“…Copula functions retain variable correlation structures very well in data sampling [36], which is important in accurate event-based EV DR modelling. Previously copula functions have, for instance, been used to optimize and model charging schedules of EVs participating in implicit DR [37,38], to analyze the impact of EV charging on microgrids [39], to model EV charging in energy management algorithms [40], and to simulate EV charging events [36]. However, there exists no previous studies applying multivariate copulas with real EV charging event data in maximal FCR-D potential simulation.…”
