How the AHEAD project is enabling smarter and more stable power systems in Europe
The electrification of transport is a cornerstone of Europe’s strategy to achieve climate neutrality. Electric vehicles (EVs) are no longer a niche technology but a rapidly expanding component of the energy landscape, driven by ambitious policy frameworks, technological innovation, and increasing societal awareness. As adoption accelerates, however, the implications for power systems become more complex, particularly at the distribution level, where most charging activity takes place.
Unlike traditional electricity demand, EV charging introduces new patterns characterised by high power, temporal concentration, and spatial clustering. Evidence gathered within the AHEAD project confirms that even moderate levels of EV penetration can lead to significant local stress on distribution networks when charging is not properly coordinated. These impacts include thermal overloads of cables and transformers, voltage deviations, and increased operational uncertainty for distribution system operators (DSOs).
At the same time, charging behaviour is far from uniform. It is shaped by a combination of user preferences, mobility needs, infrastructure availability, and external factors such as electricity prices and weather conditions. Analyses performed within AHEAD show that, while home charging remains the dominant mode, other contexts such as workplaces, public parking areas, and fast-charging stations exhibit very different characteristics, both in terms of predictability and flexibility potential.
These developments are fundamentally changing the nature of distribution grids. Systems that were traditionally designed for passive consumption must now evolve into dynamic, interactive environments capable of integrating large volumes of flexible and distributed demand.
From data to decisions: AI-driven planning of charging infrastructure
A central challenge in the transition to electric mobility is determining where charging infrastructure should be deployed to best serve users while minimising stress on the grid. Infrastructure that is poorly located or dimensioned can lead to inefficient investments and unnecessary network upgrades, undermining both economic and environmental objectives.
The AHEAD project addresses this challenge by developing advanced tools that combine artificial intelligence with power system modelling. These tools are designed to identify optimal locations for charging infrastructure by jointly considering mobility patterns, user behaviour, and grid constraints. By doing so, they enable a more efficient allocation of resources and support long-term planning strategies that anticipate future demand.
In addition to predictive models, AHEAD develops spatial mapping approaches that provide a comprehensive view of infrastructure deployment across different geographical and functional contexts. These include major transport corridors such as highways, where fast charging is essential, as well as industrial zones and logistics hubs that require high-power depot charging solutions. Urban environments and residential areas are also considered, with particular attention to overnight charging and the integration of charging infrastructure into existing urban systems.
Importantly, the project also explicitly considers heavy-duty vehicles and emerging use cases such as electrified maritime transport (e.g. vessels), broadening the scope of infrastructure planning beyond passenger cars.
This combination of AI-based prediction and spatial modelling allows stakeholders to move from reactive planning approaches to proactive, data-driven strategies. It also supports the development of decision-support tools that can be used by DSOs, municipalities, and private operators to evaluate different deployment scenarios and identify the most effective solutions.
Understanding charging behaviour and infrastructure needs
The effectiveness of planning and operation strategies depends critically on a detailed understanding of how EVs are actually used and charged. AHEAD places strong emphasis on data analysis, leveraging high-resolution datasets collected from a variety of real-world environments.
These analyses reveal significant diversity in charging behaviour. In residential settings, users often exhibit predictable patterns, with charging concentrated during evening and nighttime hours. In contrast, public charging infrastructure and fast-charging stations show much more variability, driven by factors such as trip patterns, availability of alternative charging options, and user preferences.
Importantly, many charging contexts offer substantial flexibility that is not yet fully exploited. For example, vehicles parked for extended periods at workplaces or in public parking facilities could potentially shift their charging in time without affecting user convenience. At the same time, fast-charging stations, which are essential for long-distance travel, introduce high-power peaks that require careful management to avoid grid congestion.
To support decision-making, AHEAD also develops a structured classification of charging infrastructure, linking technical characteristics such as power levels and connectivity with performance indicators and stakeholder requirements. This includes not only technical metrics but also economic, environmental, and user-related aspects, providing a comprehensive framework for evaluating infrastructure solutions.
Unlocking flexibility through smart and bidirectional charging
While infrastructure planning is essential, it is not sufficient on its own to address the challenges of EV integration. AHEAD, therefore, focuses on unlocking the flexibility inherent in EV charging, transforming vehicles from passive consumers into active participants in grid operation.
Smart charging strategies enable the modulation of charging processes in response to grid conditions, electricity prices, or user preferences. By shifting charging demand away from peak periods, these strategies can significantly reduce the impact on the grid and improve the utilisation of existing infrastructure.
In addition, bidirectional charging technologies allow EVs to feed energy back into the grid, providing additional services such as frequency support and local balancing. These capabilities are particularly relevant in systems with high shares of renewable energy, where flexibility is essential to manage variability and maintain stability.
AHEAD develops and validates a range of flexibility services, which can be activated through different mechanisms, including market-based signals, direct control by system operators, and autonomous responses embedded in charging systems. These services are designed to operate across multiple levels of the power system, from local distribution networks to broader system-level services that can also be relevant for transmission system operators.
