Electric Vehicle Dispatching Strategy for Improving the Flexibility of AC/DC Hybrid Distribution Networks

A large number of electric vehicles have brought new challenges to the operation scheduling and development of distribution network. In this context, a multi-objective optimization model is proposed to guide electric vehicle users in large parking lots or residential communities to cooperate with grid scheduling through incentive electricity prices. The objective function is to maximize the profit of electric vehicle aggregators and minimize the flexibility deficit of AC-DC hybrid distribution network. Multi-objective particle swarm optimization was used to solve the problem. Finally, an example is given to verify the effectiveness of the proposed scheduling scheme by improving the IEEE33-node distribution system.
