| Objectives | Primary project objectives of the project include:* Determine a range of connection cost options for the customer, depending upon their total income requirements, pay-back period expectations, and other business model considerations. * Produce enhanced network design assessment tools that take account of these options. * Determine whether V2G can support networks during constraint periods, and to what extent, by: A) Being allowed to discharge onto the network during periods of high load; and B) Being inhibited from fully charging during constraint periods* Produce new models of substation profiles that include various levels of V2G charger implementation. * Determine V2G charger impact on power quality. * Develop and disseminate guidance for other DNOs and interested parties. The project is research/knowledge development through a design, install, assess, mitigate and disseminate project. The project will produce a design assessment process and associated design guidance for V2G connections. It will also produce guidance on where and how V2G may be used to mitigate network issues. Delivery of the objectives detailed above, or an analysis of why they are not important will determine project success. | |
| Abstract | The potential emergence of Vehicle to Grid (V2G) services could mean that a high proportion of electric vehicles not only charge from our network but also discharge on to it as they provide fast frequency response to National Grid and, potentially, other grid services. This is a new feature on the Northern Powergrid network and the impact is not fully understood. This is a pressing issue; the actual delivery technology is already well developed and could be quickly implemented. Financial incentives for vehicle owners could accelerate this further. The impact of large scale uptake of the V2G systems, on the following is unknown: Connections Process - how will our connections process need to change to recognize V2G and understand how we treat and charge for these enquiries, particularly multiple enquiries. Avoiding / Managing DNO constraints - The Customer Led Network Revolution project (CLNR) and all research to date have viewed electric vehicles (EVs) to be a potential problem to networks above certain penetration levels. This project will research whether bidirectional V2G will increase or mitigate the predicted network constraints. Power quality - CLNR and the My Electric Avenue (MEA) showed that there was no power quality issue associated with EV chargers at 3kW. However more frequent calls for charge or discharge to provide frequency support, or when exporting energy on to the network may cause voltage flicker or harmonic issues but this is currently unknown. the problem is now potentially urgent as V2G technology is already being installed in new electric vehicles. Whilst this has not been activated the potential for very fast uptake of the technology is clearly present. The project proposes a phased and carefully monitored roll-out of 1100 V2G sites. The V2G charging points and background technology are being provided by NUVVE and not funded by the project. This work will provide data from an extensive V2G charger implementation to allow the impact of this new type of network technology on, primarily the LV network, to be fully assessed. This in turn allows mitigation to be prioritised and operational and design practices to be optimised to support more general roll-out of V2G technology. The project will address the following: Planning; Installation and commissioning; Monitoring, analysis and determination of mitigating actions; and Closedown and dissemination. Analysis and mitigation activities are likely to be focussed on connections and design process, impact on network constraints and power quality although other learning is likely to be generated as the project proceeds. Analysis of customer behaviours with respect to V2G, and the potential economic drivers of that behaviour, will be assessed by NUVVE as part of this project.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
