (i.e. opModFixedW) asserted. |
2 | The utility server configures an active control with opModFixedW = -50% (representing OI2) to start no more than 5 minutes in the future. | On the next poll of the utility server the client receives the active control. At the appropriate time (including any randomisation) the controlled device begins the active control by reducing load to no more than 50% of the reference value as determined in the relevant standard (see Table 43). On the next update to DERStatus the client reports an operationalModeStatus of 102 and alarmStatus = 0, |
and on next update to DERSettings with bit 7 of modesEnabled (i.e. opModFixedW) asserted. | ||
3 | The utility server configures an active control with opModFixedW = -0.01% (representing OI1) to start no more than 5 minutes in the future. | On the next poll of the utility server the client receives the active control. At the appropriate time (including any randomisation) the controlled device begins the active control by ceasing to consume load as determined in the relevant standard (see Table 43). On the next update to DERStatus the client reports an operationalModeStatus of 101 and alarmStatus = 0, and on next update to DERSettings with bit 7 of modesEnabled (i.e. opModFixedW) asserted. |
4 | The utility server configures an active control with opModFixedW = -100% (representing OI4) to start no more than 5 minutes in the future. | On the next poll of the utility server the client receives the active control. At the appropriate time (including any randomisation) the controlled device begins the active control by increasing load to more than 90% of the reference value as determined in the relevant standard (see Table 43). On the next update to DERStatus the client reports an operationalModeStatus of 104 and alarmStatus = 0, and on next update to DERSettings with bit 7 of modesEnabled (i.e. opModFixedW) asserted. |
4.4.2.4 Criteria
If during testing the client experiences one of the following events these are considered non- conformances with this requirement:
c) The controlled device continues to consume power more than the specified power after the active control is scheduled to commence (accounting for any randomisation).
d) The controlled device reports a DERStatus with no or an incorrect value for
operationalModeStatus.
Notes:
i) Step 1 in Table 47 is only applicable to clients that wish to claim conformance with OI3.
ii) Step 2 in Table 47 is only applicable to clients that wish to claim conformance with OI2.
iii) Step 4 in Table 47 is only applicable to clients that wish to claim conformance with OI4.
iv) The requirement for demand response enabled electrical products to report operationalModeStatus in DERSettings resources is present in the DEIP-published version of CSIP-AUS, however is no longer present in the SA HB 218 version of CSIP-AUS produced by Standards Australia. As such this test may be modified to reflect the appropriate version of CSIP- AUS that a client is intended to conform to.
4.4.3 DRG-01 GENERATION OPERATIONAL INSTRUCTIONS (DR-G)
4.4.3.1 Purpose
This test is intended to validate the client’s ability to respond to the generation operational instructions for which it wishes to claim conformance.
4.4.3.2 Precondition
The controlled device is connected to the grid and generating power of 90% +/- 5% of its nameplate rating in kW.
4.4.3.3 Test Procedure
The steps SHALL be performed as described in Table 48. The test results SHALL be compared against the Expected Result column in Table 48.
