Assisting Communities to Connect to Electric Sustainable Sources (ACCESS) is a new, flexible connection agreement; which SSEPD may offer to community generators in transmission constrained areas. An ACCESS Connection Agreement continues to constrain generators in accordance with SSEPD standard policy for transmission constrained areas. However, the generator would be allowed to produce more than the constraint limit provided it simultaneously brings on sufficient additional demand within the local balancing area.
The aim of the PNDC testing was to demonstrate and test the functionalities of the ACCESS demand side management and inter-tripping scheme before trial implementation on the Isle of Mull. The ACCESS system has been tested at PNDC to prove functionality of the system, prove the fail safe operation of the system to communication failure and to evaluate the systems impact on power quality.
The findings from testing at the PNDC have been incorporated into the ACCESS system trial deployment on Mull (November 2015 onward). Specifically the updates relate to the dynamo hardware, the VCharge demand side management system, and the quantum heater hardware. The trial deployment on Mull has started as of November 2015.
The ACCESS system testing at the PNDC was completed in three stages. The test stages are listed below:
Power quality testing of the dynamo units (Task 7):
Testing of inter-trip scheme (Tasks 8 and 9)
End to End testing of the DSM system (Task 10)
End to end system functionality, failsafe capability and power quality impact evaluated
Intertrip scheme A and B functionality and failsafe capability evaluated
Dynamo hardware functionality, failsafe capability and power quality impact evaluated
