A crucial step in the worldwide effort to fight climate change and cut greenhouse gas emissions is the switch to electric cars (EVs). The capacity of our power systems to handle the growing demand for electricity, particularly from renewable sources, is one of the issues presented by this transformation. We must embrace the idea of smart electrification if we are to address this issue and fully utilize EVs’ potential to reduce the carbon footprint of transportation.
Smart Electrification: A Must
Implementing measures that improve the integration of renewable energy sources into the electrical grid while concurrently lowering peak demands and grid congestion is known as smart electrification. It includes a range of operational advantages, such as improved adaptability and capacity for energy storage. These advantages are essential for minimizing operational costs, limiting the curtailment of fluctuating renewable energy supply, and reducing greenhouse gas emissions.
What a Smart Charger Does
Smart charging is a key element of smart electrification. Unlike traditional uncontrolled charging, smart charging relies on intelligent algorithms to optimize the charging process. These algorithms take into account factors such as electricity prices, renewable energy availability, local grid congestion, and battery health. By doing so, smart charging minimizes the need for additional investment in generation, transmission, and distribution capacity, ultimately reducing costs for both utilities and consumers.
Unlocking the Potential of V2G
One significant advancement in smart electrification is Vehicle-to-Grid (V2G) technology, where EVs can supply power back to the grid. This capability helps reduce reliance on inefficient peaking generators, improving overall grid efficiency and reliability.
Benefits of a Distribution Grid
Smart charging has many benefits at the distribution grid level. In addition to improving voltage quality and lowering energy losses, it minimizes overloading of distribution system components. These advantages are crucial for addressing the increased demand for distributed energy resources (DERs) while remaining compliant with operational limitations.
Studies have repeatedly demonstrated how smart charging benefits distribution systems:
Peak loads and traffic are considerably reduced with smart charging, and as more EVs embrace bidirectional smart charging (V2G), the benefits become even more pronounced.
Uncontrolled EV charging reduces voltage losses, especially as EV adoption levels increase. Voltage stability in the distribution system is further enhanced by reactive power supplied by EVs.
Smart charging offers a number of benefits for power system operations, including:
- Savings per EV that range from USD 15 to 360 year.
- Reductions in CO2 emissions ranging from 0.1 to 2.5 tonnes per EV year.
- Peak load reductions per EV ranging from 0.2 to 3.3 kW.
- Cuts of up to 2400 kWh per EV each year in the amount of variable renewable energy that is curtailed.
On the Road to a Sustainable Future
The creation and implementation of business models that can enhance grid flexibility within the context of mobility are crucial for realizing these advantages. A key factor in guaranteeing a sustainable and ecologically friendly future for transportation is smart electrification, notably through intelligent charging schemes.
For a future of sustainable development, VinFast is making efforts to perfect electric vehicle lines as well as electric energy solutions for vehicles every day.
