How can electric vehicles support renewable energy systems with vehicle-to-grid?

Currently the whole planet is committed to the three "D"s revolution: Decarbonization, Decentralization and Digitalization. The first "D" is the most important one as practically all countries are committed to their to reducing emission and thus reduce global warming. Decentralization means to produce electricity as near as possible to the consumer thus cutting costs in investment in transmission lines and also reducing losses. Finally, the digitalization helps to manage the grid using big data and analytics, internet of things and smart grids plus AI. If the EV is supported with suitable storage management program, it can help stabilize the whole power system which is each day more dependent on variable Renewable Energy.systems.

Electric vehicles (EVs) support renewable energy systems through vehicle-to-grid (V2G) technology, which enables them to store excess renewable energy and feed it back into the grid during peak demand or instability. V2G provides grid stability, reduces reliance on fossil fuels, and allows EV owners to earn revenue by participating in grid services programs. By integrating with renewable generation, EVs mitigate intermittency, optimize energy use, and contribute to greenhouse gas reduction. This symbiotic relationship enhances the reliability and sustainability of both the transportation and energy sectors.

Vehicle-to-Grid (V2G) transforms electric vehicles into active grid participants. Unlike traditional EVs, V2G enables bidirectional energy flow—vehicles can contribute excess energy back. This enhances grid stability, integrates renewable energy, supports demand response, and offers economic incentives. Standardized communication protocols, challenges like standardization and infrastructure, and regulatory support are crucial. Ongoing research positions V2G to shape smart grids and sustainable energy systems, promising a resilient and sustainable energy future.

La tecnología de Vehículo a Red (V2G) facilita la gestión de carga adicional en las redes eléctricas, integrando energías renovables y convirtiendo los vehículos eléctricos en unidades de almacenamiento de energía. Con V2G, las baterías de vehículos pueden actuar como reservas para momentos de necesidad, devolviendo energía renovable a la red durante períodos de baja generación solar o eólica y equilibrando la demanda en horas pico. Puede contribuir a gestionar el exceso de electricidad generada por turbinas eólicas o paneles solares, apoyando así la gestión sostenible del suministro energético. La V2G puede desempeñar un papel crucial en la estabilidad de la red y en la gestión de la demanda y oferta de energía renovable en el futuro.

1 ) Bidirectional Chargers: capable of both charging the EV battery and allowing the battery to supply electricity back to the grid. These chargers must comply with communication protocols and standards such as ISO 15118 for seamless interaction with the grid. 2) Coordinating EV charging with periods of high renewable energy generation (e.g., midday solar power surplus) and utilizing EV batteries to supply energy back to the grid during periods of low renewable generation or high demand.

Die Herausforderungen sind vielschichtig: - Technisch: Es gibt aktuell keine Standards, die ohne interpretationsspielraum im der Ladeinfrastruktur (Wallbox) und EV umgesetzt werden können und eine Interoperabilität plug ´n play möglich machen. Dazu kommt, dass das bidirektionale Laden über AC oder DC realisiert werden kann. Speziell auf der AC Seite gibt es bisher keine Klarheit wie die Grid Code Compliance erfüllt werden soll. Die Automobilhersteller müssen hier know how und/oder starke Partnerschaften mit der Solarindustrie aufbauen. - regulatorisch: Es gibt bisher zahlreiche Verordnungen und Gesetze, die V2G Anwendungen behindern. Am wichtigsten ist aktuell die Doppelbesteuerung von ein- und ausgespeichertem Strom. -gesellschaftlich: ..

Let's talk about a V2G and renewable energy collaboration between E.ON and Virta, a Finnish energy corporation. They provided E.ON with a digital EV charging infrastructure that automates charging and energy export depending on indicators like as grid demand, energy price, and energy mix carbon intensity. This program, which began in the United Kingdom in 2020, aimed to show that V2G is a viable, sustainable, and profitable business option. The experiment revealed that V2G technology may help manage renewable energy demand and balance the grid better.

Vehicle-to-Grid (V2G) is making strides globally. Nissan's Leaf-to-Home in Japan allows Leaf owners to power homes during outages.

University campuses, like the University of Delaware, deploy V2G to balance local grids. These examples showcase V2G's diverse applications, from home energy resilience to large-scale grid integration, illustrating its potential across different contexts.

Die wohl fortschrittlichsten Ansätze für V2G werden aktuell in Utrecht (NL) und der Schweiz erprobt. In Utrecht sind Robin Berg ein Vorreiter in dem er sein Car sharing Unternehmen WeDriveSolar und eine gut ausgebaute AC BIDI Infrastruktur zur Erprobung der Netzstützung einsetzt. In der Schweiz sind die Akteure rings um SunToWheel Wegbereiter, die gemeinsam mit den Wallboxen von EVtec und Honda-e die praktische Umsetzung beweisen. Natürlich gibt es viele Forschungsprojekte unter anderen von Kostal, SMA Solar Technology und E3DC. Diese sind allerdings noch einige Jahre von der Produktreife entfernt.

Die Zukunft von V2G hängt wie so oft an der Politik. Je schneller die entsprechende Regulatorik auf den Weg gebracht wird, um so schneller "fliegen" die Business Cases der Aggregatoren. Sobald hierdurch ein monetärer Anreiz für den EV Fahrer erkennbar wird, kommt die Technologie in die Masse und niemand wird mehr von "Reichweitenangst" sprechen. Der eigene Vorteil und das "Gemeinwohl" des Netzes können so gleichzeitig erreicht werden.

Electric vehicles (EVs) can support renewable energy systems through Vehicle-to-Grid (V2G) technology. V2G enables EV batteries to store excess renewable energy during periods of low demand and supply it back to the grid when demand is high or when renewable energy generation is low. This helps balance the grid, smooth out fluctuations in renewable energy supply, and maximize the utilization of clean energy resources. Additionally, V2G can provide grid services such as frequency regulation and peak shaving, enhancing grid stability and reliability. Overall, V2G integration optimizes the synergy between electric vehicles and renewable energy systems, facilitating the transition to a more sustainable energy future.

Ich bin davon überzeugt, dass wir Innovationen benötigen, die einen nennenswerten Impact haben. Ich bin auch überzeugt, dass V2G für wenige Einzelne gut geeignet ist. Doch wie sieht es bei der breiten Masse aus? Wenn mein Auto am Abend und über Nacht am Hausanschluss hängt, kann ich die Batterie nutzen. Am Morgen komme ich dann zur Arbeit und lade mein Auto wieder auf (mit 3,6 bis 22 kW). Doch was ist wenn 100 oder 1000 weitere Personen es auch so machen möchten. Wie lässt sich V2G skalieren?

It's also important to consider the societal implications and behavioral aspects of V2G adoption. Beyond the technical, economic, and regulatory challenges, successful integration of V2G into renewable energy systems relies on widespread acceptance and active participation from EV owners. This entails raising awareness and fostering a positive perception of V2G benefits among consumers, as well as addressing potential concerns regarding privacy, control over vehicle usage, and perceived inconvenience. Incentivizing V2G participation through user-friendly interfaces, transparent communication channels, and flexible participation options can encourage greater uptake and engagement.

hen it comes to using V2G in practice, the most important thing is to make sure that EV drivers have enough energy in their car batteries when they need it. For example, a driver must be able to make a trip to work and back, at any time. This is the basic requirement of V2G and any other charging technology: The EV driver must be able to communicate when they want to unplug the car and how full the battery should be at that time.
