Optimal Scheduling Strategy of Microgrid with Electric Vehicles Based on Demand Response Guidance

Under the guidance of the concept of low-carbon travel, aiming at the challenges brought by the large-scale grid connection of electric vehicles to the safe and reliable operation of the microgrid system, this paper proposes a microgrid optimization scheduling strategy considering the access of electric vehicles. Firstly, the road network with complex road conditions is normalized, and the optimal scheme of electric vehicles scheduling route is formulated based on Floyd algorithm. Then, considering the active network loss and node voltage deviation of microgrid, an optimal scheduling model of microgrid considering unit operation constraints is established. Finally, based on the extended IEEE33-bus test system, the simulation analysis is carried out to verify the impact of network reconfiguration and flexible load participation in demand response on the optimal scheduling of microgrid. The simulation results show that this method is beneficial to improve the voltage quality of microgrid, reduce the peak-valley difference of load curve and improve the system operation profit.
