the large-scale integration of electric vehicles into the power grid has significantly impacted the demand-side resources. Furthermore
the introduction of V2G technology in electric vehicles adds more uncertainties
posing significant challenges to the optimal scheduling of integrated energy systems. Aiming to solve this problem
a bi-level optimization scheduling strategy is proposed under a carbon trading mechanism
considering demand response to balance power supply and demand. A multi-scenario approach is employed to account for the uncertainty of wind and solar power output
and demand response optimization is utilized to determine the day-ahead energy load of EVs
which serves as a critical decision variable for real-time dispatching of EVs at the lower level. Finally
convex optimization algorithms are applied to obtain real-time EV charging and discharging strategies. Simulation results indicate that the proposed optimization scheduling model reduces the system's peak-to-valley load difference by 9.04%
effectively achieving peak shaving and valley filling while enhancing the economic efficiency of the system.
