EVC向AEMO提交电动汽车数据建议文件

AEMO Via email:NEMReform@aemo.com.au Recommendations Paper: Electric Vehicle Data The Electric Vehicle Council (EVC) welcomes the opportunity to provide feedback to theAustralian EnergyMarket Operator(AEMO)on theconsultation paper(the paper).The EVCis the national peak body for the electric vehicle (EV) industry in Australia. Our mission isto accelerate the electrification of transport for a sustainable and prosperous future. Werepresent almost 100 businesses across the EV value chain, including car, bus and truckmanufacturers, importers, operators, charging infrastructure suppliers, battery reuse andrecycling companies, financiers, and network providers. Introduction The EVC welcomes AEMOscontinued attention to ensuringEV dataisasaccurate aspossible. Data gathering commissioned by AEMO feeds into theirInputs, Assumptions &Scenarios report(IASR)and IntegratedSystemPlan(ISP).Distribution Networks ServiceProviders(DNSPs)use these to planfor network augmentation. Other stakeholders suchas ChargePointOperators (CPOs) may use the forecasts forplanning where they shoulddeploy Electric Vehicle Supply Equipment (EVSE). There are three main areasof EV datarelevant to the paper; •Consumer charging behaviour,•EVSE deployment(locationally),and•EV uptake(locationally). Consumer charging behaviour It should be noted that although EV charging during peak time is understood to be low(~250W/EV), implementation of effective TOU tariffs drive it even lower (~110W/EV).1AEMO or their consultants have got this wrong in past ISPs, ignoring the data and insteadapplying a worst case scenario of between 65% and 75% convenienceor‘unscheduled’ charging in the step change scenario.2 A survey carried out by The Institute of Transportand Logistics Studies atthe University of Sydney last year found thatonly15% of EVowners charge in the evening (not all of those surveyed were on TOU tariffs).3This statisticis reinforced by comparable data from multiple surveys, indicating a consistent trend acrosssources.4 Further, a vehicle-grid (V2G) compatible vehicle exporting 5kW at peak time can effectivelyoffset the import of 20 EVs at this rate. V2G is kicking off in earnest in Australia in 2025.5 EVSE deployment NILM The paper outlines how some DNSPs are using NILM (Non-Intrusive Load Monitoring) totrain algorithms capable of detecting Level 2 EVSE on their networks. This is done byanalysing smart meter data and filtering for the distinctive consumption patterns of thesedevices. Collaboration among DNSPs—through sharing knowledge, methodologies, andtechnical insights—could accelerate the development and effectiveness of these tools,ultimately improving the quality of the data they rely on. The EVC see potential in this technology to be further refined to be able to detect Level 1EVSE and the other loads which are currently responsible for network peak demand,namely; Air conditioning, cooking loads and to a lesser extent, loads that are nottimedcorrectly such as hot water and pool pumps (these should be programmed to run at othertimes). Consumer Energy Resources (CER) such as west facing solar and home batteries also putdownward pressure on network peak demand, electricity prices and emissions. The EVCrecognises the home battery scheme being finalised by the Federal government that willbeincluded into the Small-scale renewable energy scheme.6This kind of initiative also drivesdown network peak demand and the EVC would like to see a similar scheme incorporateV2G in the near future. State electrical safety bodies The EVC has previously advocated to AEMO for inclusion of data gathering by stateelectricalsafety bodies that receive certificates of electrical safety/compliance fromelectrical contractors for all electrical works.7 Certificates of electrical safety in Victoria forexample already have a tickbox for whether a new Air Conditioner was a part of the workscarried out. It would be very simple to add another tickbox for whether something to supplyan EVSE was a part ofthe works.The certificates are electronic and so harvesting thedata will be straightforward where there is the will. The data can be anonymised, it is not necessary for it to be known down to the address level, what transformer it is on will satisfyDNSPs. Victorian DNSPs have access to smart meter data and ~99% of Victorian NMIs have asmart meter.8 The EVC recommends analysis of data aggregated up from the transformer,feeder and substation level to inform their network capacity maps as to how much sparecapacity is on the assets at all locations. This information could then be used by the DNSPtodetermine where augmentation or battery storage/V2G is required to handle demandfrom peak-time heat pump and cooking loads, the loads presently pushing up peak demand.CPOs could use the information to ascertain where capacity is available to deploy EVSEmore strategically.” Network capacity maps The EVC has long advocated for improvements to network visibility in the public
