How can we maximise the current valley-filling potential based on EV charging Demand?

To maximise the current valley-filling potential based on the EV charging demand and the peak hours of the power grid, we propose the following policy recommendations. First, on weekdays, increase the charging price from 17:00 to 22:00, and reduce it after 22:00.

Are people more willing to pay for public pile charging?

At various times on the weekdays, people with an annual household income of less than 100,000 CNY are more willing to pay for public pile charging than those with an income of more than 100,000 CNY; however, on weekends, this study showed the opposite result.

What is the WTP for a public charging pile?

For public charging piles, the WTP for charging from 10:00–17:00 on weekdays is widely distributed, which may be related to whether there is a private charger at home. On weekends, respondents' WTPs are relatively concentrated.

Why are EV charging prices so high on weekends?

On weekends, the WTP for charging from 10:00–17:00 by public chargers is the lowest, but the WTP for charging at home is the highest. On weekends, the WTP for charging after 22:00 is higher than the current charging price. A possible reason is that after the weekend is over, EVs need to be fully charged for the next day's commute. Table 5.

How are charging prices set?

The charging prices are set based on the current charging price obtained in the pilot study and the acceptable adjustment range (a decrease of 50% and an increase of 100%). After the final questionnaire design was completed, a small-scale online test was conducted. 4.3.3. Quality control We designed three criteria to filter out invalid answers.

How EV charging costs can be reduced?

The average peak-valley difference of thermal power output can be reduced by up to 11.7% during workdays. In summary, the implementation of the charging TOU price mechanism can effectively reduce the impact of EV charging loads on the power grid soon.
