🔊This paper mainly considers the economic and secure operation of the distribution network by leveraging the charging elastic of EVs. A two-stage stochastic rolling optimization framework for active-reactive power scheduling is established for the distribution network considering uncertain distributed resources, such as EVs and distributed wind/solar power. By decoupling active and reactive power scheduling, the first-stage mode focuses on the active power dispatch optimization to reduce the operation cost of the distribution network by EV aggregation, which is solved by simulation-based Rollout method. The second-stage model focuses on the reactive compensation optimization to improve the voltage stability of the distribution network based on the aggregated total power of EVs, which is solved by the scenario-based second-order cone programming. Numerical results demonstrate that this method can effectively improve the economic operation of the distribution network while enhancing its operational security.

The recycling of end-of-life (EOL) power batteries currently faces numerous challenges. This paper constructs a tripartite evolutionary game model involving the government, recycling enterprises, and electric vehicle (EV) owners. Through numerical simulation, it investigates how parameters such as the intensity of incentives and penalties, and the government’s regulatory costs, influence the stable points of the evolutionary game model. Results indicate that the government’s incentive and disincentive strategies affect the strategic choices of recycling enterprises and EV owners, with recycling enterprises prioritising formal recycling to a greater extent than EV owners.
