Peak and valley electricity prices energy storage charging piles

Why do we need more electricity during peak hours?

Guiding users to use more electricity during the peak hours of wind and solar power generation and less electricity during valley hours also helps increase the consumption of renewable energy, increase the proportion of renewable energy power generation in the grid and achieve more carbon emissions reduction ( Rupp et al., 2020 ).

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 much does it cost to charge an EV?

For public charging, the price of 2.2 CNY/kWh is enough to persuade most EV owners to switch to other times, no matter on weekdays or weekends. 5.2. Consumers' heterogeneity 5.2.1. Consumers' preferences for charging times The 11 consumer background factors collected in the questionnaire were analysed by adding interaction terms to MXL.

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.
