How to meet EV charging demand and maintain a stable grid source

The development of the electric vehicle sector should increase demand for electricity as consumers connect more and more electric vehicles to the electricity grid to charge them. However, many power grids and distribution systems are already overloaded. Thus, charging vehicles when consumers need them, rather than during low-energy hours, can jeopardize the sustainability of electrical grids. Governments in countries that are actively purchasing electric vehicles will need to invest in stable yet flexible systems that can meet the increased demand for charging electric vehicles.

In particular, the US administration plans to spend $ 73 billion under the Energy Infrastructure Modernization Plan. Including the construction of thousands of miles of new sustainable transmission lines that will match the development of renewable energy sources. According to market analyst John Kemp of Reuters, the potential is theoretically sufficient. However, most consumers accept that they will charge their electric vehicles during off-peak hours. That is, at times of a drop in demand for electricity, for example, at night. In the United States, the minimum demand period runs from 10:00 pm to 6:00 am, according to the EIA's hourly power grid monitoring. The problem with charging electric vehicles is that consumers need to be convinced, including through incentives such as lower tariffs, to charge their vehicles outside of peak hours. This is necessary so that the grids can meet the growing demand for electricity from the electric vehicle market.

Energy demand is secured by capacity, but not infrastructure

“Given the historical rate of growth, it is expected that there will be sufficient generation capacity available to support the growing fleet of electric vehicles as it evolves. Even with the high growth rate of the electric vehicle market, ”says the US Department of State's December 2019 report. However, guided charging with smart meters and smart communication technologies to coordinate the charging of electric vehicles throughout the day will play an important role in the integration of electric vehicles. This will provide additional flexibility to reduce peak demand, the report said. At the same time, the Biden administration must solve the problems of the "invisible infrastructure." That is utility rates, smart charging policies, data availability, and equipment compatibility. The administration's infrastructure plan should also prioritize charging on the roads and tackle the “looming crisis of residential electrical circuits,” added Pecan analysts.

“We have to acknowledge that electrical infrastructure in some regions of the US lags behind similar infrastructure in many other parts of the world,” said research group CTO Scott Hinson.

Promotion of EV among the citizens of the country

Utilities facing a challenge to encourage people to shift from conventional vehicles to Electric vehicles during off-road renewable energy generation, while waiting to go home at night. If everyone comes in at the same time, cooking is done in the dark. There is talk of encouraging the population to replenish and expand demand at different times, but the reasons vary by demographic. Many people prefer low-cost and easy convenience because they can be displayed at home and not have to go to a charging station in the future.In our current industry, the use of individual energy is like a unique and isolated thing for consumers and households. When it comes to electric vehicles, everyone from private charging facilities and stations to consumers needs to know more about the power grid supply and become an energy-sharing community. Therefore, several charging networks cannot solve the overloading problem. Grid management must be combined with new behavioral change projects.

Transition Technologies will evolve as a changing factor

We have only started using existing renewable energy sources and energy transfer technologies. However, we need to maximize its full potential. Distributed blades for utilities and energy storage are now being used to maintain grid stability through services known as balancing and frequency control, with easy team action during energy demand peaks. However, with the advent of renewable energy and the electrification of taxes such as electric vehicles, demand will increase. The role of energy storage in EV charging stations needs to be well understood by the people of the country. Use your daily storage to charge your car whenever you want. A weighbridge has the same function and can be used to store a lot of renewable energy every day and feed it back to the grid to balance the demand and supply.

We need to combine facilities and convenient storage with an on-grid subsystem. In addition to charging the electric vehicle, energy storage is also set up in the grid subsystem. All systems are configured and synchronized, and energy is collected and sent at different times of the day, depending on each function that affects the stability of the network and the availability of renewable energy sources. This is controlled by intelligent energy management software. The software forecasts and the response to changes are very quick. This can also boost electricity prices on the grid and the demand for electric vehicles. These subsystems may be city-owned in low-income areas. These subsystems extract electricity from the storage facilities and deploy it locally on their terms. For example, these systems can encourage residents to provide electricity at certain times of the day, replacing real-time electricity rates, such as when using residential properties where demand is high.
