Fig. 1: Modeling Framework for Urban Charging Load under Ultra-fast Fast Charging System (UFCS) adoption.

From: China’s urban EV ultra-fast charging distorts regulated price signals and elevates risk to grid stability

Fig. 1

a shows an overview of the modeling approach, where charging record data serves as the input, the model categorize charging stations and configures UFCS in multiple scenarios and introduces an optimization model to simulate on-site Energy Storage System (ESS) deployment under unregulated market and load-control scenarios, ultimately deriving the charging load profile under UFCS adoption. b illustrates the concept of simulating UFCS by upgrading existing charging stations to UFCS, thereby shortening charging durations and potentially increasing fluctuations in the city’s total charging load. c presents charging record data from 1,702 charging stations across Guangzhou, Shanghai, and Beijing with various land use types, used to estimate the charging load profiles of the three cities.
