How to meet the demand of EV infrastructure and maintain a stable grid – TechCrunch


As electric vehicles (EVs) become the new standard, charging infrastructure will become a mundane detail that blends into the landscape, in different locations of different providers, including privately owned charging stations, office parking lots, home garages, and government agencies. It will be available. Provided a place to fill the gap. A new US energy blueprint is needed to maintain a stable grid to support this national move to EV charging.

Biden administration announces 500,000 charging stations Installed and added nationwide Energy storage To facilitate the transition to EV. To integrate and migrate all of this new infrastructure, you need to balance the traffic on the grid and manage the growing energy demand beyond the power lines and storage itself.

Most EV infrastructure draws power from the grid. This adds significant demand as the scale grows. In ideal situations, EV charging stations place their own renewable energy generation in the same location as storage, but new programs and solutions are needed to make it available everywhere. NS Scope of scenario In recent years, a method of using renewable energy to power EV charging has been piloted in the United States.Ultimately, EV Power the grid..

These technological advances occur as we proceed with the energy transition. Nevertheless, EV infrastructure relies heavily on the US grid. Therefore, coordination among various stakeholders and changes in behavior among the general public are essential to meet energy demand and stabilize the grid.

Of the white house EV charging infrastructure fact sheet It presents a technical blueprint jointly undertaken by the Department of Energy and the Institute of Electricity. It is important that utilities, energy management and storage stakeholders, and the general public are included in the plan — that’s why.

Stakeholder collaboration

Currently, the charging infrastructure is fragmented in the United States. Many are privatized and I have a complaint Unless you drive a Tesla, it’s hard to find a charge while you’re on the go. Some EV owners are returning to driving petrol cars. There is reason to expect this to change rapidly.

ChargePoint and EVgo are two companies that are likely to become popular names as the EV network grows. A coalition of some of the largest utilities in the United States, including American Electric Power, Dominion Energy, Duke Energy, Entertainment, Southern Company, and the Tennessee Valley Authority, is called the Electric Highway Coalition. , Presentation Planning a regional network of charging stations across utility territories.

The network of exchanging private gas stations for EV charging is part of the puzzle. You also need to make it accessible to everyone at an affordable price and stagger the charging time. This is one of the central concerns of all stakeholders’ minds. Making charging available in different locations helps to diversify demand and balance the available power with the grid.

Different consumer needs, such as location, housing, work schedules, and economic conditions, require considerations and new solutions to make EVs and charging available to everyone. Imagine working in the suburbs, which is not suitable for rural or urban areas, and working night shifts in dense urban areas.

Biden schedule “$ 4 million to encourage strong partnerships and new programs to increase local or national workplace billing. [plug-in electric vehicle] Ownership of consumers in underserved communities. Partnerships and creative solutions are needed as well.

Opportunity to fully engage in the technology we already have

“50% of the savings needed to reach Net Zero by 2050 or 2045 are due to technology we don’t have yet,” said John Kerry. Said It’s been causing a fuss lately. He later revealed that there were some technologies that needed to get to work, with shorter broadcast times. In fact, we are just beginning to take advantage of existing renewable energy and energy transition technologies. We haven’t fully realized their potential yet.

Currently, utility-scale distributed energy storage is used for the simplest function: jumping in when energy demand peaks and keeping the grid stable through services called balancing and frequency tuning. .. However, as renewable energy becomes more widespread and loads such as EVs are electrified, peak demand will worsen.

The role of storage in EV charging stations seems to be well understood. Onsite storage is used daily to power the car at any time. Utility-scale storage has the same capabilities and can be used to store large amounts of renewable energy daily and supply it to the grid to balance EV demand.

The EV’s stable power system combines utility and utility-scale storage with a network of subsystems where energy storage is co-located with EV charging. All systems are tuned and synchronized to collect and dispatch energy at different times of the day, based on all factors that affect grid stability and renewable energy availability. That synchronization is handled by intelligent energy management software that relies on sophisticated algorithms to predict and respond to changes within a fraction of a second.

The model also allows you to manage electricity costs and EV demand on the grid. These subsystems can be municipally owned locations in low-income areas. Such subsystems collect power in storage assets and price them locally on their own terms. These systems allow residents to make their charges more affordable per day by providing an alternative to real-time electricity prices during peak demand, for example when using household outlets. You can motivate them to turn on the power there in time.

Behavior change

The biggest challenge for utilities is how to manage EV loads and motivate people to stagger their vehicle charging rather than waiting for them to return home in the evening during off-peak renewable energy generation. If everyone connects at the same time, you’ll be cooking dinner in the dark.

There are talks of billing at different times and motivating the public to diversify demand, but the motivation depends on demographics. Many people choose convenience over cost because they can charge at home and skip trips to “gas stations” (sometimes called “power plants” in the future).

In the way we currently operate, individual energy consumption looks like an independent and isolated event for consumers and homes. EVs require everyone, from utilities and private charging stations to consumers, to be more aware of demand on the grid and act as an energy-sharing community.

Therefore, diverse charging networks alone cannot solve the problem of overloading the grid. We need a new blueprint and behavioral change combination to manage the energy on the grid.
