Abstract
This paper presents an overview of the findings of the intraday use case in the Bidirectional Charging Management project's pilot study. The intraday use case aims to trade energy for the financial profit of the customers. Each day the flexibility of the EV fleet is forecasted for the next day accordingly a load forecast is predetermined, and the forecasted flexibility is used to make trades on the continuous intraday market. The customer behaviour is a key aspect for the success of the intraday use case, as it determines the provided flexibility. Another factor is the performance of the system itself. The optimizations of scheduling improved the execution of trades from 58% for charging and 36% for discharging in April to 79% for charging and 61% for discharging in July. The round-trip efficiency of the intraday use case was determined at 80% which is competitive with storage methods such as pumped storage power plants. To increase the revenues of the use case further optimizations are still possible since for example the trades are limited to the night and thus only hourly spreads in the night time were taken advantage of.