Crucially, the integration of EV flexibility into energy markets creates new opportunities for value creation. By participating in flexibility markets, EV users and aggregators can generate additional revenue streams, while system operators benefit from increased operational efficiency and reduced need for infrastructure investments.
Innovative grid services for multi-level system support
The flexibility enabled by EVs can be translated into a wide range of grid services that address specific technical challenges.
At the distribution level, EVs can support congestion management by reducing or shifting demand in constrained areas, as well as voltage regulation through controlled charging profiles. At the transmission level, aggregated EV fleets can contribute to frequency control and system balancing, providing services that have traditionally been delivered by conventional generation.
At the level of individual users and buildings, EVs can be integrated into local energy management systems, supporting demand response programmes, enhancing self-consumption of locally generated renewable energy, and enabling more efficient use of energy resources.
This multi-level approach reflects the increasingly interconnected nature of modern energy systems and highlights the role of EVs as a key enabler of flexibility across different scales.
Exploring advanced charging technologies and system architectures
The successful integration of EVs also depends on the evolution of charging technologies. AHEAD investigates a broad spectrum of solutions, ranging from conventional conductive charging to more advanced and emerging technologies.
Conventional AC and DC charging systems remain the backbone of current infrastructure, with AC charging dominating in residential and workplace settings and DC fast charging playing a critical role along transport corridors. At the same time, bidirectional charging technologies are gaining increasing attention, as they enable new forms of interaction between EVs and the grid.
Wireless charging technologies, including both static and dynamic solutions, are also explored within the project. These technologies have the potential to improve user convenience and enable new use cases, such as automated charging in public transport systems or electric road systems, where vehicles can charge while in motion.
Each of these technologies presents different opportunities and challenges in terms of efficiency, cost, and grid impact. High-power charging, for example, can significantly reduce charging times but requires careful integration to avoid overloading the grid. Conversely, smart and bidirectional charging can help mitigate these impacts by providing additional flexibility.
By analysing these trade-offs, AHEAD contributes to the development of charging infrastructures that are not only technologically advanced but also compatible with the needs of future power systems.
Ensuring secure and resilient e-mobility systems
As EV charging infrastructure becomes increasingly digitalised, the role of information and communication technologies becomes central to system operation. However, this digitalisation also introduces new risks related to cybersecurity.
The EV ecosystem involves complex interactions between multiple actors, including vehicles, charging stations, backend systems, and grid operators. These interactions rely on communication protocols and data exchanges that can be vulnerable to cyber-attacks if not properly secured.
AHEAD addresses these challenges by analysing the ICT architecture of the EV value chain and identifying potential vulnerabilities across both physical and digital layers. The project explores how cyber-attacks could propagate through interconnected systems and develops models that can simulate such scenarios.
These models provide valuable insights into potential risks and support the design of mitigation strategies, including improved communication protocols, enhanced security measures, and better coordination between stakeholders. By integrating cybersecurity considerations into the design of EV integration solutions, AHEAD contributes to the development of a resilient and trustworthy e-mobility ecosystem.
Validating solutions in real-world environments
A key strength of AHEAD lies in its strong focus on validation through real-world demonstrators. These demonstrators are deployed across different European regions, reflecting the diversity of grid conditions, regulatory environments, and user behaviours.
In the Nordic region, demonstration sites are designed to test advanced charging strategies under constrained grid conditions, where the total charging capacity exceeds the available grid connection. This provides an ideal environment to evaluate load management and demand response solutions.
In Southern Europe, demonstrators focus on the integration of EV charging into urban grids and transport systems, including fleet charging at substations and hybrid real-simulation environments. In Western Europe, use cases include residential, public, and semi-public charging scenarios, as well as applications in maritime and touristic contexts.
These demonstrators allow the project to test its solutions under realistic conditions, validating not only their technical performance but also their scalability and applicability across different contexts. They provide a critical link between research and deployment, ensuring that the solutions developed within AHEAD can be effectively implemented in practice.
Impact on grid planning and operation
The integration of EVs requires a fundamental shift in the way power systems are planned and operated. Traditional approaches, based on deterministic assumptions and passive demand, are no longer sufficient in a context characterised by uncertainty and flexibility.
AHEAD contributes to this transformation by introducing advanced planning methodologies that incorporate probabilistic analysis, hosting capacity assessment, and flexibility-aware strategies. These approaches enable DSOs to better anticipate future scenarios and optimise their investment decisions.
By combining planning and operational perspectives, AHEAD supports a more integrated approach to grid management, where flexibility is not only a response to constraints but also a key resource for system optimisation.
A European perspective and long-term vision
The solutions developed within AHEAD are closely aligned with European policy objectives, including the Green Deal and the broader electrification of transport.
AHEAD emphasises the importance of interoperability, standardisation, and collaboration across stakeholders, recognising that the integration of EVs requires coordinated efforts across the entire value chain. Its methodologies and tools are designed to be scalable and adaptable, enabling their application across different countries and regulatory environments.
