10 MW of solar across 30 remote communities in the Northern Territory Medium penetration hybrid power stations are designed to displace a minimum of 15% of diesel

Understanding community expectations begins with community engagement Community support of the project is essential for long term operation

• earth leakage problems with the legacy equipment have

invalidated the data from the six months trial

• cloud forecasters will now be trialled at Maningrida

• as part of SETuP Knowledge sharing commitments the results will be made publically available

Questions

Naming conventions are as for ASIM: Pv = Photo Voltaic, Gen = Generator, Load = Load P = power, Q = reactive power, I = current Power P (kW), what is being used/generated now Instantaneous Penetration is the % of renewable power (kW) at this time Average Penetration is the % of renewable energy (kWh) over a period So a system with a Peak Instantaneous Penetration of 60% may result in in Average Penetration of 15%

PV101 naming conventions

Active control of generation and PV in order to maintain: (1) PvP <= SpinP So if all the PV disappears before a diesel is brought on line no load shedding or blackouts will occur We also need to maintain diesel loading above a threshold: (2) GenP >= GenMinP In order to avoid damage to diesel generation So control: GenMaxP and PvSetP in order to meet (1 ) and(2)

PV101 - equations

Keep enough spinning reserve online: GenMaxP >= GenP + max(PvP,GenSpinPPa) So loss of 100% of the Pv will be covered by the diesel We must limit PV output in order to the diesels loaded: PvSetP = LoadP - GenMinP The system must keep a diesel online all the time, the PV cannot create the grid (vars, ...) Finally: if minimum diesel loading is 40% the maximum penetration is 60% if the loads match the generators
