Multi-Objective Economic Operation of Active Distribution Network Considering Electric Vehicle Charging and Discharging

As the number of electric vehicles gradually increases, the charging load will become a part that cannot be ignored in the operation of active distribution networks. Furthermore, considering the energy storage characteristics of electric vehicle batteries, through vehicle-to-grid technology enables electric vehicles to contribute to active distribution network operations by reducing operational costs and flattening the load curve. Concurrently, guiding users to use electricity orderly through electricity price can also achieve flattening the load curve and bring additional benefits to distribution network operators. This paper proposes a multi-objective economic operation model of active distribution network that incorporates vehicle-to-grid, distributed generation and uncertainty, and verifies the effectiveness of the model through a numerical example.
