In January 2022, the “Implementation Opinions on Further Enhancing the Service Guarantee Capacity of Electric Vehicle Charging Infrastructure” was issued, which further proposed exploring and promoting orderly charging, V2G technology, and other forms of interaction between EVs and power grid.
EVs with lead–acid batteries are capable of up to 130 km (81 mi) per charge. Nickel–metal hydride batteries are considered a mature technology. [ 37 ] While less efficient (60–70%) in charging and discharging than even lead–acid, they have a higher specific energy of 30–80 W·h/kg.
Congestion increased when storage was built in Zones 6 or 15, which suggests that lines 6–10 and 4–15 are needed to export renewable energy to load centers. When energy storage is available in these zones, the model chooses to export additional renewable energy to take advantage of the opportunity to reduce curtailment.
Building 1 GW of energy storage in Zones 1, 2, and 3 was only marginally less effective at reducing the system cost. Each of these zones was dominated by renewable energy generation, which emphasizes the point that lower system costs were related to additional renewable energy export to major load centers.
EV charging volumes are influenced by various factors, including the condition of a vehicle, the battery's state-of-charge (SOC), and the distance to the destination. However, power suppliers cannot easily access this information due to privacy issues.
Single-zone, 1 GW penetrations of each energy storage technology were modeled with a renewable energy penetration greater than 50% to identify the transmission zones where energy storage might have the greatest impact on the total cost of energy generation.
