How can power management support the decarbonization and electrification of the transport sector?

1 Power system integration

One of the main challenges of integrating renewable energy sources into the power system is their variability and uncertainty. Unlike conventional power plants, renewable energy sources depend on weather conditions and cannot be easily dispatched or controlled. This creates fluctuations in the power supply and demand, which can affect the stability and quality of the power system. To cope with this challenge, power management needs to adopt smart grid technologies, such as advanced metering, communication, and automation, to enable real-time monitoring, forecasting, and coordination of the power system. Moreover, power management needs to leverage flexible resources, such as energy storage, demand response, and interconnections, to balance the power system and provide ancillary services, such as frequency and voltage regulation, to the transport sector.

2 Vehicle-to-grid services

Another challenge of electrifying the transport sector is the increasing demand for electricity and the need for charging infrastructure. Electric vehicles (EVs) not only consume electricity, but also have the potential to provide electricity back to the grid when they are parked and connected to a charger. This is known as vehicle-to-grid (V2G) services, which can offer multiple benefits for both the power system and the transport sector. For the power system, V2G services can help to smooth out the peaks and valleys of the power supply and demand, to increase the utilization of renewable energy sources, and to reduce the need for costly grid reinforcements. For the transport sector, V2G services can generate revenue for EV owners, reduce the total cost of ownership of EVs, and enhance the resilience of the transport system in case of power outages or emergencies.

3 Smart charging strategies

A related challenge of electrifying the transport sector is the optimal management of the charging process of EVs. Charging EVs at random times and locations can create congestion and overload in the power system, especially during peak hours or in areas with limited grid capacity. This can result in higher electricity prices, lower power quality, and higher emissions. To avoid these negative impacts, power management needs to implement smart charging strategies, which can optimize the timing, location, and rate of charging EVs based on various factors, such as electricity prices, grid conditions, battery state of charge, travel patterns, and user preferences. Smart charging strategies can also incorporate incentives or signals to encourage EV owners to participate in V2G services or to shift their charging to off-peak hours or locations with surplus renewable energy.

4 Electrified public transport

A further challenge of decarbonizing the transport sector is the promotion of low-carbon mobility modes, such as public transport, cycling, and walking. Public transport is a key component of sustainable urban mobility, as it can reduce traffic congestion, air pollution, noise, and accidents, while improving accessibility, equity, and social inclusion. However, public transport also requires a significant amount of energy and emits a considerable amount of carbon dioxide. To make public transport more environmentally friendly and efficient, power management needs to support the electrification of public transport modes, such as buses, trams, trains, and metro systems. Electrified public transport can reduce the dependency on fossil fuels, lower the operating costs and maintenance needs, and improve the comfort and safety of passengers. Power management also needs to ensure the adequate supply and distribution of electricity to electrified public transport modes, as well as the integration of renewable energy sources and energy storage systems.

5 Intermodal transport systems

A final challenge of decarbonizing and electrifying the transport sector is the coordination and integration of different transport modes and services. Intermodal transport systems refer to the seamless combination of various transport modes and services, such as public transport, EVs, car-sharing, bike-sharing, and ride-hailing, to provide efficient, convenient, and affordable mobility solutions for different user needs and preferences. Intermodal transport systems can reduce the reliance on private car ownership, increase the utilization of shared mobility services, and optimize the use of existing transport infrastructure and resources. Power management can support intermodal transport systems by facilitating the interoperability and compatibility of different charging systems and standards, by providing transparent and dynamic information and pricing for different transport options and services, and by enabling the exchange and aggregation of data and services among different transport stakeholders.
